Umbilical epidermal inclusion cysts, an unusual cause of umbilical mass following laparoscopic surgery: case report

Abstract

Abstract Umbilical lumps are a common presentation that can represent a diagnostic challenge as the differentials are broad. Epidermal inclusion cysts occur when epidermal cells are implanted in the dermis following trauma, or surgery. Although epidermal inclusion cysts are common, they are rarely cause of umbilical mass, with less than 10 cases described in the literature. Very few cases have been reported following abdominal surgery and none following laparoscopy. These lesions can occur with or without pain, mass, redness or spontaneous discharge and symptoms can persist for years. This paper reports a case of an umbilical epidermal inclusion cyst in a 52-year-old female presenting with a 6-week history of a painful, red umbilical lump on a background of two previous diagnostic laparoscopies. This was successfully treated with complete excision of the lesion.
