A case of persistent beard folliculitis.

A 48-year-old agronomist with no history of comorbidities or medication intake consulted with a two-month history of progressive swelling on his upper lip. He did not complain of any symptoms, and the lesion was refractory to oral antibiotic and antiviral treatments. He denied any recent contact with animals. On physical examination, he had a boggy erythematous plaque consisting of pustules and crusts on the upper left lip (Figure 1a). Hair was easily pluckable, causing less density. Tinea barbae was suspected; Crusts and pustules were taken for microbiological tests.
