What is adenocarcinoma ovary?
Ovarian clear cell adenocarcinomas (OCCAs) account for <5% of all ovarian malignancies. Compared to other epithelial ovarian cancer (EOC) subtypes, when at an advanced stage, they are associated with a poorer prognosis and are relatively resistant to conventional platinum‐based chemotherapy.
Can ovarian cancer spread to the appendix?
Ovarian cancer frequently spreads to the appendix, resulting in micrometastases. Metastatic ovarian cancer is a very rare cause of acute appendicitis. It is important to perform a thorough laparotomy in adult cases of acute appendicitis.
Why do they do appendectomy in ovarian cancer?
Appendectomy should be performed routinely, not only in mucinous, but also in nonmucinous epithelial ovarian cancers as a part of initial cytoreductive effort. The purpose of initial surgical treatment in epithelial ovarian cancers is correct detection of intraperitoneal and retroperitoneal metastatic involvement.
What is mucinous adenocarcinoma?
Mucinous adenocarcinomas (MACs) are a group of malignant tumors that originate from epithelial tissue and are characterized by abnormal mucus secretion.
Are tumors on the ovary usually cancerous?
Ovarian tumors are most often benign, however, some types may develop into ovarian cancer if left untreated. Symptoms are rare and tumors are usually detected during a routine pelvic exam or Pap test. Treatment typically involves surgical removal of the tumor and sometimes the surrounding tissue or the affected ovary.
What is mucinous adenocarcinoma of the appendix?
Mucinous adenocarcinoma: The second most common type of appendix cancer, mucinous adenocarcinomas begin in the appendix and produce mucin, a jelly-like substance that tends to spread cancerous cells to other parts of the body.
What are the features of metastatic mucinous ovarian carcinomas?
Clinicopathological parameters useful in the distinction of primary from metastatic mucinous ovarian carcinomas are reviewed. Major features favouring metastases are bilaterality, size <10 cm, surface involvement, extensive intra-abdominal spread and an extensive infiltrative pattern with desmoplasia.
Is there such a thing as an appendiceal mucinous neoplasm?
Appendiceal mucinous neoplasms (AMNs) are rare tumors accounting for less than 1% of all cancers. Appendiceal mucinous neoplasms include a heterogeneous group of diseases with varying malignant potential as reflected by different classification systems. Early stage AMNs are usually incidentally diagnosed at resection for suspicion of appendicitis.
What is the definition of metastatic adenocarcinoma?
Metastatic Appendix Mucinous Adenocarcinoma (Concept Id: C5207006) Mucinous adenocarcinoma of the appendix that has spread from the original site of growth to other anatomic sites. Metastatic Appendix Mucinous Adenocarcinoma
What kind of tumors are found in the appendix?
Malignant tumors of the appendix include mucinous epithelial neoplasms, neuroendocrine (typical carcinoid) tumors, goblet/ex‐goblet cell or composite carcinoid, lymphomas, adenocarcinomas, and lymphoid or mesenchymal sarcomas.
