A 5-year-old girl had a unilateral rash on her right cheek. Histologic investigations showed aberrant pilosebaceous units and elastotic material in the papillary dermis. Unilateral folliculitis ulerythematosa reticulata (a variant of keratosis pilaris atrophicans) is strikingly rare, and its very early clinical and microscopic changes are demonstrated in this case report.
