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.

Inflammatory pseudotumor (IPT) of the spleen is an uncommon entity with debated etiology, characterized by a mixture of inflammatory cells and a component of myofibroblastic spindle cells. This lesion needs to be distinguished from the follicular dendritic cell tumor and the inflammatory myofibroblastic tumor. We report two cases of splenic PTI in a 69-year old and a 62-year old women. The tumors measured respectively 80 and 30 mn in greatest dimension. An inflammatory pseudotumor was histopathologically diagnosed following a splenectomy.
