Recalcitrant Dissecting Cellulitis of the Scalp Treated Successfully with Adalimumab with Hair Regrowth: A Case Report.

Dissecting cellulitis (DC) of the scalp or perifolliculitis capitis abscedens et suffodiens is a rare chronic inflammatory condition of the scalp manifested by perifollicular pustules, nodules, abscesses and sinuses that result into scarring alopecia. Treatment of DC is challenging and often disappointing. We report a 38-year-old male patient with DC for 5 years, and multiple topical and systemic therapies had shown poor effect. This patient achieved excellent response to adalimumab with hair regrowth.
