Malignant ovarian tumours of the fibrothecoma group are rare. The clinicopathological features of a case of ovarian malignant fibrothecoma in which there was metastatic disease in the small intestine and peritoneum at presentation are described. A number of differential diagnoses were considered but positive immunohistochemical staining of the resected ovarian and small intestinal neoplasms wit...

Background: Ovarian epithelial tumors one of the most common gynecological neoplasms; we here evaluated the presence of HPV in benign and malignant examples. Methods: In this cross-sectional study the records of 105 patients with epithelial ovarian tumors (benign and malignant) referred to Imam Hossein University Hospital from 2012 to 2015 were evaluated along with assessment of the presence of...

Mature cystic teratomas, also known as dermoid cysts, are composed of a mixture of tissues derived from all three germ layers and constitute about 20% of all ovarian neoplasms. However, malignant transformation in a mature cystic teratoma is an uncommon event occurring only in about 1.8% cases. A variety of tumours can arise within a mature cystic teratoma (most common being squamous cell carci...

Contrast Enhanced microbubble Transvaginal Sonography (CE-TVS) can distinguish benign and malignant ovarian tumors. Initial results from several medical centers around the world have indicated that there are unique enhancement patterns in ovarian neoplasms. Challenges to the implementation of CE-TVS remain since some aggressive ovarian tumors (type 2) that arise in the tubal epithelium and meta...

Neuroendocrine carcinomas (NECs) are rare malignancies that originate from the hormone-producing cells of the body's neuroendocrine system. Rectal high grade NEC (HG-NEC) constituting less than 1% of colorectal cancers can cause large ovarian metastasis that may be the initial presenting complaint. Ovarian Krukenberg tumor from a primary rectal HG-NEC is a very unusual and exceedingly uncommon ...

In this issue, Koo and colleagues authored an interesting article entitled “An 11-year experience with ovarian surgery during pregnancy”. They investigated the characteristics and outcomes of pregnant women who underwent surgical intervention for ovarian neoplasm and found that either conventional laparotomy or laparoscopy approach could be successfully used in the management of ovarian tumor d...

fine- needle (fna) cytology of ovary is a simple method for evaluation of ovarian masses. but there is controversy about its reliability in differentiating between benign and malignant neoplasms. to evaluate the efficiacy of fna cytology in the distinction between benign and malignant masses of ovary, we examined 55 fine needle aspirations from 55 women 14-74 years of age. the aspirations were ...

Approximately one-fourth of the ovarian neoplasms and cysts are diagnosed incidentally during caesarean section. The possibility of borderline tumor or cancer should be considered although existence of ovarian malignancy in pregnancy is rare. We report a case of a rare solid malignant tumor of the ovary incidentally found during caesarean section. Intraoperatively, it was thought to be a varian...

An 80-year-old female presented with one month history of acutely worsening abdominal distention and pain, without features of bowel obstruction. A giant intra-abdominal simple cyst, separate from the ovaries, was seen on imaging. Initial haematological and biochemical investigations, including tumour markers, were normal. At laparotomy, the cystic tumour was discovered to arise from the sigmoi...
