Epidermoid cyst of the spleen - A case report

Abstract

Splenic cysts are rare entities. Epidermoid cysts of the spleen constitute 10% of total splenic cysts. These cysts are more common in children and young adults. We report a case of 21 year-old female who presented with left sided dull aching, intermittent abdominal pain and a palpable mass in the left hypochondrium. USG abdomen showed gross splenomegaly with a large cystic lesion in the spleen. CT scan revealed a grossly enlarged spleen with a cystic lesion suggestive of a splenic cyst and mild hepatomegaly. USG guided aspiration of the cyst and pigtail catheter insertion was done. Cystic fluid analysis was suggestive of epidermoid cyst of the spleen. Laparoscopic total splenectomy was done and histopathological evaluation revealed fibrosed cyst wall with stratified squamous lining confirming the diagnosis of epidermoid cyst of spleen. This case report favours total splenectomy based on the size of the cyst for a better post-operative outcome. A definitive diagnosis of epidermoid cyst of the spleen requires histopathological evaluation.
