Abstract
Well-differentiated mesothelial tumors are uncommon lesions of low malignant potential but are associated with high rates of recurrence. Tumors of <2 cm are considered benign and show low-grade histology, while tumors larger than this are associated with high-grade histology and greater chances of dissemination. To date, only three cases of papillary mesothelioma, all unilateral and <6 cm in size, have been reported arising from the ovary. We performed a panhysterectomy for a clinico-imaging diagnosis of bilateral ovarian carcinoma. Preoperative examination revealed large papillary tumors arising from the surface of both ovaries, which on histopathology turned out to be well-differentiated mesothelial tumors. To the best of our knowledge, a bilateral, 15-cm, low-grade papillary mesothelioma has not been reported in the literature so far. (J GYNECOL SURG 29:59)
