Surgical removal of the vermiform appendix. (Dorland, 28th ed)
A condition characterized by poorly-circumscribed gelatinous masses filled with malignant mucin-secreting cells. Forty-five percent of pseudomyxomas arise from the ovary, usually in a mucinous cystadenocarcinoma (CYSTADENOCARCINOMA, MUCINOUS), which has prognostic significance. Pseudomyxoma peritonei must be differentiated from mucinous spillage into the peritoneum by a benign mucocele of the appendix. (Segen, Dictionary of Modern Medicine, 1992)
Acute inflammation of the APPENDIX. Acute appendicitis is classified as simple, gangrenous, or perforated.
A multilocular tumor with mucin secreting epithelium. They are most often found in the ovary, but are also found in the pancreas, appendix, and rarely, retroperitoneal and in the urinary bladder. They are considered to have low-grade malignant potential.

Carcinoid of the appendix during laparoscopic cholecystectomy: unexpected benefits. (1/160)

Carcinoid tumors of the midgut arise from the distal duodenum, jejunum, ileum, appendix, ascending and right transverse colon. The appendix and terminal ileum are the most common location. The majority of carcinoid tumors originate from neuroendocrine cells along the gastrointestinal tract, but they are also found in the lung, ovary, and biliary tracts. We report the first case of elective laparoscopic cholecystectomy in which we found a suspicious lesion at the tip of the appendix and proceeded to perform a laparoscopic appendectomy. The lesion revealed a carcinoid tumor of the appendix.  (+info)

Molecular genetic evidence supporting the clonality and appendiceal origin of Pseudomyxoma peritonei in women. (2/160)

Pseudomyxoma peritonei (PMP) is a poorly understood condition characterized by mucinous ascites and multifocal peritoneal mucinous tumors. Women with PMP often have mucinous tumors involving both the appendix and the ovaries. Several previous histopathological and immunohistochemical studies of PMP have suggested that most, if not all, cases of PMP in women are derived from mucinous adenomas of the appendix rather than from primary ovarian tumors. A few studies of the molecular genetics of PMP have been recently reported. However, these studies analyzed only a small number of cases and some included a heterogeneous group of mucinous tumors, including both benign and malignant appendiceal and ovarian tumors. We analyzed K-ras mutations and allelic losses of chromosomes 18q, 17p, 5q, and 6q in a substantial number of morphologically uniform cases of PMP with synchronous ovarian and appendiceal tumors as well as in appendiceal mucinous adenomas (MAs) and ovarian mucinous tumors of low malignant potential (MLMPs) unassociated with PMP. Each of the 16 PMP cases (100%) analyzed demonstrated identical K-ras mutations in the appendiceal adenoma and corresponding synchronous ovarian tumor. K-ras mutations were identified in 11 of 16 (69%) appendiceal MAs unassociated with PMP and in 12 of 16 (75%) ovarian MLMPs unassociated with PMP. Two PMP cases showed identical allelic losses in the matched ovarian and appendiceal tumors. A discordant pattern of allelic loss between the ovarian and appendiceal tumors at one or two of the loci tested was observed in six PMP cases. In all but one instance, LOH was observed in the ovarian tumor, whereas both alleles were retained in the matched appendiceal lesion, suggesting tumor progression in a secondary (metastatic) site. Our findings strongly support the conclusion that mucinous tumors involving the appendix and ovaries in women with PMP are clonal and derived from a single site, most likely the appendix.  (+info)

Morphological-histochemical study of intestinal carcinoids and K-ras mutation analysis in appendiceal carcinoids. (3/160)

Intestinal carcinoids are potentially malignant neoplasms. Their histogenesis and pathogenesis are currently uncertain. The morphological and histochemical characteristics of twenty intestinal carcinoids are studied. The primary sites of three mucin-producing tumors were examined by electron microscope. Furthermore 11 appendiceal carcinoids were analysed by the polymerase chain reaction (PCR) for the detection of ras and p53 point mutations. Microscopically all carcinoids were of mixed type. Focal mucin production was evident in three carcinoids that metastasised to regional lymph nodes. HID-Alcian blue staining proved that mucin in both primary and secondary foci did not belong to the sulphated group. The secretory granules and mucin droplets found in a single neoplastic cell suggest that carcinoids of the small intestine and some of the appendix arise from the endoderm. Neither ras nor p53 mutations were detected. It seems that ras oncogenes are probably not involved in the pathogenesis of appendiceal carcinoids.  (+info)

Malignant mesothelioma eight years after a diagnosis of atypical mesothelial hyperplasia. (4/160)

The separation of mesothelial hyperplasia from early malignant mesothelioma remains one of the most difficult problems in histopathology. Inconclusive cases are termed "atypical mesothelial hyperplasia" and treated expectantly. A 49 year old male pipeline engineer was diagnosed as having atypical mesothelial hyperplasia in appendiceal serosa by the US-Canadian Mesothelioma Panel. Eight years later, he developed overtly malignant peritoneal and pleural mesothelioma. In hindsight, histological similarities between the diffuse malignant mesothelioma and the atypical mesothelial proliferation suggested malignancy from the outset. The most important of these features were the degree of mesothelial proliferation, micronodularity, architectural complexity, superficial invasion, uniform mild cytological atypia, and the absence of a clinical cause for a benign mesothelial proliferation. Ancillary investigations including immunohistochemistry were of no benefit in determining whether the atypical mesothelial hyperplasia was benign or malignant. Careful histological examination remains the mainstay of the diagnosis of early mesothelioma.  (+info)

The coexistence of low-grade mucinous neoplasms of the appendix and appendiceal diverticula: a possible role in the pathogenesis of pseudomyxoma peritonei. (5/160)

We examined 38 appendectomies with diagnoses of mucocele, diverticulum, or adenoma to study the coincidence of appendiceal diverticula and appendiceal low-grade mucinous neoplasms and to examine the possible role of diverticula in the pathogenesis of pseudomyxoma peritonei. Invasive adenocarcinomas and retention cysts were excluded (six cases). Cases were classified as adenomas or mucinous tumors of unknown malignant potential, with or without diverticula. Medical records were reviewed for multiple parameters, including presenting symptoms, presence of pseudomyxoma peritonei, and presence of associated malignancies. Binomial statistics were used to calculate the probability that the observed prevalence of low-grade mucinous neoplasms and diverticula together was significantly different from the expected prevalence of diverticula or low-grade mucinous neoplasms alone, using historical controls from the literature. Twenty-five percent of the total cases (8 of 32) contained both a low-grade mucinous neoplasm (7 cystadenomas and 1 mucinous tumor of unknown malignant potential) and a diverticulum. Thus, 8 of 19 low-grade mucinous neoplasms (42%) were associated with diverticula. Of the appendices with both low-grade mucinous neoplasms and diverticula, three contained dissecting acellular mucin within the appendiceal wall, four showed diverticular perforation, and one had pseudomyxoma peritonei associated with the ruptured diverticulum. A significant percentage (P < .001) of cases contained low-grade mucinous neoplasms and diverticula together. The case of coexistent low-grade mucinous neoplasm, diverticulum, and pseudomyxoma peritonei suggests that diverticula could play a role in the pathogenesis of pseudomyxoma peritonei. This could occur either by involvement of preexisting diverticula by the neoplasm or by distention of the appendiceal lumen by mucin, leading to increased intraluminal pressure and subsequent diverticulum formation at a weak area in the wall. Either mechanism might allow low-grade mucinous neoplasms to penetrate the appendiceal wall more easily.  (+info)

Pyomyositis mimicking right iliac fossa mass: review of the literature. (6/160)

Pyomyositis is a pyogenic infection of skeletal muscle. Its incidence in temperate countries though low is rising. Most cases from the temperate region involve immuno-compromised patients. The onset is usually insidious with progression to large purulent collections. Because of its low incidence in temperate countries, it is often initially misdiagnosed. A high index of suspicion with appropriate imaging techniques, aggressive surgical intervention and adjunctive antibiotic therapy are the keys to prompt resolution. A case of pyomyositis mimicking right iliac fossa (RIF) mass is described with a review of the literature.  (+info)

Carcinoid syndrome symposium on treatment modalities for gastrointestinal carcinoid tumours: symposium summary. (7/160)

OBJECTIVE: To develop a collaborative approach for the treatment of gastrointestinal carcinoid tumours and carcinoid syndrome. PARTICIPANTS: Leaders in the medical, endocrine, radiologic and surgical treatment of carcinoid disease were selected to present papers at the Carcinoid Syndrome Symposium on Treatment Modalities for Gastrointestinal Carcinoid Tumours and participate in the workshop that followed. EVIDENCE: A multidisciplinary symposium with experts in the field of carcinoid syndrome was organized at the University of Calgary. Data presented, participation of the attendees and a review of the literature were used in the workshop to develop a collaborative approach to the management of carcinoid tumours. BENEFITS: Carcinoid tumours are rare and few centres have large experiences in their treatment. Before the development of this collaboration, patients with carcinoid tumours received a unidisciplinary approach depending on referral patterns. The development of a multidisciplinary neuroendocrine clinic helped to unify the approach to these patients, yet a consensus on the treatment of carcinoid tumours was lacking. The expertise at the symposium allowed for consensus and the development of treatment algorithms, including biochemical screening, radiographic localization and surgical intervention, for gastrointestinal carcinoid tumours. The role of medical and hormonal therapy after cytoreducion is presented. RECOMMENDATION: Patients with carcinoid tumours require a multidisciplinary approach to their care.  (+info)

Squamous cell carcinoma of the cervix metastasizing to the appendix is extremely rare and we previously unreported.  (+info)

Appendiceal neoplasms refer to various types of tumors that can develop in the appendix, a small tube-like structure attached to the large intestine. These neoplasms can be benign or malignant and can include:

1. Adenomas: These are benign tumors that arise from the glandular cells lining the appendix. They are usually slow-growing and may not cause any symptoms.
2. Carcinoids: These are neuroendocrine tumors that arise from the hormone-producing cells in the appendix. They are typically small and slow-growing, but some can be aggressive and spread to other parts of the body.
3. Mucinous neoplasms: These are tumors that produce mucin, a slippery substance that can cause the appendix to become distended and filled with mucus. They can be low-grade (less aggressive) or high-grade (more aggressive) and may spread to other parts of the abdomen.
4. Adenocarcinomas: These are malignant tumors that arise from the glandular cells lining the appendix. They are relatively rare but can be aggressive and spread to other parts of the body.
5. Pseudomyxoma peritonei: This is a condition in which mucin produced by an appendiceal neoplasm leaks into the abdominal cavity, causing a jelly-like accumulation of fluid and tissue. It can be caused by both benign and malignant tumors.

Treatment for appendiceal neoplasms depends on the type and stage of the tumor, as well as the patient's overall health. Treatment options may include surgery, chemotherapy, or radiation therapy.

The appendix is a small, tube-like structure that projects from the large intestine, located in the lower right quadrant of the abdomen. Its function in humans is not well understood and is often considered vestigial, meaning it no longer serves a necessary purpose. However, in some animals, the appendix plays a role in the immune system. Inflammation of the appendix, known as appendicitis, can cause severe abdominal pain and requires medical attention, often leading to surgical removal of the appendix (appendectomy).

Cecal diseases refer to medical conditions that affect the cecum, which is a pouch-like structure located at the junction of the small and large intestines. The cecum plays an important role in digestion, particularly in the fermentation of certain types of food.

There are several different types of cecal diseases, including:

1. Cecal volvulus: This is a rare condition in which the cecum twists on itself, cutting off blood flow and causing severe pain and other symptoms.
2. Diverticulitis: This occurs when small pouches called diverticula form in the wall of the cecum and become inflamed or infected.
3. Appendicitis: Although not strictly a cecal disease, the appendix is a small tube-like structure that branches off from the cecum. Inflammation of the appendix (appendicitis) can cause severe pain in the lower right abdomen and may require surgical removal of the appendix.
4. Crohn's disease: This is a chronic inflammatory bowel disease that can affect any part of the digestive tract, including the cecum.
5. Tuberculosis: The cecum can also be affected by tuberculosis, which is a bacterial infection that primarily affects the lungs but can spread to other parts of the body.
6. Cancer: Although rare, cancer can also affect the cecum, leading to symptoms such as abdominal pain, bloating, and changes in bowel habits.

Treatment for cecal diseases depends on the specific condition and its severity. Treatment options may include antibiotics, surgery, or other medical interventions. If you are experiencing symptoms that may be related to a cecal disease, it is important to seek medical attention promptly.

A mucocele is a mucus-containing cystic lesion that results from the accumulation of mucin within a damaged minor salivary gland duct or mucous gland. It is typically caused by trauma, injury, or blockage of the duct. Mucocele appears as a round, dome-shaped, fluid-filled swelling, which may be bluish or clear in color. They are most commonly found on the lower lip but can also occur on other areas of the oral cavity. Mucocele is generally painless unless it becomes secondarily infected; however, it can cause discomfort during speaking, chewing, or swallowing, and may affect aesthetics. Treatment usually involves surgical excision of the mucocele to prevent recurrence.

An appendectomy is a surgical procedure in which the vermiform appendix is removed. This procedure is performed when a patient has appendicitis, which is an inflammation of the appendix that can lead to serious complications such as peritonitis or sepsis if not treated promptly. The surgery can be done as an open procedure, in which a single incision is made in the lower right abdomen, or as a laparoscopic procedure, in which several small incisions are made and specialized instruments are used to remove the appendix. In some cases, if the appendix has burst, a more extensive surgery may be required to clean out the abdominal cavity.

Pseudomyxoma Peritonei (PMP) is a rare, slow-growing, and invasive cancer that typically starts in the appendix as a low-grade mucinous neoplasm, although it can also arise from other organs of the abdominal cavity. The primary characteristic of PMP is the accumulation of copious amounts of gelatinous ascites (peritoneal fluid containing mucin) within the peritoneal cavity, causing progressive abdominal distension and discomfort.

The condition is classified into three main histological subtypes: disseminated peritoneal adenomucinosis (DPAM), peritoneal mucinous carcinomatosis (PMCA), and hybrid tumors. DPAM is the least aggressive form, while PMCA is more invasive and has a worse prognosis.

The primary treatment for Pseudomyxoma Peritonei involves cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC). This approach aims to remove all visible tumors and destroy any remaining cancer cells within the abdominal cavity. Early diagnosis and aggressive treatment can significantly improve the prognosis for patients with PMP, although long-term survival rates remain variable due to the disease's rarity and heterogeneity.

Appendicitis is a medical condition characterized by inflammation of the appendix, a small finger-like structure that projects from the colon located in the lower right abdomen. The appendix doesn't have a known function, and its removal (appendectomy) does not appear to affect a person's health.

The inflammation of the appendix can be caused by various factors, such as obstruction due to hardened stool, foreign bodies, or tumors. The blockage can lead to increased pressure within the appendix, reduced blood flow, and bacterial growth, resulting in infection and inflammation. If left untreated, appendicitis can progress to peritonitis (inflammation of the lining of the abdominal cavity) or even sepsis, a life-threatening condition.

Common symptoms of appendicitis include:

* Sudden onset of pain in the lower right abdomen, which may start around the navel and shift to the lower right side over several hours
* Pain that worsens with movement, coughing, or sneezing
* Nausea and vomiting
* Loss of appetite
* Fever and chills
* Constipation or diarrhea
* Abdominal swelling or bloating

If you suspect appendicitis, it's essential to seek immediate medical attention. The standard treatment for appendicitis is surgical removal of the appendix (appendectomy), which can be performed as an open surgery or laparoscopically. Antibiotics are also administered to treat any existing infection. Delaying treatment can lead to serious complications, so it's crucial not to ignore symptoms and seek medical help promptly.

Mucinous cystadenoma is a type of benign tumor that arises from the epithelial cells lining the mucous membranes of the body. It is most commonly found in the ovary, but can also occur in other locations such as the pancreas or appendix.

Mucinous cystadenomas are characterized by the production of large amounts of mucin, a slippery, gel-like substance that accumulates inside the tumor and causes it to grow into a cystic mass. These tumors can vary in size, ranging from a few centimeters to over 20 centimeters in diameter.

While mucinous cystadenomas are generally benign, they have the potential to become cancerous (mucinous cystadenocarcinoma) if left untreated. Symptoms of mucinous cystadenoma may include abdominal pain or swelling, bloating, and changes in bowel movements or urinary habits. Treatment typically involves surgical removal of the tumor.
