Clinical and Trichoscopy Features in Trichorhinophalangeal Syndrome: A Multicenter Retrospective Study.

Introduction: Trichorhinophalangeal syndrome (TRPS) is a rare autosomal dominant genetic disorder characterized by trichological, craniofacial, and skeletal abnormalities. To date, limited data are available on hair involvement in TRPS, especially those focusing on trichoscopy.

Objective: We aimed to describe the epidemiology and the clinical and trichoscopy features of TRPS.

Hydroxychloroquine may be beneficial as an adjuvant therapy for folliculitis decalvans: a 5-year retrospective study with 49 patients.

Folliculitis decalvans (FD) is a chronic and recurrent neutrophilic scarring alopecia that mostly affects the vertex scalp of young male patients. It manifests as painful alopecic lesions surrounded by pustules, tuftings and intense scalp fibrosis. However, the occurrence of less active or 'lichen planopilaris-like' forms of FD questions the exact role of Staphylococcus aureus in the pathogenic mechanism of this disease.
