Penile Epidermal Inclusion Cyst: A Late Complication of Penile Girth Enhancement Surgery

Abstract

Introduction 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. Aim The aim of this article was to present the management of a case of a penile epidermal inclusion cyst that occurred because of late complications of a penile girth enhancement surgery. Methods A 52-year-old man presented with a painless, slowly growing mass in the penis, which was first noted after a penile girth enhancement surgery 20 years ago. A cystic mobile mass about 2 cm in depth was found surrounding the coronal sulcus. Excision of the mass was performed for diagnosis and treatment. Results There was no communication with the urethra. The pathological diagnosis was an epidermal inclusion cyst of the penis. Conclusions A penile epidermal inclusion cyst in adult men is rare. It can develop after an inadequate procedure for penile girth enhancement, and should be treated by complete resection.

Penile epidermal inclusion cyst

“…A case report of epidermal inclusion cyst of penis occurring after penile girth enhancement surgery could also be found. 6 In our patient there was a history of undergoing religious circumcision in early infancy that could well be the cause of the inclusion cyst. The swelling appears to have its origin from the shaft of the penis near the corona (Fig.…”

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]. Because the patient in this case had undergone an augmentation penoplasty with a dermal fat graft, we suspect that the cyst originated from the dermal fat graft.…”

“…Penile epidermal cysts can be diagnosed by careful examination and radiological evaluation, including ultrasonography and computed tomography [5-7]. Magnetic resonance imaging may be useful in cases of suspected extension into the pelvis, although such cases are rare [6].…”

“…Magnetic resonance imaging may be useful in cases of suspected extension into the pelvis, although such cases are rare [6]. If a urethral diverticula or urethrocutaneous fistula is suspected, retrograde urethrography or voiding cystourethrography should be carried out [5-7]. In addition, the differential diagnosis of an epidermal cyst includes teratoma and dermoid cyst.…”

“…Penile epidermal cysts in adults commonly develop after trauma or surgery. During wound healing, when shedding of the epithelium occurs within a closed space, cysts are formed by squamous epithelium undergoing keratinization [5-7]. According to this theory, an augmentation penoplasty using a dermal fat graft can cause a penile epidermal cyst.…”
