A malignant tumor derived from primitive or embryonal lipoblastic cells. It may be composed of well-differentiated fat cells or may be dedifferentiated: myxoid (LIPOSARCOMA, MYXOID), round-celled, or pleomorphic, usually in association with a rich network of capillaries. Recurrences are common and dedifferentiated liposarcomas metastasize to the lungs or serosal surfaces. (From Dorland, 27th ed; Stedman, 25th ed)
A liposarcoma containing myxomatous tissue. (Dorland, 27th ed)
A multifunctional heterogeneous-nuclear ribonucleoprotein that may play a role in homologous DNA pairing and recombination. The N-terminal portion of protein is a potent transcriptional activator, while the C terminus is required for RNA binding. The name FUS refers to the fact that genetic recombination events result in fusion oncogene proteins (ONCOGENE PROTEINS, FUSION) that contain the N-terminal region of this protein. These fusion proteins have been found in myxoid liposarcoma (LIPOSARCOMA, MYXOID) and acute myeloid leukemia.

A benign tumor composed, wholly or in part, of cells with the morphologic characteristics of HISTIOCYTES and with various fibroblastic components. Fibrous histiocytomas can occur anywhere in the body. When they occur in the skin, they are called dermatofibromas or sclerosing hemangiomas. (From DeVita Jr et al., Cancer: Principles & Practice of Oncology, 5th ed, p1747)

A new rapid technique for the fixation of thyroid gland surgical specimens. (1/347)

One of the main diagnostic problems in thyroid pathology is to distinguish between follicular adenoma and follicular carcinoma. Thorough sampling of the nodule's capsule is recommended in order to identify capsular invasion. However, during the hardening of the tissue, by the usual fixatives the capsule shrinks and rolls downwards and sometimes the capsule separates from the remaining tissue. The present work evaluates the use of "Lymph Node Revealing Solution" (LNRS) for the rapid fixation (2h) of different thyroid lesions as compared to that of formalin. Fifty-one unselected consecutive cases of thyroid nodules, which included various benign and malignant lesions, were examined. Each specimen was cut in two equal parts; one was fixed in LNRS, the other in formalin. Fixation in LNRS for 2 hours gave adequate results in sectioning and staining of the tissue, and excellent immunostains. Its advantage over formalin is the conservation of the natural relationship between the capsule and the rest of the tissue, on the same plane, as well as the short time required for the final diagnosis.  (+info)

Induction of solid tumor differentiation by the peroxisome proliferator-activated receptor-gamma ligand troglitazone in patients with liposarcoma. (2/347)

Agonist ligands for the nuclear receptor peroxisome proliferator-activated receptor-gamma have been shown to induce terminal differentiation of normal preadipocytes and human liposarcoma cells in vitro. Because the differentiation status of liposarcoma is predictive of clinical outcomes, modulation of the differentiation status of a tumor may favorably impact clinical behavior. We have conducted a clinical trial for treatment of patients with advanced liposarcoma by using the peroxisome proliferator-activated receptor-gamma ligand troglitazone, in which extensive correlative laboratory studies of tumor differentiation were performed. We report here the results of three patients with intermediate to high-grade liposarcomas in whom troglitazone administration induced histologic and biochemical differentiation in vivo. Biopsies of tumors from each of these patients while on troglitazone demonstrated histologic evidence of extensive lipid accumulation by tumor cells and substantial increases in NMR-detectable tumor triglycerides compared with pretreatment biopsies. In addition, expression of several mRNA transcripts characteristic of differentiation in the adipocyte lineage was induced. There was also a marked reduction in immunohistochemical expression of Ki-67, a marker of cell proliferation. Together, these data indicate that terminal adipocytic differentiation was induced in these malignant tumors by troglitazone. These results indicate that lineage-appropriate differentiation can be induced pharmacologically in a human solid tumor.  (+info)

Liposarcoma in association with total hip replacement. (3/347)

A possible relation between joint replacement and malignancy has previously been suggested in a few cases. In the majority of these cases, the authors found either malignant fibrous histiocytomas or osteosarcomas. We hereby report the first case of a liposarcoma in the vicinity of a joint prosthesis.  (+info)

Prognostic relevance of p53 alterations and Mib-1 proliferation index in subgroups of primary liposarcomas. (4/347)

For prognostic analyses of p53 alterations (p53 gene mutations + p53 immunopositivity) and Mib-1 proliferation index, we investigated 42 primary malignant lipomatous tumors for which complete clinical data and a long follow-up were available. p53 gene mutations were investigated by PCR-single strand conformation polymorphism-sequencing analysis, and immunohistochemistry was used to determine p53 protein expression and Mib-1 proliferation index. We found a mutation frequency of 14.3%. Nine liposarcomas (21%) were p53 immunopositive, and 11 (26.2%) had at least one p53 alteration. In myxoid liposarcomas, p53 alterations are not relevant to the presence or absence of round cell components. Pleomorphic liposarcomas showed a significantly higher proliferation index and more p53 alterations than myxoid or well-differentiated variants (P<0.001). When the Cox's regression analysis tumors of grade III histology (P = 0.005) was performed, the pleomorphic subtype (P = 0.016) and liposarcomas of retroperitoneal localization (P = 0.015) showed a significantly poorer prognosis. Moreover, we found that p53 alterations and high proliferation index correlated significantly with reduced overall survival. Their prognostic value seemed to be higher in myxoid than in pleomorphic liposarcomas. The metastasis-free survival was reduced in patients who had liposarcomas with p53 alterations (P = 0.171) or elevated proliferation index (P<0.016), reflecting a more aggressive behavior. In conclusion, the determination of p53 alterations and/or Mib-1 proliferation index is useful for assessing the prognosis of patients with liposarcomas and may especially be helpful in dividing different prognostic groups for patients with myxoid variants.  (+info)

The expression of MDM2/CDK4 gene product in the differential diagnosis of well differentiated liposarcoma and large deep-seated lipoma. (5/347)

Ordinary lipomas are cytogenetically characterized by a variety of balanced rearrangements involving chromosome segment 12q13-15, whereas well differentiated liposarcomas (WDL) show supernumerary ring and giant marker chromosomes, known to contain amplified 12q sequences. The tight correlation between the presence of ring chromosomes and both amplification and overexpression of MDM2 and CDK4 genes suggests the exploration of the possibility that immunocytochemistry (ICC) might assist in the differential diagnosis of lipoma-like well differentiated liposarcomas (LL-WDL) and large deep-seated lipomas (LDSL). For this purpose, 21 cases of the former and 19 cases of the latter tumours were analysed by ICC and, according to the availability of material, by molecular and cytogenetic approaches. All lipomas displayed a null MDM2/CDK4 phenotype, whereas all LL-WDL showed MDM2/CDK4 or CDK4 phenotypes. Southern blot analysis performed on 16 suitable cases, complemented by fluorescence in situ hybridization and classical cytogenetic analysis in 11 cases, was consistent with, and further supported the immunophenotyping data. In conclusion, MDM2/CDK4 product-based immunophenotyping appears to represent a valuable method for the categorization of arguable LDSL.  (+info)

Influence of biologic factors and anatomic site in completely resected liposarcoma. (6/347)

PURPOSE: Soft tissue sarcoma (STS) encompasses a group of neoplasms that are anatomically and biologically diverse. Retroperitoneal/visceral (RP/V) tumors have a poorer prognosis than extremity/trunk (E/T) lesions, and this has been attributed to frequent presentation with tumors of large size and multiorgan involvement that precludes complete resection. The worse prognosis that is associated with RP/V tumors has also been thought to be histopathologically dependent and not necessarily related to anatomic site. The aim of this study was to determine the role of anatomic site and biologic features in prognosis and outcome in patients after complete resection by examining a large cohort of STS patients with a single histopathology, ie, liposarcoma. METHODS: All patients who were treated for liposarcoma from July 1, 1982, through July 1, 1998, were included. Univariate analyses were performed using log-rank test and Kaplan-Meier estimates, and multivariate analyses were performed using Cox regression. The three end points examined were local recurrence (LR), distant recurrence, and disease-specific survival (DSS). RESULTS: Seven hundred twenty patients with liposarcoma were evaluated, and of these, 460 had completely resected primary or completely resected locally recurrent disease. Breakdown of anatomic site was 65% E/T (n = 301) and 35% RP/V (n = 159). The median follow-up period for patients who underwent complete resection was 42 months (range, 1 to 194 months). We found that RP/V site is a poor prognosticator that is independent of patient sex and age; tumor size, grade, and margin; and recurrent presentation. Sixty-nine percent of patients with RP/V tumors who died had local disease only and no distant metastasis at the time of death. CONCLUSION: In liposarcoma, tumor location exerts as strong an influence on prognosis as biology. In contrast to extremity liposarcoma, LR without distant metastasis often results in death for patients with RP/V tumors. For these patients, local control accomplished by complete surgical resection +/- adjuvant radiation therapy should impact strongly on DSS.  (+info)

The chimeric FUS/TLS-CHOP fusion protein specifically induces liposarcomas in transgenic mice. (7/347)

The characteristic t(12;16)(q13;p11) chromosomal translocation, which leads to gene fusion that encodes the FUS-CHOP chimeric protein, is associated with human liposarcomas. The altered expression of FUS-CHOP has been implicated in a characteristic subgroup of human liposarcomas. We have introduced the FUS-CHOP transgene into the mouse genome in which the expression of the transgene is successfully driven by the elongation factor 1alpha (EF1alpha) promoter to all tissues. The consequent overexpression of FUS-CHOP results in most of the symptoms of human liposarcomas, including the presence of lipoblasts with round nuclei, accumulation of intracellular lipid, induction of adipocyte-specific genes and a concordant block in the differentiation program. We have demonstrated that liposarcomas in the FUS-CHOP transgenic mice express high levels of the adipocyte regulatory protein PPARgamma, whereas it is not expressed in embryonic fibroblasts from these animals following induction to differentiation toward the adipocyte lineage, indicating that the in vitro system does not really reflect the in vivo situation and the developmental defect is downstream of PPARgamma expression. No tumors of other tissues were found in these transgenic mice despite widespread activity of the EF1alpha promoter. This establishes FUS-CHOP overexpression as a key determinant of human liposarcomas and provide the first in vivo evidence for a link between a fusion gene created by a chromosomal translocation and a solid tumor.  (+info)

Monoclonality of multifocal myxoid liposarcoma: confirmation by analysis of TLS-CHOP or EWS-CHOP rearrangements. (8/347)

Multifocal presentation, defined as the presence of tumor at two or more anatomically separate sites, before the manifestation of disease in sites where sarcomas usually metastasize (e.g., lungs) occurs in about 1% of extremity soft tissue sarcomas (STSs). Debate still persists whether multifocal STSs represent an unusual pattern of metastasis or multiple separate primary tumors. Among STSs with multifocal presentation, myxoid liposarcoma is the predominant histological type. This subtype of liposarcoma contains the specific t(12;16) chromosomal translocation, which results in rearrangement of the TLS and CHOP genes that is clone specific at the DNA level. We, therefore, sought to address the question of clonality by molecular analysis in six patients who presented with either synchronous or metachronous multifocal myxoid liposarcoma. In all six cases, adequate frozen tumor was available for DNA extraction from at least two distinct anatomical sites. Southern blot analysis using CHOP, TLS, and EWS cDNA probes was performed on genomic DNA. Five cases contained a TLS-CHOP rearrangement, and one case had the variant EWS-CHOP fusion (seen in <5% of cases). The size of the rearranged CHOP fragment differed among the six patients, as expected, but was identical in all anatomically separate tumor samples from each patient. Likewise, the sizes of the rearranged bands observed with either the TLS or EWS probes supported the monoclonality of all cases. Our results confirm the monoclonal origin of multifocal myxoid liposarcoma, establishing the metastatic nature of distant soft tissue lesions in these cases. It remains unclear whether this unusual pattern of metastasis represents an intrinsic property of this subset of myxoid liposarcoma or merely a rare chance occurrence. The clinical outcomes observed in this small series suggest that the prognosis of multifocal myxoid liposarcoma is poor, regardless of its often bland or "low-grade" histological appearance.  (+info)

Liposarcoma is a type of soft tissue sarcoma, which is a cancer that develops in the soft tissues of the body, such as fat, muscle, nerves, blood vessels, and fibrous tissues. Specifically, liposarcoma arises from fat cells (adipocytes) or their precursors.

There are several subtypes of liposarcoma, which differ in their appearance under the microscope, genetic features, and clinical behavior. These include well-differentiated, dedifferentiated, myxoid, round cell, and pleomorphic liposarcomas. The most common sites for liposarcoma are the thigh, retroperitoneum (the area behind the abdominal cavity), and the buttock.

Liposarcomas can grow slowly or rapidly, and they may spread to other parts of the body (metastasize) through the bloodstream or lymphatic system. Treatment typically involves surgical removal of the tumor, often followed by radiation therapy and/or chemotherapy. The prognosis for liposarcoma depends on several factors, including the type and grade of the tumor, its size and location, and whether it has spread to other parts of the body.

Liposarcoma, myxoid type, is a specific subtype of liposarcoma, which is a malignant (cancerous) tumor that develops from fat cells. Myxoid liposarcoma is characterized by the presence of a gel-like substance in the tumor tissue. It usually occurs in deep soft tissues, such as muscles, tendons, and ligaments, and can be found in various parts of the body, but it most commonly affects the thigh.

Myxoid liposarcoma tends to grow slowly and has a better prognosis compared to other subtypes of liposarcoma. However, it can still metastasize (spread) to other parts of the body, such as the lungs, bones, and lymph nodes. Treatment typically involves surgical removal of the tumor, with radiation therapy and/or chemotherapy used in some cases to help reduce the risk of recurrence or spread.

FUS (Fused in Sarcoma) is a protein that in humans is encoded by the FUS gene. It is primarily located in the nucleus of the cell, but can also be found in the cytoplasm. FUS belongs to the family of RNA-binding proteins, which means it has the ability to bind to RNA molecules and play a role in post-transcriptional regulation of gene expression.

FUS has several functions, including:

1. Transcriptional regulation: FUS can interact with transcription factors and modulate the transcription of genes.
2. mRNA processing: FUS is involved in various aspects of mRNA processing, such as splicing, transport, localization, and stability.
3. DNA repair: FUS plays a role in DNA damage response and repair mechanisms.
4. Translational regulation: FUS can also regulate translation by interacting with ribosomes and other translational factors.

Mutations in the FUS gene have been associated with several neurodegenerative disorders, such as amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). These mutations often lead to an abnormal cytoplasmic accumulation of FUS protein, which can form aggregates and contribute to the pathogenesis of these diseases.

Retroperitoneal neoplasms refer to abnormal growths or tumors that develop in the retroperitoneal space. This is the area located behind the peritoneum, which is the membrane that lines the abdominal cavity and covers the abdominal organs. The retroperitoneal space contains several vital structures such as the kidneys, adrenal glands, pancreas, aorta, and lymphatic vessels.

Retroperitoneal neoplasms can be benign or malignant (cancerous). Malignant retroperitoneal neoplasms are often aggressive and can invade surrounding tissues and organs, leading to various complications. Common types of retroperitoneal neoplasms include lymphomas, sarcomas, and metastatic tumors from other primary sites. Symptoms may vary depending on the size and location of the tumor but can include abdominal or back pain, weight loss, and swelling in the legs. Diagnosis typically involves imaging studies such as CT scans or MRI, followed by a biopsy to determine the type and grade of the tumor. Treatment options may include surgery, radiation therapy, chemotherapy, or a combination of these approaches.

Neoplasms in adipose tissue refer to abnormal and excessive growths of cells that form tumors within the fatty connective tissue. These neoplasms can be benign or malignant (cancerous). Benign neoplasms, such as lipomas, are slow-growing and typically do not spread to other parts of the body. Malignant neoplasms, on the other hand, are cancerous and can invade surrounding tissues and spread to distant sites in the body (metastasis). An example of a malignant neoplasm in adipose tissue is liposarcoma. It's important to note that while some neoplasms may not cause any symptoms, others can cause pain, swelling or other uncomfortable sensations, and therefore should be evaluated by a medical professional for proper diagnosis and treatment.

A lipoma is a common, benign (non-cancerous) soft tissue growth. It is composed of adipose or fatty tissue and typically found just beneath the skin, but they can also occur deeper within the body. Lipomas are usually round, moveable, and painless, although they may cause discomfort if they grow large enough to put pressure on nearby nerves or if they're located in a sensitive area. They generally grow slowly over time. Surgical removal is an option if the lipoma becomes bothersome or grows significantly in size. It's important to note that while lipomas are typically harmless, any new lumps or bumps should be evaluated by a healthcare professional to confirm the diagnosis and rule out other more serious conditions.

Soft tissue neoplasms refer to abnormal growths or tumors that develop in the soft tissues of the body. Soft tissues include muscles, tendons, ligaments, fascia, nerves, blood vessels, fat, and synovial membranes (the thin layer of cells that line joints and tendons). Neoplasms can be benign (non-cancerous) or malignant (cancerous), and their behavior and potential for spread depend on the specific type of neoplasm.

Benign soft tissue neoplasms are typically slow-growing, well-circumscribed, and rarely spread to other parts of the body. They can often be removed surgically with a low risk of recurrence. Examples of benign soft tissue neoplasms include lipomas (fat tumors), schwannomas (nerve sheath tumors), and hemangiomas (blood vessel tumors).

Malignant soft tissue neoplasms, on the other hand, can grow rapidly, invade surrounding tissues, and may metastasize (spread) to distant parts of the body. They are often more difficult to treat than benign neoplasms and require a multidisciplinary approach, including surgery, radiation therapy, and chemotherapy. Examples of malignant soft tissue neoplasms include sarcomas, such as rhabdomyosarcoma (arising from skeletal muscle), leiomyosarcoma (arising from smooth muscle), and angiosarcoma (arising from blood vessels).

It is important to note that soft tissue neoplasms can occur in any part of the body, and their diagnosis and treatment require a thorough evaluation by a healthcare professional with expertise in this area.

Transcription Factor CHOP, also known as DNA Binding Protein C/EBP Homologous Protein or GADD153 (Growth Arrest and DNA Damage-inducible protein 153), is a transcription factor that is involved in the regulation of gene expression in response to various stress stimuli, such as endoplasmic reticulum (ER) stress, hypoxia, and DNA damage.

CHOP is a member of the C/EBP (CCAAT/enhancer-binding protein) family of transcription factors, which bind to specific DNA sequences called cis-acting elements in the promoter regions of target genes. CHOP can form heterodimers with other C/EBP family members and bind to their target DNA sequences, thereby regulating gene expression.

Under normal physiological conditions, CHOP is expressed at low levels. However, under stress conditions, such as ER stress, the expression of CHOP is upregulated through the activation of the unfolded protein response (UPR) signaling pathways. Once activated, CHOP can induce the transcription of genes involved in apoptosis, cell cycle arrest, and oxidative stress response, leading to programmed cell death or survival, depending on the severity and duration of the stress signal.

Therefore, CHOP plays a critical role in maintaining cellular homeostasis by regulating gene expression in response to various stress stimuli, and its dysregulation has been implicated in several pathological conditions, including neurodegenerative diseases, cancer, and metabolic disorders.

Muscle neoplasms are abnormal growths or tumors that develop in the muscle tissue. They can be benign (non-cancerous) or malignant (cancerous). Benign muscle neoplasms are typically slow-growing and do not spread to other parts of the body, while malignant muscle neoplasms, also known as soft tissue sarcomas, can grow quickly, invade nearby tissues, and metastasize (spread) to distant parts of the body.

Soft tissue sarcomas can arise from any of the muscles in the body, including the skeletal muscles (voluntary muscles that attach to bones and help with movement), smooth muscles (involuntary muscles found in the walls of blood vessels, digestive tract, and other organs), or cardiac muscle (the specialized muscle found in the heart).

There are many different types of soft tissue sarcomas, each with its own set of characteristics and prognosis. Treatment for muscle neoplasms typically involves a combination of surgery, radiation therapy, and chemotherapy, depending on the type, size, location, and stage of the tumor.

The spermatic cord is a fibrous structure that contains the vas deferens, blood vessels, nerves, and lymphatics, which provide passage for these structures between the abdomen and the scrotum in males. It is covered by several layers of protective sheaths, including the internal spermatic fascia, cremasteric fascia, and external spermatic fascia. The spermatic cord allows the testicles to be located outside the body, which helps maintain a cooler temperature for optimal sperm production.

Genital neoplasms in males refer to abnormal growths or tumors that develop in the male reproductive organs. These can be benign (non-cancerous) or malignant (cancerous).

Malignant genital neoplasms are often referred to as genital cancers. The most common types of male genital cancers include:

1. Penile Cancer: This occurs when cancer cells form in the tissues of the penis.
2. Testicular Cancer: This forms in the testicles (testes), which are located inside the scrotum.
3. Prostate Cancer: This is a common cancer in men, forming in the prostate gland, which is part of the male reproductive system that helps make semen.
4. Scrotal Cancer: This is a rare form of cancer that forms in the skin or tissue of the scrotum.
5. Penile Intraepithelial Neoplasia (PeIN): This is not cancer, but it is considered a pre-cancerous condition of the penis.

Early detection and treatment of genital neoplasms can significantly improve the prognosis. Regular self-examinations and medical check-ups are recommended, especially for individuals with risk factors such as smoking, HIV infection, or a family history of these cancers.

Sarcoma is a type of cancer that develops from certain types of connective tissue (such as muscle, fat, fibrous tissue, blood vessels, or nerves) found throughout the body. It can occur in any part of the body, but it most commonly occurs in the arms, legs, chest, and abdomen.

Sarcomas are classified into two main groups: bone sarcomas and soft tissue sarcomas. Bone sarcomas develop in the bones, while soft tissue sarcomas develop in the soft tissues of the body, such as muscles, tendons, ligaments, fat, blood vessels, and nerves.

Sarcomas can be further classified into many subtypes based on their specific characteristics, such as the type of tissue they originate from, their genetic makeup, and their appearance under a microscope. The different subtypes of sarcoma have varying symptoms, prognoses, and treatment options.

Overall, sarcomas are relatively rare cancers, accounting for less than 1% of all cancer diagnoses in the United States each year. However, they can be aggressive and may require intensive treatment, such as surgery, radiation therapy, and chemotherapy.

Human chromosome pair 12 consists of two rod-shaped structures present in the nucleus of each cell in the human body. Each chromosome is made up of DNA tightly coiled around histone proteins, forming a complex structure called a chromatin.

Chromosomes come in pairs, with one chromosome inherited from each parent. In humans, there are 23 pairs of chromosomes, for a total of 46 chromosomes in each cell. Chromosome pair 12 is the 12th pair of autosomal chromosomes, meaning they are not sex chromosomes (X or Y).

Chromosome 12 is a medium-sized chromosome and contains an estimated 130 million base pairs of DNA. It contains around 1,200 genes that provide instructions for making proteins and regulating various cellular processes. Some of the genes located on chromosome 12 include those involved in metabolism, development, and response to environmental stimuli.

Abnormalities in chromosome 12 can lead to genetic disorders, such as partial trisomy 12q, which is characterized by an extra copy of the long arm of chromosome 12, and Jacobsen syndrome, which is caused by a deletion of the distal end of the long arm of chromosome 12.

The mesocolon is a peritoneal fold that attaches the colon to the posterior abdominal wall. It contains blood vessels, lymphatics, and nerves that supply the colon. The mesocolon allows for the mobility and flexibility of the colon within the abdominal cavity. There are several parts of the mesocolon, including the mesentery of the ascending colon (right mesocolon), the transverse mesocolon, and the mesentery of the descending and sigmoid colon (left mesocolon).

I apologize for any confusion, but "dioxoles" is not a medical term or concept. It is a chemical term that refers to a specific type of organic compound containing a dioxole ring, which is a six-membered ring consisting of two oxygen atoms and two carbon atoms. Dioxoles can be found in various natural and synthetic substances, but they are not typically relevant to medical definitions or concepts.

If you have any questions related to medical terminology or concepts, I would be happy to help answer them for you.

Cell dedifferentiation is a process by which a mature, specialized cell reverts back to an earlier stage in its developmental lineage, regaining the ability to divide and differentiate into various cell types. This phenomenon is typically observed in cells that have been damaged or injured, as well as during embryonic development and certain disease states like cancer. In the context of tissue repair and regeneration, dedifferentiation allows for the generation of new cells with the potential to replace lost or damaged tissues. However, uncontrolled dedifferentiation can also contribute to tumor formation and progression.

Mediastinal neoplasms refer to abnormal growths or tumors located in the mediastinum, which is the central compartment of the thoracic cavity that lies between the lungs and contains various vital structures such as the heart, esophagus, trachea, blood vessels, lymph nodes, and nerves. Mediastinal neoplasms can be benign (non-cancerous) or malignant (cancerous), and they can arise from any of the tissues or organs within the mediastinum.

Benign mediastinal neoplasms may include thymomas, lipomas, neurofibromas, or teratomas, among others. These tumors are typically slow-growing and rarely spread to other parts of the body. However, they can still cause symptoms or complications by compressing adjacent structures within the mediastinum, such as the airways, blood vessels, or nerves.

Malignant mediastinal neoplasms are cancerous tumors that can invade and destroy surrounding tissues and may spread (metastasize) to other parts of the body. Common types of malignant mediastinal neoplasms include thymic carcinomas, lymphomas, germ cell tumors, and neuroendocrine tumors. These tumors often require aggressive treatment, such as surgery, radiation therapy, and chemotherapy, to control their growth and spread.

It is important to note that mediastinal neoplasms can present with various symptoms depending on their location, size, and type. Some patients may be asymptomatic, while others may experience cough, chest pain, difficulty breathing, hoarseness, or swallowing difficulties. A thorough diagnostic workup, including imaging studies and biopsies, is necessary to confirm the diagnosis and determine the best course of treatment for mediastinal neoplasms.

Tetrahydroisoquinolines (TIQs) are not a medical condition, but rather a class of organic compounds that have been studied in the field of medicine and neuroscience. TIQs are naturally occurring substances found in various foods, beverages, and plants, as well as produced endogenously in the human body. They have been shown to have various pharmacological activities, including acting as weak psychoactive agents, antioxidants, and inhibitors of certain enzymes. Some TIQs have also been implicated in the pathophysiology of certain neurological disorders such as Parkinson's disease. However, more research is needed to fully understand their roles and potential therapeutic applications.

Leiomyosarcoma is a type of cancer that arises from the smooth muscle cells, which are responsible for the involuntary contractions of various organs and blood vessels. It most commonly occurs in the uterus, soft tissues (such as muscles and fat), and the gastrointestinal tract.

Leiomyosarcomas can vary in their aggressiveness and may spread to other parts of the body (metastasize) through the bloodstream or lymphatic system. The prognosis for leiomyosarcoma depends on several factors, including the location and size of the tumor, the patient's age and overall health, and the extent of metastasis. Treatment typically involves surgical removal of the tumor, along with radiation therapy and/or chemotherapy to help prevent recurrence or spread of the cancer.

Proto-oncogene proteins, such as c-MDM2, are normal cellular proteins that play crucial roles in regulating various cellular processes, including cell growth, differentiation, and apoptosis (programmed cell death). When these genes undergo mutations or are overexpressed, they can become oncogenes, which contribute to the development of cancer.

The c-MDM2 protein is a key regulator of the cell cycle and is involved in the negative regulation of the tumor suppressor protein p53. Under normal conditions, p53 helps prevent the formation of tumors by inducing cell cycle arrest or apoptosis in response to DNA damage or other stress signals. However, when c-MDM2 is overexpressed or mutated, it can bind and inhibit p53, leading to uncontrolled cell growth and increased risk of cancer development.

In summary, proto-oncogene proteins like c-MDM2 are important regulators of normal cellular processes, but when they become dysregulated through mutations or overexpression, they can contribute to the formation of tumors and cancer progression.

Malignant fibrous histiocytoma (MFH) is not a specific type of histiocytoma; rather, it is a type of soft tissue sarcoma. Histiocytomas are benign tumors that arise from cells called histiocytes, which are part of the immune system. MFH, on the other hand, is a malignant (cancerous) tumor that can arise in various types of soft tissues, such as muscle, fat, tendons, and ligaments.

MFH was once thought to originate from histiocytes, but more recent research suggests that it may actually arise from undifferentiated mesenchymal cells, which are capable of developing into a variety of different cell types. MFH is the most common type of soft tissue sarcoma in adults over the age of 50 and typically presents as a painless mass in the extremities or retroperitoneum (the area in the back of the abdomen).

The tumor is characterized by the presence of fibroblastic and histiocytic-like cells, which can be quite pleomorphic (varied in shape and size) and may contain numerous mitotic figures (indicating rapid cell division). Treatment typically involves surgical excision, often followed by radiation therapy and/or chemotherapy. The prognosis for MFH depends on several factors, including the tumor's location, size, grade (degree of differentiation), and the patient's age and overall health.

Benign fibrous histiocytoma (BFH) is a common benign tumor of the skin and superficial soft tissues. It primarily affects middle-aged adults and is more prevalent in men than women. The exact cause of BFH is unknown, but it's thought to arise from dermal fibroblasts or histiocytes.

Medical Definition: Benign Fibrous Histiocytoma (BFH) is a benign, slowly growing, solitary cutaneous or subcutaneous nodular tumor predominantly composed of a mixture of fibroblastic and histiocytic-like cells. The tumor typically presents as a well-circumscribed, firm, dome-shaped papule or nodule, ranging in size from a few millimeters to several centimeters. Histologically, BFH is characterized by the proliferation of spindle-shaped fibroblasts and histiocytes arranged in a storiform pattern, along with variable amounts of collagen deposition, multinucleated giant cells, and hemosiderin deposits. The lesion usually has a pushing border with no invasion into the surrounding tissues. BFH generally follows a benign clinical course, with local recurrence being uncommon following complete surgical excision.
