A case of giant epidermoid cyst on the penis

Acquired Penile Epidermoid Cysts in Children

Background

In this study, we aim to present the experience of a tertiary center regarding penile epidermoid cysts over 15 years.

Methodology

Patient files of those who underwent surgical excision for penile epidermoid cysts between 2005 and 2019 were reviewed retrospectively. The demographics, clinical characteristics, etiological factors, cyst features, surgical techniques, complications, and follow-up data were analyzed.

Results

In total, 24 penile epidermoid cysts were excised in 21 boys. The median age at the time of surgery was 52 (15-204) months. The median duration between previous surgery and cyst excision was 40 (1-180) months. In total, 11 cases had a history of circumcision, and 10 had undergone hypospadias surgery. There was no significant difference between these two etiologic groups (p > 0.05). The main symptom was an asymptomatic penile mass. The average cyst size was 9.4 ± 6.7 mm. All cysts were completely excised with incisions made over old scars, except one. No complications were observed during a median follow-up period of 50 (12-120) months, and only one recurrence was noted.

Conclusions

Acquired penile epidermoid cysts may present as an early or late complication after penile surgery. Complete excision with an incision along the existing scars seems to be an effective solution for preventing new scars.

MRI of the Penis: Indications, Anatomy, and Pathology

The purpose of this review is to discuss the role of magnetic resonance imaging (MRI) in the evaluation of penile pathology. Normal penile anatomy as well as the appearance of neoplastic and non-neoplastic entities on MRI will be reviewed. While ultrasound remains the first line imaging modality in evaluating most penile pathology, MR imaging has specific advantages owing to improved soft tissue resolution, ability to evaluate less accessible or complex anatomy (such as at the base of the penis), and the ability to detect subtle enhancement. Therefore, MRI is useful for when ultrasound and/or clinical findings are equivocal or incongruent. In addition, MR imaging is essential for preoperative surgical planning and is the imaging modality of choice in evaluating penile prostheses. The added value of MRI in these settings makes it an integral component to the management of many pathological entities affecting the penis.

An epidermal cyst of the penis after distal hypospadias surgery: a case report

Background

Epidermoid cyst is a benign tumor that can occur anywhere in the body but is rarely seen in the penis. Congenital and previous penile surgeries have been reported to be involved in the etiology of the disease, which is usually asymptomatic. Here we describe a case of a patient with a penile epidermoid cyst, which occurred in the circumcision line on the left side of his penis, and urethral dehiscence following hypospadias surgery.

Case summary

A 3-year-old white boy who underwent primary distal hypospadias surgery 1.5 years ago presented with a slowly growing mass in the left ventrolateral portion of the penile circumcision line and urethral dehiscence. The histology of the excised mass revealed an epidermal inclusion cyst. Since then, he has remained healthy.

Conclusions

Epidermal inclusion cyst as a complication of hypospadias surgery is a very rare situation. The diagnosis is made histologically and surgical excision is sufficient for treatment.
