Penile epidermal inclusion cyst

Abstract

We report a case of epidermal inclusion cyst of penis in a five-year-old boy, who had presented to the outpatient department of our hospital. Epidermal inclusion cysts are benign lesions that can develop in any part of the body. However, the finding of an epidermal inclusion cyst in the penis is rare. The child was operated and discharged uneventfully. The objective of reporting this case is to highlight the rare possibility of an inclusion cyst arising from penis as a late complication of circumcision.

Penile epidermal inclusion cyst: a rare location

“…The condition is rare in the penis and can occur after an apparently minor procedure such as circumcision 1. In our case, an ultrasound scan showed homogenous internal echoes with absence of vascularity.…”

Penile Epidermal Cyst in a Patient With Augmentation Penoplasty

“…Congenital cysts, such as median raphe cysts, can arise from an abnormal embryological closure of the median raphe [2-4]. Secondary cysts can occur because of occluded hair follicles, mechanical implantation involving the injection of epidermal fragments, and obstructed eccrine ducts [5-7].…”

“…Penile epidermal cysts in children are usually congenital and are caused by abnormal embryologic closure of the median raphe; these cysts are termed median raphe cysts [2-4]. Penile epidermal cysts in adults commonly develop after trauma or surgery.…”

Penile Epidermal Inclusion Cyst

“…Epidermal inclusion cyst results from implantation and proliferation of epidermal element in the dermis [2]. Epidermal inclusion cyst can arise from surgical implantation of epidermal tissue, as in this patient, these cysts may also arise from the sequestration of epidermal rests during embryonic life, occlusion of the pilosebaceous unit, or traumatic implantation of epithelial elements [3].…”
