AI Article Synopsis
- Becker's naevus, also known as Becker's melanosis, is a type of skin growth characterized by brown pigmentation and excessive hair growth, primarily affecting young males after puberty.
- It has a prevalence of about 0.5% and typically appears as a noticeable, irregularly shaped dark spot on the upper body.
- Some cases can present with unusual features, leading to a condition called Becker's naevus syndrome, as evidenced by atypical presentations in two patients on their forearm and leg.
Article Abstract
Becker's naevus also known as Becker's melanosis (BM) or pigmented hairy epidermal naevus is a cutaneous hamartoma with brown hyperpigmentation and hypertrichosis. It commonly occurs during adolescence and rarely at birth. It usually affects young post-pubertal males and has a prevalence of 0.5%. A naevus usually consists of a circumscribed, unilateral, irregularly shaped, hyperpigmented spot usually located around the anterior upper body, with or without hypertrichosis and/or acneiform lesions. Sometimes developmental abnormalities can occur with Becker's naevus, which is called Becker's naevus syndrome (BNS). Becker's naevus was of atypical presentation in two patients over the forearm and leg. Hence, these case reports gain importance.

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.

This case report explores a rare manifestation of Becker's nevus, where the patient exhibited an unusual dermatomal distribution featuring a hyperpigmented, irregular patch with associated hypertrichosis on the T4 segment. While Becker's nevus is a well-known dermatological condition typically observed in the upper back region, instances of dermatomal distribution are exceptionally uncommon. This case presents a unique occurrence of segmental Becker's nevus, highlighting the atypical presentation of this condition.
