title: Tinea capitis mimicking tufted hair folliculitis.
abstract: We report a case of tinea capitis mimicking tufted hair folliculitis in a 56-year-old European man, who presented with a 4-year history of pain and erythema in an area of scarring alopecia of the occipital scalp, with scales and tufts of hair emerging from individual follicles. Histological examination showed hair plugging, and a dense perifollicular infiltrate of plasma cells, lymphocytes, and neutrophils. There was widespread scarring and fibrosis. Bacterial cultures were negative for Staphylococcus aureus, but fungal cultures and periodic-acid-Schiff stain were positive for Trichophyton tonsurans. Videodermatoscopy of the lesion showed a pattern consistent with folliculitis decalvans. Diagnosis was made on the basis of the clinical, histological, microbiological and videodermatoscopy data. After 30 days of systemic antifungal treatment, there were a substantial clinical improvement and disappearance of pain. After 5 months, a residual cicatricial area was seen with some hair tufts emerging from a single orifice.
