Abstract
Becker's melanosis, also known as Becker nevus, is a relatively common, usually affects young males, singular, cutaneous hamartoma, which is classically characterized by a unilateral hyperpigmented, hypertrichotic patch on the upper trunk or proximal upper extremities, with its onset during the peripubertal years. A 19- year-old female patient had multiple becker nevi at right arm, right mid back and left knee area. Histopathology from all the lesion are compatible with Becker’s nevus.
Highlights
We report here a rare case of systematized Becker’s naevi with 3 distinct lesions present on different sites with atypical morphology
A 19-year-old female patient presented to us for asymptomatic three brown colored lesions over the body that she noticed since five years
Our case is presented to emphasize the fact that in a female patient, Becker’s melanosis should be rule out even if multiple lesions are present at atypical sites even without hypertrichosis
Summary
Becker’s naevus (pigmented hairy epidermal naevus), a variety of epidermal naevus, is present in about 0.5% of young men. It is a unilateral single lesion present on shoulder upper arm, anterior chest or scapular region in males, appearing during adolescence. Becker nevus is uncommon in females, atypical lesions and multiple sites are more uncommon.
