primary ovarian carcinoid tumors of the ovary are rare and represent less than 0.1% of ovarian malignancy. one of its subtypes is the strumal carcinoid in which the thyroid tissue is seen in intimate association with carcinoid tumor. we here report a 47-year-old woman with strumal carcinoid of the right ovary presented with cessation of menstrual periods in the past 3 months and was referred du...

In women, >80% of malignant ovarian tumors are of epithelial origin. Early detection of these tumors is very challenging,and extensive i.p. dissemination is common by the time of diagnosis. The lack of adequate geneticmouse models of ovarian carcinomas significantly delays advances in early detection and treatment. We report that female transgenic mice expressing the transforming region of SV40...

BACKGROUND Meigs' syndrome is defined as the co-existence of benign ovarian fibroma or fibroma-like tumor, ascites, and pleural effusion. In contrast, pseudo-Meigs' syndrome is defined as the co-existence of other ovarian or pelvic tumors, ascites, and pleural effusion. In Meigs' and pseudo-Meigs' syndromes, ascites and pleural effusion resolve promptly after the complete resection of the ovari...

BACKGROUND Low-grade appendiceal mucinous neoplasms (LAMNs) are cytologically low-grade tumors of the appendix and are a frequent cause of pseudomyxoma peritonei. They can become a diagnostic challenge when they metastasize to the ovaries, where they may mimic primary ovarian mucinous tumors. CASE REPORT We report the case of a patient with very large bilateral ovarian mucinous tumors and a con...

Carcino-sarcoma is a malignant mixed mesodermal neoplasm accounting for less than 1% of all ovarian tumors. It an aggressive tumor, composed both epithelial and mesenchymal components. To the best our knowledge, 400 cases carcino-sarcomas have been reported in literature only 10% them are bilateral. In this paper, we report new case unilateral carcino-sarcoma 20-year-old adolescent girl with ai...

BACKGROUND Peritoneal dissemination of ovarian tumors is a major prognostic parameter in ovarian malignancies. Analysis of peritoneal washing cytology serves as a useful predictor of ovarian surface involvement and peritoneal metastasis even in the absence of clinical omental spread. The aim of the current study is to correlate peritoneal cytology with various histologic features of ovarian can...

Primary ovarian lymphoma is a rare malignancy whose symptoms or signs are usually nonspecific. In this article, we report a very rare case initially presenting as a rectal submucosal-tumor-like lesion with a defecation disturbance caused by primary ovarian lymphoma with bilateral involvement. A 42-year-old woman visited chungnam national university hospital complaining of persistent defecation ...

 Background: Ovarian masses represent a range of pathology from benign cyst to highly aggressive malignant tumors. It has been estimated that gynecologic malignancy account for approximately 2% of all types of cancer in children, 60-70% of these lesions arise in the ovary.  Methods: All ovarian masses which were resected or biopsied in Mofid Children's Hospital from 2002 to 2012 were reviewe...

Steroid cell tumor not otherwise specified (NOS) is a rare subtype of sex cord stromal tumor of the ovary and contributes less than 0.1% of all ovarian neoplasms. The majority of tumors occur in pre-menopausal women (mean age: 43 years), in which 56-77% of patients present with virilization due to excess testosterone. An 80-year-old woman with worsening alopecia and excessive growth of coarse h...

Approximately 6-7% of all adnexal masses found during physical examination are actually metastatic ovarian tumors, which often masquerades as the primary ovarian tumor. The circumstances leading to the discovery of these metastatic lesions depends on the site of the primary tumor. The ovaries may be only slightly enlarged or measure 10 cm or more. Ovarian metastases are bilateral in approximate...
