Abstract
|
|
|
Penile melanosis is a benign macular hyperpigmentation of the penile shaft and/or glans. Clinically the lesions are irregular in outline and show variegated pigmentation. The main differential diagnostic problem is with acral lentiginous
melanoma.
A
28-year-old male was seen with slowly growing, asymptomatic, multifocal, and variegated hyperpigmented macules on the glans penis of a 2-year-duration. The past and family history were non-contributory. Histologic examination showed acanthosis
and
basal
layer hyperpigmentation but atypical melanocytes were not seen. Fontana-Masson stain showed increased melanin pigmentation with dendritic elongation of melanocytes in the basal layer of the epidermis. Little is known about the natural history and
melanoma risk of penile melanosis and we believe that a long-term follow-up is warranted. This patients showed no change during the follow-up period of 2 years and we will continue to monitor him long-term.
