Epidermoid Cysts in a Wandering Spleen: An Unusual Enigma.

Epidermoid splenic cysts are rare lesions in the spleen. These cysts are characterized by a stratified squamous epithelial lining, internal septations, and calcification. Congenital in origin, epidermoid splenic cysts are postulated to arise from misfolding and mesothelial cell incorporation into the splenic parenchyma. This report presents a unique case of an 18-year-old woman with an epidermoid splenic cyst in a congenital wandering spleen. Computed tomography and transabdominal ultrasound imaging along with immunochemistry staining confirmed the diagnosis. To the authors' knowledge, this is the first reported case of an epidermoid cyst in a wandering spleen.
