What’s new in gynecologic pathology 2021: ovary and fallopian tube

The 5th edition of the World Health Organization (WHO) Classification of Female Genital Tumors was published in 2020. Although the classification of ovarian and fallopian tube neoplasms is largely unchanged from the prior (4th) edition, this newsletter compiles the most important refinements in these organ sites, including serous and non-serous epithelial tumors, and sex cord-stromal tumors.

Wollfian tumor: a case report and a literature review

Wolffian tumor is a rare neoplasm arising from mesonephric duct remnants. Not more than 100 cases of the disease have been described. The authors present their own clinical observation of the Wolffian tumor in a 43-year old female patient. Radiological examinations resulted in the suspicion of a subserous leiomyoma of the uterus; however, the surgery showed a mass arising from the fallopian tube wall. Histologically, there was a growing tumor within the fallopian tube wall with no mucosal lesions. The tumor consisted of myxomatous stroma with cribriform, solid and reticular areas composed of relatively monomorphic, mildly eosinophilic cells with monotonous nuclei and single mitoses. On immunohistochemistry, the tumor cells expressed vimentin, pan-cytokeratin, cytokeratin 7 and calretinin. This case illustrates that final verification and differential diagnosis of the tumor with other fallopian tube neoplasms, including malignancies, is only possible with an immunohistochemical study.

Fallopian Tube Papilloma – Case Report of a Rare Tumor

Fallopian tube neoplasms are rare. We report a rare case of fallopian tube papilloma discovered incidentally in a 45 year old female, operated for procidentia. Right tube was dilated at the infundibular region, with friable grey white tissue in the lumen. Microscopy showed delicate branching papillae lined by a single layer of epithelium resembling tubal lining. There were no features to suggest a reactive hyperplasia in response to inflammation or of aggressive behaviour.
