Sebaceous Gland Hyperplasia of the Penis
These papular lesions on the penis of a 14-year-old boy first appeared 1 year before presentation. The lesions had remained unchanged in size and number and were asymptomatic. Urination and penile erection were undisturbed.
On examination, multiple yellowish papules were noted on the dorsal surface of the distal penile shaft. A clinical diagnosis of sebaceous gland hyperplasia of the penis was made.
Also known as sebaceous gland prominence on the penis and ectopic sebaceous glands (Fordyce disease), sebaceous gland hyperplasia of the penis typically presents as soft, yellowish papules, 1 to 3 mm in diameter, on the penile shaft. The condition is asymptomatic.
Histologically, the sebaceous glands in the upper dermis in the penile shaft are hyperplastic, with lobules of varying sizes. The clinical differential diagnosis includes sebaceous adenoma, milia, lichen planus, lichen nitidus, pearly penile papules, and warts.
The patient was reassured of the benign nature of the condition and that no treatment was required. The lesions were still present after 2 years.
