A benign tumor containing vascular, adipose, and muscle elements. It occurs most often in the kidney with smooth muscle elements (angiolipoleiomyoma) in association with tuberous sclerosis. (Dorland, 27th ed)
Autosomal dominant neurocutaneous syndrome classically characterized by MENTAL RETARDATION; EPILEPSY; and skin lesions (e.g., adenoma sebaceum and hypomelanotic macules). There is, however, considerable heterogeneity in the neurologic manifestations. It is also associated with cortical tuber and HAMARTOMAS formation throughout the body, especially the heart, kidneys, and eyes. Mutations in two loci TSC1 and TSC2 that encode hamartin and tuberin, respectively, are associated with the disease.
A disease characterized by the progressive invasion of SMOOTH MUSCLE CELLS into the LYMPHATIC VESSELS, and the BLOOD VESSELS. The majority of the cases occur in the LUNGS of women of child-bearing age, eventually blocking the flow of air, blood, and lymph. The common symptom is shortness of breath (DYSPNEA).
Tumors or cancers of the KIDNEY.
Characteristic cells of granulomatous hypersensitivity. They appear as large, flattened cells with increased endoplasmic reticulum. They are believed to be activated macrophages that have differentiated as a result of prolonged antigenic stimulation. Further differentiation or fusion of epithelioid cells is thought to produce multinucleated giant cells (GIANT CELLS).
A benign neoplasm composed of a mixture of adipose tissue and blood vessels. (Dorland, 27th ed)
Cellular antigens that are specific for MELANOMA cells.
A benign tumor composed of fat cells (ADIPOCYTES). It can be surrounded by a thin layer of connective tissue (encapsulated), or diffuse without the capsule.
Neoplasms composed of fatty tissue or connective tissue made up of fat cells in a meshwork of areolar tissue. The concept does not refer to neoplasms located in adipose tissue.
A usually benign glandular tumor composed of oxyphil cells, large cells with small irregular nuclei and dense acidophilic granules due to the presence of abundant MITOCHONDRIA. Oxyphil cells, also known as oncocytes, are found in oncocytomas of the kidney, salivary glands, and endocrine glands. In the thyroid gland, oxyphil cells are known as Hurthle cells and Askanazy cells.
Pain emanating from below the RIBS and above the ILIUM.
A vascular anomaly due to proliferation of BLOOD VESSELS that forms a tumor-like mass. The common types involve CAPILLARIES and VEINS. It can occur anywhere in the body but is most frequently noticed in the SKIN and SUBCUTANEOUS TISSUE. (from Stedman, 27th ed, 2000)

Differentiation of small hyperechoic renal cell carcinoma from angiomyolipoma: computer-aided tissue echo quantification. (1/177)

To assess the value of computer-aided tissue echo quantification in differentiating small hyperechoic renal cell carcinomas from angiomyolipomas, we studied ultrasonographic images of 15 renal cell carcinomas and 20 angiomyolipomas. After digitizing the images, we measured the absolute gray scale values of the renal cortex, central echo complex, and mass. The relative gray scale value (%) of the mass was calculated by setting the gray scale value of the cortex as 0% and the central echo complex as 100%. The relative gray scale value of renal cell carcinomas was in the range of 12 to 73% (mean, 28%), whereas that of angiomyolipomas was 30 to 204% (mean, 130%). The differentiation between small hyperechoic renal cell carcinomas and angiomyolipomas can be facilitated by computer-aided tissue echo quantification.  (+info)

Tuberous sclerosis associated with multiple hepatic lipomatous tumors and hemorrhagic renal angiomyolipoma. (2/177)

We report a case of tuberous sclerosis associated with hepatic lipomatous tumors and renal angiomyolipomas. Abdominal ultrasonography revealed a high echoic large tumor in the left kidney. A provisional diagnosis of angiomyolipomas of the kidney was made based on computed tomography. Subsequent laparotomy revealed that the extracted tumor was renal angiomyolipoma. It was also revealed that there was an association with hepatic lipomatous tumors thought to be lipomas or angiomyolipomas by liver biopsy. Nearly half of all cases of angiomyolipoma in the kidney are reported as occasional association with tuberous sclerosis complex, but lipomatous tumors in the liver are rare.  (+info)

Angiomyolipoma of the liver--a case report and review of 48 cases reported in Japan. (3/177)

Hepatic angiomyolipoma was considered to be a rare benign tumor, but the number of cases has been increasing recently as imaging techniques improve. We describe a case of hepatic angiomyolipoma for which a definitive diagnosis could not be made on imagings and in which resection was performed. The patient had anti-HCV antibody and slight dysfunction of the liver. The tumor showed a heterogeneous high echo on ultrasonography and a low attenuation value of +32.6 Housfield Units, which was much higher than fat density, on plain computed tomography. Discrimination from hepatocellular carcinoma with fatty change was difficult preoperatively. Microscopically, the tumor consisted of spindle-shaped and epithelioid smooth muscles, adipose tissues and proliferating blood vessels and these histological findings confirmed the diagnosis of hepatic angiomyolipoma. The appearance of hepatic angiomyolipoma on imaging diagnosis varies widely due to the fact that the relative proportion of vessels, muscles and fats varies widely from tumor to tumor. The tumor in our case had relatively few fat components. We review 48 cases reported in Japan and discuss imaging diagnosis and surgical indications for tumors.  (+info)

Renal function after tumor enucleation: assessment by quantitative SPECT of 99mTc-dimercaptosuccinic acid uptake by the kidneys. (4/177)

The purpose of this study was to evaluate the amount of functioning renal mass removed and the amount of remaining individual renal function after tumor enucleation. METHODS: Renal functional volume, percentage injected dose (%ID) per cubic centimeter of renal tissue and individual renal uptake of 24 operated and 24 contralateral kidneys were studied by two sequential SPECT quantitations of 99mTc-dimercaptosuccinic acid (DMSA) uptake by the kidneys (QDMSA). The first study was before surgery and the second study was 1 to 6 mo (mean 3.5 mo) after surgery. Mean tumor size was 3.4 +/- 0.99 cm and all tumors were confined to the renal parenchyma (stages pT1 and pT2). RESULTS: In the operated kidneys, there was a statistically significant decrease in renal cortical volume (170 +/- 46 mL after surgery versus 207 +/- 45 mL before surgery, t = 6.2, P < 0.001) and individual renal uptake (10.3% +/- 3.0% after surgery versus 13.0% +/- 2.9% before surgery, t = 5.4, P < 0.001). There was no statistically significant change after surgery compared with before surgery in the %ID per cubic centimeter of renal tissue of the operated kidneys, and in the volume, %ID per cubic centimeter and uptake of the contralateral normal kidneys. CONCLUSION: The results suggest that QDMSA is a noninvasive method able to assess changes in separate renal function. The limited functioning parenchymal loss after tumor enucleation had no effect on the opposite kidneys.  (+info)

Trabecular angiomyolipoma mimicking hepatic cell carcinoma. (5/177)

Hepatic angiomyolipomas are rare tumors, especially in comparison with those occurring in the kidney. Nevertheless, it is important to be aware of their existence, especially when occurring in the liver, where they might have different subtypes. Not infrequently they are composed of rather irregular cells with epithelioid appearance. In these cases hepatocellular carcinoma or the possibility of other malignant tumors has to be ruled out, with the aid of numerous immunohistochemical reactions. The authors present a case of a female patient, whose liver lesion was first diagnosed on cytological examination as a hepatocellular carcinoma. Based on the preoperative cytological diagnosis, a large liver lobe resection was performed. Histological examination found an angiomyolipoma of the above-mentioned type, and the final diagnosis was ascertained with the aid of vimentin, smooth muscle actin (SMA), and HMB-45.  (+info)

Concurrent angiomyolipoma and renal cell neoplasia: a study of 36 cases. (6/177)

Little is known about the association of angiomyolipoma and adult renal-cell neoplasia. We studied the clinicopathologic features of 36 patients with concurrent angiomyolipoma and renal-cell neoplasia from the consultation and surgical pathology files of nine institutions. HMB-45 immunoreactivity was analyzed in both neoplasms. Twenty-five sporadic cases of patients with angiomyolipoma and renal-cell neoplasia and 11 cases of patients with tuberous sclerosis, as defined by Gomez' criteria, had mean ages of 59 and 53 years, respectively, and female-male ratios of 2:1 and 5:1, respectively. The mean size of the angiomyolipomas was 1 cm in the sporadic cases and 3 cm in those patients with tuberous sclerosis (medians: 0.5 and 3 cm, respectively, P =.002). The mean sizes of the renal-cell neoplasms were 5 cm in sporadic cases and 6 cm in patients with tuberous sclerosis (medians: 4 and 5 cm, respectively; P =.88). In both clinical settings, angiomyolipoma was more commonly the incidental tumor. Clear-cell (conventional) renal-cell carcinoma was the most common renal-cell neoplasm in both groups of patients, accounting for approximately two thirds of the tumors. In patients with tuberous sclerosis, 27% of renal-cell neoplasms were oncocytomas, compared with 8% in sporadic cases (P =.15). Papillary neoplasia, chromophobe, and collecting-duct renal-cell carcinoma were found only in sporadic cases. All of the 22 renal-cell neoplasms studied were negative for HMB-45, whereas all 25 angiomyolipomas studied were positive.  (+info)

Unilateral concurrence of pyelocaliceal diverticula and intracapsular angiomyolipoma in the kidney of a cat. (7/177)

A 7-month-old cat was examined for progressive abdominal distension. Radiography showed a fluid-containing cyst, which had subsequently ruptured as the result of a fall. Nephrectomy was performed, and examination revealed the coexistence of pyelocaliceal diverticula with a cystic intracapsular angiomyolipoma (mesenchymal hamartoma) in the left kidney. The diverticula were present on both cranial and caudal poles of the kidney and were lined by transitional epithelium. The hamartoma was characterized by the presence of multiple mesenchymal tissues, including thick-walled blood vessels, smooth muscle, and adipose tissue.  (+info)

A case of retroperitoneal lipoleiomyoma. (8/177)

We report a case of lipoleiomyoma which arose in retroperitoneum and presented with progressively distended abdomen in a 56-yr-old woman. The tumor was well encapsulated and consisted of two components, benign smooth muscle cells and mature adipose tissue without any atypia. It is likely to be mistaken as extrarenal angiomyolipoma, well-differentiated liposarcoma and leiomyoma with fatty change. We review the histologic characteristics of previously reported myolipoma and describe essential points of differential diagnosis.  (+info)

Angiomyolipomas are the most common benign tumour of the kidney. Although regarded as benign, angiomyolipomas may grow such that kidney function is impaired or the blood vessels may dilate and burst leading to bleeding. Angiomyolipomas are strongly associated with the genetic disease tuberous sclerosis, in which most individuals will have several angiomyolipomas affecting both kidneys. They are also commonly found in women with the rare lung disease lymphangioleiomyomatosis. Angiomyolipomas are less commonly found in the liver and rarely in other organs. Whether associated with these diseases or sporadic, angiomyolipomas are caused by mutations in either the TSC1 or TSC2 genes, which govern cell growth and proliferation. They are composed of blood vessels, smooth muscle cells and fat cells. Large angiomyolipoma can be treated with embolisation. Drug therapy for angiomyolipoma is at the research stage. The Tuberous Sclerosis Alliance has published guidelines on diagnosis, surveillance and ...

A 51-year-old female had been diagnosed with a hemangioma in the hepatic segment 6 (S6). After a 6-year follow-up, enlargement of the tumor was detected. The tumor was clearly enhanced in the arterial phase, and the enhancement remained in the portal phase on computed tomography (CT). Although the primary differential diagnosis on CT was hepatocellular carcinoma (HCC), we worried about the possibility of other vessel system tumors because the tumor remained to be enhanced at the portal phase for HCC and all tumor markers of HCC were negative. We performed angiography to determine the tumor nature and to seek other tumors. Angiography showed tumor stain at the hepatic S6 with an early obvious drainage vein from the tumor flowing through the right hepatic vein into the inferior vena cava. In addition to tumor stain and the drainage vein, there were many small poolings of contrast medium in the whole liver, which were suspected as dilatation of the hepatic peripheral artery. We suspected the tumor as a
The family of tumors derived from mesenchymal perivascular epithelioid cells (so-called PEComas) includes angiomyolipoma, lymphangioleiomyomatosis, clear cell sugar tumor of the lung, clear cell myomelanocytic tumor of ligamentum teres/falciform ligament, and abdominopelvic sarcoma of perivascular epithelioid cells.. These tumors were characterized by coexpression of melanocytic (HMB-45) and muscle markers. MyoD1 transcription factor has crucial role in commitment and differentiation of mesenchymal progenitor cells to myogenic lineage. Antibodies to MyoD1 protein (nuclear immunoreactivity) have been shown highly valuable adjuncts in the diagnosis of rhabdomyosarcomas.. To evaluate expression of the transcription factor MyoD1 in PEComas, we performed immunohistochemistry. Monoclonal antibody 5.8A for MyoD1 was used on a series of cases of formalin-fixed, paraffin-embedded angiomyolipoma (n = 19), lymphangioleiomyomatosis (n = 3), clear cell sugar tumor of the lung (n = 1), and abdominopelvic ...

OBJECTIVES: We examined the long-term effects of everolimus in patients with renal angiomyolipoma associated with tuberous sclerosis complex or sporadic lymphangioleiomyomatosis. METHODS: Following favorable results from the double-blind core phase of EXIST-2 (NCT00790400), patients were allowed to receive open-label everolimus (extension phase). Patients initially randomly assigned to everolimus continued on the same dose; those who were receiving placebo crossed over to everolimus 10 mg/day. Dose modifications were based on tolerability. The primary end point was angiomyolipoma response rate, defined as a ≥50% reduction from baseline in the sum volume of target renal angiomyolipomas in the absence of new target angiomyolipomas, kidney volume increase of >20% from nadir, and angiomyolipoma-related bleeding grade ≥2. The key secondary end point was safety. RESULTS: Of the 112 patients who received ≥1 dose of everolimus, 58% (95% CI, 48.3% to 67.3%) achieved angiomyolipoma response. Almost ...

Abstract Though rare, angiomyolipomas (AMLs) are the most common mesenchymal tumors of kidney. In general, AMLs can always be associated with two conditions affecting other organ systems: tuberous sclerosis complex (TSC) and sporadic lymphangioleiomyomatosis. This article presents a case of renal AML occurring in a 14-year-old girl with a definite diagnosis of TSC. She had been diagnosed with TSC at the age of three, and a schedule for close observation was disobeyed. At this time, she underwent a series of examinations: physical examination, ultrasonography, angiography, computed tomography (CT), and magnetic resonance imaging (MRI) scans. The physical examination showed adenoma sebaceum in a butterfly paranasal distribution, and a mass was palpated in the left upper quadrant. There were no neurological deficits. Imaging studies (including ultrasonography, angiography, CT, and MRI) of the abdomen showed a large heterogeneous mass arising from the left kidney. Partial nephrectomy was performed. ...
Gross findings of hepatic EAMLs are usually reported as tan colored nodule with variegated appearance, because of intra-tumoral hemorrhage, adipose component, and in sometimes, necrosis. Microscopic findings of hepatic EAML is characterized by epithelioid tumor cells with plump eosinophilic granular cytoplasm arranged around blood vessesls. Those cells usually show round to polygonal cytoplasm and round and large nucleus with prominent nuclei. In some cases, tumor cells show clear cytoplasm rather than eosinophilic cytoplasm. The adipose component may be scanty or absent. The multinucleated giant cells and large ganglion like tumor cells were common. Usually, mitotic figures of tumor cell is rarely observed. The predominance of epithelioid cell is the most important factor for the diagnosis of EAML. There is still a debate on the cut-off ratio of epithelioid cells needed for the diagnosis of EAML [11]. The immunohistochemical staining is important in the diagnosis of EAML. It is well-known that ...

Summary: Background. Renal angiomyolipoma is a benign mezenchymal tumour with prevalence of 0,3-3 % of all surgically resected renal tumours. Tumour is often associated with tuberous sclerosis complex or with another fakomatosis. Tumour has typical pathological image in computer tomography notation that enables the diagnosis. Symptomatology and possible complications depend on the tumour size. Large or symptomatic tumours are indicated for resection, nephrectomy or local ablation. Methods and Results. 612 patients with renal tumour were operated at the Department of Urology faculty hospital in Pilsen. Angiomyolipoma occurred in 7 patients. Average age at the time of operation was 64 years, ratio female and male was 5:2. Clinical symptomatology was expressed in 3 patients. The size of tumour was 2 to 8 cm, in 5 patient the tumors were solitary. Translumbal tumour resection was performed in 3 patients. These tumours were at the same time multifocal. Suspicion from tuberous sclerosis was pronounced ...
The peculiar histology of AML has been the subject of much investigation. While previously hypothesized to represent a hamartoma, later studies disclosed the clonal nature of AML (Kattar et al, 1999). It is currently accepted that renal AML results from aberrant differentiation of a transformed renal progenitor (Folpe & Kwiatkowski, 2010). Accordingly, two key questions surround AML biology. First, which molecular mechanisms drive its development and growth? Second, what is the AML cell of origin? Unfortunately, the study of AML, the leading cause of death in TSC, is severely limited by the absence of an in vivo model, thereby hampering the development of new therapies. Most studies attempting to develop such a model relied on TSC1/2‐deficient rodents (Kobayashi et al, 1995, 1999, 2001; Liang et al, 2014). However, none has resulted in tumors exhibiting the full histological features of genuine AML. Via serial propagation of human AML cells in mice, we provide the first description of such a ...
PEDEMONTE, J.G. et al. Angiomyolipoma and lenk syndrome: case report. Actas Urol Esp [online]. 2008, vol.32, n.8, pp.850-854. ISSN 0210-4806.. Angiomyolipoma (AML) is a benign clonal neoplasm that consists of varying amounts of mature adipose tissue, smooth muscle, and thick-walled vessels. Approximately 20% of AMLs are found in patients with tuberous sclerosis syndrome (TS), an autosomal-dominant disorder characterized by mental retardation, epilepsy, and adenoma sebaceous, a distinctive skin lesion. Massive retroperitoneal hemorrhage from AML, also known as Wunderlichs syndrome, has been found in up to 10% of patients and represents the most significant and feared complication. The presence of even a small amount of fat within a renal lesion on CT scan (confirmed by Hounsfield unit s ≤10) is considered diagnostic of AML. Intervention should be considered for larger tumors, particularly if the patient is symptomatic, taking into account patient age, comorbidities, and other related factors. ...

Our data present that is clearly a detrimental regulator of BM-MSC proliferation and support a pivotal function for the Tsc1-mTOR axis in the maintenance of the mesenchymal progenitor pool. (encoding hamartin) or (encoding tuberin) causes tuberous sclerosis (TSC), a multisystemic, autosomal prominent disorder with around prevalence of just one 1 in 6000 newborns. TSC is normally characterized by harmless, focal malformations known as hamartomas, which comprise nonmalignant cells exhibiting unusual cell differentiation and proliferation [1,2]. TSC causes disabling neurological disorders frequently, including epilepsy, mental retardation, and autism. Various other major top features of this symptoms include several manifestations of mesenchymal origins such as for example (1) renal angiomyolipomas [3], harmless tumors made up of ...
The ultrasound images of RCC is a (usually) large, heterogeneous mass which enlarges and deforms the shape of the kidney (Fig. below). The mass may contain areas of cystic degeneration and/or calcification. It has a predilection to spread into the ipsilateral renal vein and IVC (see also Chapter 8). olour Doppler usually reveals a disorganized and increased blood flow pattern within the mass with high velocities from the arterioverous shunts within the carcinoma. Smaller RCCs can be hyperechoic and may be confused with benign angiomyolipoma. The latter has well-defined borders whilst an RCC is illdefined: differentiation may not be possible on all occasions and biopsy or interval scan may be required. A chest X-ray and/or CT will demonstrate if metastases are present in the lungs. Liver, adrenal and lymph node metastases can be demonstrated on ultrasound but CT is used for staging purposes as ultrasound generally has a lower sensitivity for distant disease detection ...

In this paper, exact closed-form solutions for displacement and stress components of thick-walled functionally graded (FG) spherical pressure vessels are presented. To this aim, linear variation of properties, as an important case of the known power-law function model is used to describe the FG material distribution in thickness direction. Unlike the pervious studies, the vessels can have arbitrary inner to outer stiffness ratio without changing the function variation of FGM. After that, a closed-form solution is presented for displacement and stress components based on exponential model for variation of properties in radial direction. The accuracy of the present analyses is verified with known results. Finally, the effects of non-homogeneity and different values of inner to outer stiffness ratios on the displacement and stress distribution are discussed in detail. It can be seen that for FG vessels subjected to internal pressure, the variation of radial stress in radial direction becomes linear as the

The benign, non-invasive lesions of tuberous sclerosis can appear in any organ like the brain, heart, skin, eyes, kidney, lung, and liver. Therefore, TS has a wide clinical spectrum. The diagnosis of definitive TS is based on specific clinical features and requires the presence of two major criteria, or one major and two minor [3]. Pulmonary lymphangioleiomyomatosis, renal angiomyolipoma and facial angiofibroma are some of the major clinical features.. The most frequent cause of death in patients with TS is renal complication [3, 5]. Multifocal, bilateral angiomyolipomas are found in about 70-90% of adult patients [3], and the prevalence increases with age, being less frequent in children [3, 4]. These lesions are more often prevalent in women, suggesting a hormonal component to the tumor growth [6]. The angiomyolipomas are composed of varying amounts of mature adipose tissue, smooth muscle, and abnormal blood vessels [3, 6].

Our patient also had stigmata of tuberous sclerosis complex (TSC), including facial angiofibromas and renal angiomyolipoma. Immunohistochemical stains of both Lam and renal angiomyolipoma showed positive immunoreactivity for hamartin (TSC1) and loss of immunoreactivity for tuberin (TSC2). Loss of heterozygosity (LOH) for TSC2 was further demonstrated in the renal angiomyolipoma. Coupled with the results of immunostains, these findings are consistent with TSC2 mutation..

LAM also occurs in patients who do not have TSC. This form, termed sporadic LAM or S-LAM, is diagnosed in at least 2.5-5 per million women, or roughly 10,000 women worldwide, although it is likely that S-LAM is substantially underdiagnosed. To date, only one biopsy-documented case of S-LAM in a male has been reported. Although less common, most patients seen in the clinic have S-LAM rather than TSC-LAM.. In LAM, lung destruction occurs as a result of neoplastic proliferation of benign-appearing smooth muscle cells in the lung. Genetic evidence indicates that the LAM cells that infiltrate the lung arise from an unknown extrapulmonary source and spread via the bloodstream and lymphatics. Leading candidates for the site of origin include the uterus, renal angiomyolipomas, and lymphatics. LAM cells express the lymphangiogenic growth factors VEGF-C and VEGF-D and induce disordered lymphatic channel formation in the lung and lymphatics. Frustrated lymphangiogenesis likely contributes to the ...

Tuberous sclerosis complex (TSC) is highly variable in clinical presentation and findings. Disease manifestations continue to develop over the lifetime of an affected individual. Accurate diagnosis is fundamental to implementation of appropriate medical surveillance and treatment. Updated Diagnostic Criteria for Tuberous Sclerosis Complex.. A. Genetic diagnostic criteria. The identification of either a TSC1 or TSC2 pathogenic mutation in DNA from normal tissue is sufficient to make a definite diagnosis of tuberous sclerosis complex (TSC). A pathogenic mutation is defined as a mutation that clearly inactivates the function of the TSC1 or TSC2 proteins (e.g., out-of-frame indel or nonsense mutation), prevents protein synthesis (e.g., large genomic deletion), or is a missense mutation whose effect on protein function has been established by functional assessment. Other TSC1 or TSC2 variants whose effect on function is less certain do not meet these criteria, and are not sufficient to make a ...
Tuberous sclerosis complex is caused by inactivating mutations in TSC1 (hamartin) or TSC2 (tuberin) tumor suppressor genes. The disorder is associated with increased activity of mammalian target of rapamycin (mTOR), a central regulator of protein synthesis and cell growth that is inhibited by chronic oxygen deprivation (hypoxia). Tumor hypoxia has been associated with a negative prognosis in several types of cancers. With funding from a Department of Defense Tuberous Sclerosis Complex Research Program Fiscal Year 2003 Idea Development Award, Dr. William Kaelin of the Dana-Farber Cancer Institute has discovered that the TSC1/TSC2 protein complex regulates mTOR in response to hypoxia. Dr. Kaelin and his research team showed that an intact TSC1/TSC2 complex is required for mTOR inhibition by hypoxia. Inactivation of TSC2 conferred a proliferative advantage to cells grown under hypoxic conditions. Dr. Kaelins group further defined the mechanisms of TSC1/TSC2-mediated mTOR inhibition under hypoxic ...

Ultrasound (US) scan showed bilateral renal masses. CT scan of the abdomen revealed mass lesions in both kidneys (Fig. 1 D). The lesions showed no fat attenuation, with areas of necrosis and calcifications suggestive of bilateral renal cell carcinoma. The parents refused further evaluation and treatment.. Discussion. Tuberous sclerosis complex (TSC) is an extremely variable genetic disorder that can affect virtually any organ in the body. The most common findings are benign tumours in the skin, brain, kidneys, lungs and heart, which can lead to organ dysfunction. TSC is highly variable in clinical presentation and findings. Diagnosis is made based on the updated diagnostic criteria established at the Tuberous Sclerosis Complex Consensus Conference in 2012. Disease manifestations continue to develop over the lifetime of an affected individual. Accurate diagnosis is fundamental to implementation of appropriate medical surveillance and treatment, apart from being crucial for optimal quality of life ...

Y1 - 2015/12/1. N2 - Tuberous sclerosis complex (TSC) is an autosomal dominant disorder characterized by the development of widespread hamartomatous lesions in various organs, including brain, skin, kidneys, heart, and eyes. Central nervous system is almost invariably involved, with up to 85% of patients presenting with epilepsy, and at least half of patients having intellectual disability or other neuropsychiatric disorders including autism spectrum disorder. TSC is caused by the mutation in one of the 2 genes TSC1, at 9q34, and TSC2, at 16p13.3. They respectively encode for hamartin and tuberin, which form an intracellular complex inhibiting the mammalian target of rapamycin. Mammalian target of rapamycin overactivation following the genetic defect determines the cell growth and proliferation responsible for ...

Tuberous sclerosis complex (TSC) is an autosomal dominant disease caused by mutations in either the TSC1 (encodes hamartin) or TSC2 (encodes tuberin) genes. Patients with TSC have hamartomas in various organs throughout the whole body, most notably in the brain, skin, eye, heart, kidney and lung. To study the development of hamartomas, we generated a zebrafish model of TSC featuring a nonsense mutation (vu242) in the tsc2 gene. This tsc2vu242 allele encodes a truncated Tuberin protein lacking the GAP domain, which is required for inhibition of Rheb and of the TOR kinase within TORC1. We show that tsc2vu242 is a recessive larval-lethal mutation that causes increased cell size in the brain and liver. Greatly elevated TORC1 signaling is observed in tsc2vu242/vu242 homozygous zebrafish, and is moderately increased in tsc2vu242/+ heterozygotes. Forebrain neurons are poorly organized in tsc2vu242/vu242 homozygous mutants, which have extensive gray and white matter disorganization and ectopically ...
Advanced Research on Information Science, Automation and Material System: Numerical Study of Welding Sequence on the Residual Stress Field in a Thick-Walled Tee Joint
Tuberous sclerosis complex (TSC) is a genetic disorder characterized by seizures, mental disability, renal dysfunction and dermatological abnormalities. The disease is caused by inactivation of either hamartin or tuberin, the products of the TSC1 and TSC2 tumour-suppressor genes. Hamartin and tuberin form a complex and antagonise phosphoinositide 3-kinase/protein kinase B/target of rapamycin signal transduction by inhibiting p70 S6 kinase, an activator of translation, and activating 4E-binding protein 1, an inhibitor of translation initiation. Phosphorylation-dependent binding between tuberin and members of the 14-3-3 protein family indicates how the tuberin-hamartin complex may interact with upstream and downstream effectors, and suggests how phosphorylation-dependent regulation of the complex may be controlled.. ...

Thin does not always = healthy. My family always joked I had to eat every hour or two and was easily hangry. We thought it was funny I had to eat so much food during the day and always have snacks on me. I would get nauseous, light headed or headaches if I didnt eat on time or had to wait a little longer between meals. It was actually quite a pain because most of my life revolved around food, if I wasnt eating I was thinking about my next meal or getting a snack ready.
