Traumatic anserine folliculosis (TAF) is an infrequently reported condition, presenting with grouped follicular papules, usually on the face of young people, induced by repeated frictional trauma or pressure. A suggestive history may allow clinical differentiation of TAF from other folliculocentric keratotic disorders. We present three children diagnosed with TAF in our department: (i) A 12-year-old boy with asymmetry of the mental protuberance, presented with a 1-year history of scaly, lichenified erythema with monomorphic nonpigmented papules over the more prominent side; histology showed mild hyperkeratosis and some rudimentary hair follicles with keratin-filled follicular openings. (ii) A 7-year-old boy with a 1-year history of a hyperpigmented patch on the chin with multiple skin-coloured papules and a sandpaper feel; dermoscopy showed follicular papules with keratin plug; he had a habit of reading with his chin resting on his knee; the skin changes improved with topical retinoid and postural changes. (iii) A boy with follicular papules on one cheek since the age of 8 years, with history of persistent leaning his hand on his cheek while reading; the papules resolved with a change in posture, but similar changes arose at a new pressure area on his chin. The clinical features of grouped monomorphic skin-coloured follicular papules on an erythematous or hyperpigmented background, and a suggestive history, may allow the diagnosis of TAF. Described histological findings are hyperkeratosis, rudimentary follicles and dilated follicular openings filled with keratotic material. Management includes identifying and correcting postural habits; topical keratolytic agents and retinoids may also be beneficial. [ABSTRACT FROM AUTHOR] |
