Epidermal inclusion cysts are common epithelial cysts of the skin. The latter classically originate from progressive cystic ectasia of the infundibular portion of hair follicle. Therefore, these cysts are usually found in hairy regions and rarely in glabrous skin such as the palms and soles. The etiology of glabrous epidermal inclusion cysts appear to be different from that of those located in hairy regions. It has been suggested that implantation of epithelial cells into subcutaneous tissue, such as during trauma, is most likely the pathophysiologic basis. Epidermal inclusion cysts on the palms and soles are often misdiagnosed, leading to improper treatment. Therefore, we report a rare case of an epidermal inclusion cyst of the heel after minimally invasive surgery of a displaced intra-articular calcaneal fracture.
