Pityrosporum folliculitis is an acute pruritic eruption caused by Malassezia furfur, the causative organism of tinea versicolor. The condition is seen more frequently in teenagers than in children.
Immunocompromised patients, including patients on chronic oral prednisone, diabetic patients, and those on chronic systemic antibiotics, are particularly predisposed to this condition.
