Penile melanosis with annular fibrillar pattern

Abstract

Penile melanosis is an uncommon but benign condition. Its appearance, however, can cause significant distress to patients. We report a case of a patient presenting with hyperpigmented annular penile macules, with a fibrillar pattern seen on dermoscopy. Histopathological examination revealed basal keratinocyte hyperpigmentation with no melanocytic proliferation or atypia, confirming our diagnosis of penile melanosis. The patient was managed conservatively. We also reviewed the literature surrounding the clinical assessment and management of penile melanosis. Future reports on this topic with clinical‐dermoscopic‐pathological correlations will aid further understanding of this seldom reported condition.
