Splenic epidermoid cyst.

Splenic epidermoid cyst is a rare cystic disease affecting the spleen. We report a young male who presented with a painless abdominal lump. Ultrasonography and CT scan of abdomen showed a huge cystic lesion of obscure origin. At laparotomy a huge cyst was found to be arising from the superior pole of the spleen, and its removal necessitated splenectomy. Histopathological findings were consistent with splenic epidermoid cyst. The aetiopathology and different treatment modalities of splenic cysts are discussed.
