Follicular Becker's Nevus: A Rare Variant - Becker's nevus is a cutaneous hamartoma, characterized by the presence of hyperpigmentation, hypertrichosis, and smooth muscle proliferation. Recently a report describing a rare follicular variant of Becker's nevus was published in the Indian Dermatology Online Journal.
An 18‑year‑old man presented with multiple asymptomatic well‑defined, folliculocentric macules tending to coalesce at one side over the right chest and supraclavicular area since 1.5 years which was gradually progressive in nature. There was no history of seizures, developmental delay or any other neurological complaints associated with the lesion. The patch had terminal hair in at the centre of each hyperpigmented macule without any skin thickening or nodularity. There was no evidence of limb or breast hypoplasia or asymmetry.
Dermoscopy (Dermlite DL200 Hybrid M; polarized mode) showed a well‑defined network‑like pigmentation with immediate perifollicular hypopigmentation and well‑defined areas of darker pigment network surrounding these areas. Histopathology demonstrated hyperpigmentation of the basal layer and regular acanthosis with no evidence of dermal smooth muscle proliferation. Thus, a final diagnosis of follicular Becker's nevus was made. The patient was counselled about the nature of the condition and advised treatment with Q‑switched ND-YAG laser in higher centres.
