AI Article Synopsis
- Becker's nevus is a specific type of hyperpigmented skin lesion that can be present at birth or develop later, characterized by dark pigmentation and increased hair growth.
- A case study of a 21-year-old male revealed a hyperpigmented lesion on his arm that started at age 16, showing growth and irregular edges, leading to a diagnosis of Becker's nevus based on clinical assessment. *
Article Abstract
Nevus is a group of melanocytes that grow together to form a benign growth on the skin. It is often a black lesion that may protrude from the skin. Becker's nevus is a hyperpigmented lesion that presents congenitally or is acquired. The pigmentation and unusually high hair growth might grow darker with time. Becker's nevus, which can interchangeably be called Becker's melanosis, is a rare disease usually presented by men. The following case is of a 21-year-old male who presented with a hyperpigmented lesion on his right arm. The lesion started at age 16 and increased in size gradually; it involved the flexor surface of the right elbow joint and showed hypertrichosis with irregular margins. On examination, the top dermis contained melanophages, and the basal layer was hyperpigmented. Based on clinical appearance and examination, Becker's nevus was diagnosed.

Article Synopsis
- Becker's nevus (BN) is a benign, unilateral skin lesion that shows up as a hyperpigmented, hairy area, usually seen in adolescents, and is rarely found on the lower limbs.
- A 17-year-old boy presented with typical dermoscopic signs of BN on his lower leg, highlighting the effectiveness of dermoscopy in the diagnosis.
- While no definitive treatment exists for BN, cosmetic improvements are often the goal, and laser therapy has been found effective; however, treatment may not be necessary if the patient is unconcerned about appearance.
