ABSTRACT
Through this case presentation and a review of the literature, we aim to describe clinical and pathologic features and to distinguish the outcome of these tumors. A 25-year-old woman presented with pelvic pain and an iliac mass. Workup revealed a 53-mm cystic partitioned mass of the left ovary infiltrating the left sacrum. She underwent a left adnexectomy. Gross examination revealed a ruptured ovarian mass. When dissected, it showed grayish cerebroid aspects. Histologic examination revealed a malignant tumor proliferation of the diffuse large cells. An immunohistochemical analysis showed negative results for PLAP, αFP, ßHCG, CD117, CK20, and CD30. It also showed lack of B markers and T marker (CD3) and an expression of CD138 and anaplastic lymphoma kinase. The patient was treated by 6 cycles of CHOP chemotherapy and a pelvic radiotherapy. She presented with a 15-cm splenomegaly 26 months later and died of febrile neutropenia. Most patients follow an aggressive disease and are unlikely to respond to the standard.
