CASE SERIES – GIANT EPIDERMAL INCLUSION CYST OF GLUTEAL REGION AND CHEST

Abstract

Epidermal cyst is the most common type of cyst to occur in subcutaneous tissue. It is usually small, asymptomatic, and solitary in lesion. When the size is greater than 5 cm, it is classified as a giant epidermal cyst. If the size is big, it may sometimes mimic a soft tissue sarcoma, hence requiring further evaluation with imaging or histopathological studies. We report a case series of two patients whom presented with a huge swelling at different body regions, involving gluteal and chest. Both patients underwent different modes of imaging to delineate the anatomical extent of the lesion. Excision biopsy was done and the histopathological report confirmed epidermal cyst with no malignancy. The purpose of this case series is to describe the rare occurrence of giant epidermal cyst and to elaborate the methods of approach to arrive at the diagnosis.
