Specialty	Dermatology

Sycosis vulgaris is a cutaneous condition characterized by a chronic infection of the chin or bearded region.^[1]^: 252^[2]

The irritation is caused by a deep infection of hair follicles, often by species ofStaphylococcus orPropionibacteriumbacteria.^[3] It usually affects men who shave as this results in bacterial inoculation all over the face. Asymptomatic or painful and tendererythematous papules and pustules may form around coarse hair in the beard (sycosis barbae) or the back of the neck (sycosis nuchae).^{[citation needed]} In more severe cases, there may be crusting, follicular destruction and scarring.^[4]
