Littoral cell angioma of the spleen: Cytological findings and review of the literature

We report the case of an 11-year-old boy with anemia, epigastric abdominal pain, and splenomegaly. The splenic lesions showed anastomosing vascular channels with cyst-like spaces filled by many sloughed endothelial cells, which were positive for CD68 and CD31 and negative for CD34. Scraping cytology revealed isolated and clusters of three-dimensional bland looking, epithelioid foamy tumoral cells with low nuclear cytoplasmic ratio, which mostly contained intracytoplasmic hemosiderin pigment. Although the fine needle aspiration cytology of splenic lesions is uncommon and LCA is a rare splenic lesion, it must be noted in the differential diagnosis of any splenic vascular neoplasm.
