Borderline Ovarian Serous Adenofibromatous tumor With Prominent Micro papillary Pattern. A case report

Ovarian borderline serous tumors are uncommon. Combination of borderline serousadenofibromatous tumor and prominent micro papillary architecture is not previouslyreported.We report a case of borderline papillary serous adenofibromatous tumor (also called serousadenocarcinofibroma) with extensive micro papillary pattern in a 27 year-old marriedwoman. She was infertile and presented with diffuse abdominal pain and dysparonia.Bilateral 5.3 and 4.5 cm solid ovarian masses were detected by sonography. Both masseswere ovoid with tan-pink bosselated smooth external surfaces, and solid tan lobular cutsurfaces. Microscopically, both tumors showed many papillary structures in a fibrotic stromaand contained multiple psammoma bodies. The papillae had broad hyalinized fibrotic stromawith many micro papillary projections arising from the main papilla, lined by mildlypleomorphic cuboidal cells. Mitotic activity was low with no marked nuclear atypia orstromal invasion. No extraovarian implants were identified.Keywords: Ovarian tumor, Borderline tumor, Serous papillary adenocarcinofiboma, Micropapillary pattern, Adenofibromatous tumor, noninvasive micropapillary serous carcinoma.
