Tufted Hair Folliculitis in a Patient Affected by Pachydermoperiostosis: Case Report and Videodermoscopic Features

A 25-year-old man with Touraine-Solente-Golé syndrome, also known as primary pachydermoperiostosis, presented with tufted hair folliculitis, a variant of folliculitis decalvans, characterized by an inflammatory scalp condition with tufts of 10 to 20 hairs emerging from single follicular openings. The condition was associated with Staphylococcus aureus infection. Videodermoscopy revealed specific patterns indicative of the condition, and histological examination confirmed the diagnosis. The patient was treated with amoxicillin and clavulanic acid, along with topical nadifloxacin, resulting in significant clinical improvement. After treatment, only a single area of cicatricial alopecia remained, with no new lesions or symptoms.
