We report a case of postherpetic. granulomatous folliculitis in a 52-year-o
ld female. The several cutaneous granulomatous eruptions following herpes z
oster reported in the literature include annular, sarcoid and tuberculoid g
ranuloma, granulomatous vasculitis and granulomatous folliculitis. The mech
anism of granuloma formation is probably triggered by a delayed hypersensit
ivity response to the virus.
