A-10-year-old boy presented with hypopigmented soft plaque over the left lateral eyebrow and forehead for 5 months. There was complete loss of eyebrows in the involved area. Discrete brown follicular plugs were seen at the centre of the plaque [Figure - 1]. There was no history of atopy, sensory loss or systemic complaints. Biopsy from the centre of the plaque revealed follicular plugging, superficial and deep dense perifollicular infiltrate of lymphohistiocytes and mucin deposition within few hair follicles, favoring the diagnosis of follicular mucinosis. There were no atypical cells or epidermotropism. Staining for acid-fast bacilli was negative. He was started on medium-potency topical steroids. He remains under regular follow-up and after 3 months of initiating treatment there was partial improvement in pigmentation and no new lesions. The differentials that should be considered for follicular mucinosis are borderline tuberculoid hansens disease, especially in areas endemic for leprosy, lichen spinulosus, keratosis pilaris, lymphomas, lymphocytic infiltrates, etc., depending on the morphology of the lesion.
