• mitotically active cellular fibroma
  13 July 2018

  mitotically active cellular fibroma of the ovary. MACF
  The ovarian cellular fibrous tumor with mitotic figure >4 per 10 high power field without moderate to severe atypia is defined as mitotically active cellular fibroma according to the 2014 World Health Organization classification.
  As this category is new and rare now, we described here a case of MACF and reviewed the literature.
  MACF of the ovary is a newly defined category and few cases have been reported, while prognostic factors (...)

• ovarian borderline serous cystadenofibroma
  10 March 2018

  Serous Cystadenofibroma, Borderline of the ovary
  Definition: Benign serous ovarian tumors with a prominent fibroblastic stromal component are called serous cystadenofibromas. Usually, there is abundant spindle cell stroma in several papillary structures. In addition, many papillary structures can show hierarchical branching from larger to progressively smaller papillae, accounting for the " borderline " designation.

• membrana granulosa
  29 December 2017

  WP
  The larger ovarian follicles consist of an external fibrovascular coat, connected with the surrounding stroma of the ovary by a network of bloodvessels; and an internal coat, which consists of several layers of nucleated cells, called the membrana granulosa. It contains numerous granulosa cells.
  At one part of the mature follicle the cells of the membrana granulosa are collected into a mass which projects into the cavity of the follicle. This is termed the discus proligerus.

• ovarian papillary tumors
  11 May 2017

  Examples
  ovarian papillary serous carcinoma / ovarian serous carcinoma Ovarian papillary serous carcinoma has fibrovascular papillae that are typically not hyalinized. There is cellular tufting and budding. Mitoses are more common than clear cell adenocarcinoma, and there is not hobnailing. It is high grade (pleomorphic with nucleoli), or low grade (uniform cells +/- nucleoli). IHC is positive for p16, ER, WT-1, IMP3, and p53.

  Examples
  ovarian gonadoblastoma
  Gonadoblastoma has ovarian stroma surrounding nests of germ cells and sex cord stromal cells, with frequent hyalinization and calcification.
  It is the most frequent tumor found in gonadal dysgenesis, usually a phenotypic female with an XY karyotype and streak gonads.

• ovarian spindle cell tumors
  11 May 2017

  Examples
  ovarian fibroma Ovarian fibroma has dense benign spindle cells. It is associated with Meigs syndrome (ovarian fibroma, ascites, right pleural effusion), and Gorlin syndrome (basal cell nevus syndrome - basal cell carcinomas, odontogenic keratocyst , PTCH gene, autosomal dominant).
  fibrothecoma Fibrothecoma has features of fibroma and thecoma.
  thecoma Thecoma has lipid vacuolated spindle cells with hyaline plaques. They can produce estrogens and androgens.
