Epithelial splenic cysts in children: surgical treatment by cyst-wall "peeling".

Primary splenic cysts are a rare finding. Some are large and require surgical removal. The epidermoid type has an epidermal lining, and prevention of recurrence is dependent on complete resection of the cyst wall, preserving the splenic tissue. Several open, laparoscopic, or percutaneous procedures have been proposed with or without splenic resection, but few give completely satisfactory results. Five consecutive splenic epithelial cysts in pediatric patients were treated by parenchyma-sparing complete removal of the cyst wall, which was gently peeled off the splenic tissue without major bleeding in all but one case. Long-term follow-up showed freedom from recurrence.
