Penile epidermoid cyst following traditional circumcision: a case report

Epidermoid cysts (EC) are among the most common benign swellings that can develop in any part of the body. EC occurring on the penis is usually rare and congenital. Here, we report a case of an EC of the penis that developed in a 37-year-old man following a Maasai circumcision.

A 37-year-old male, who presented with a swelling on the distal penile (preputial) following a Maasai circumcision done in 1999, had the swelling for 15 years. A total cyst excision was done, and the sample was taken for histopathological investigation. Gross features of the sample: single nodular specimen encapsulated, size 4 × 2 cm, soft, showing brownish gelatinous materials in a cystic capsule. Microscopy: The section showed cystic lesions lined by keratinized stratified squamous epithelium with abundant keratin nodules in a cystic cavity. A histological diagnosis of an EC was reached.

ECs are among the most common benign swellings that can develop anywhere or any part of the body. EC in adults might develop after previous trauma or surgery when epidermal components are trapped inside a closed space. Thorough physical examination and investigations, including ultrasonography and computed tomography, may help diagnose an EC. The definitive and recommended choice of treatment for an EC of the penis is surgical excision.

In situations of cystic, asymptomatic, non-tender lesions situated on the penis, EC should be suspected. Total excision is the recommended treatment of choice.
