Penile Epidermal Cyst: A Case Report.

Area of Science:

• Dermatology
• Urology
• Pathology

Background:

• Epidermal cysts (epidermoid cysts) are common benign tumors.
• Penile epidermal cysts are exceptionally rare, with congenital cases in children termed median raphe cysts (MRCs).
• Adult cases can arise from trapped epidermal elements post-trauma or surgery.

Observation:

• This report details a rare case of a penile epidermoid cyst.
• The patient presented with significant discomfort during coitus as the primary complaint.
• The cyst resulted from keratinization of trapped squamous epithelium during wound healing.

Findings:

• Confirmation of a penile epidermoid cyst.
• Demonstration of cyst formation via trapped epidermal elements and keratinization.
• Association of penile epidermoid cyst with sexual discomfort.

Implications:

• Highlights the rarity of penile epidermoid cysts in adults.
• Underscores the importance of considering epidermal cysts in penile lesions, even when rare.
• Suggests potential impact on quality of life, including sexual function.
