An Unusual Case of Splenic Cyst: Epidermoid Cyst Masquerading as Hydatid Cyst

Abstract

Epidermoid cysts of the spleen are very rare benign tumors; characterized by a mesothelial invagination made of a stratified squamous epithelial lining of the splenic capsule during embryogenesis, they are primary non-traumatic and non-parasitic cysts, and they are generally of difficult diagnosis but the advent of CT and histology which remains the arsenal of diagnosis of epidermoid cysts of the spleen. We report a case of a young woman aged 25 years, without any notable pathological history presented with intermittent abdominal pain, with a large palpable splenic mass, ultrasound and abdominal CT scan objectified components that did not present the typical appearance of an epidermoid cyst and biology was in favor of a hydatid cyst igg positive. The patient underwent a total open splenectomy, the histopathological examination revealed the presence of a yellowish white material occupying the entire splenic parenchyma with the presence of numerous intracystic membranes, in addition there are surgical procedures opting for conservative treatment in our case we preferred totalization.
