Littoral cell angioma in a patient with Epstein syndrome

A 61-year-old male with Epstein syndrome and chronic renal failure was admitted to our institution for kidney transplantation. He was asymptomatic at the time of evaluation. Physical examination revealed pallor and marked splenomegaly measuring approximately 12 x 10 cm below the left costal margin. Because of this finding, and a history of resected non-small lung cancer, a CT scan of the abdomen was obtained. This demonstrated massive, diffusely nodular splenomegaly. This article describes the histopathologic and immunohistochemical findings of littoral cell angioma, a novel splenic tumor. Also, we discuss the differential diagnosis and include a description of the imaging study performed. To our knowledge, this is the first case report of littoral cell angioma occurring in a patient with Epstein syndrome, and the first radiographic appearance of this rare tumor.
