Squamous cell carcinoma is related to exposure to UVB radiation and the presence of chronic cutaneous lesions. Folliculitis decalvans is a cicatricial alopecia that develops with the inflammation of the scalp. In the medical literature, the association between folliculitis decalvans and squamous cell carcinoma is rare, a factor motivating this report.
