Nodular tuberculid in a patient with HIV.
Tuberculids (papulonecrotic tuberculid, erythema induratum, and lichen scrofulosorum) are cutaneous hypersensitivity reactions to Mycobacterium tuberculosis . We report the fifth case of a recently described tuberculid, nodular tuberculid. The distinguishing feature was that of a granulomatous vasculitis occurring at the dermohypodermal junction on biopsy specimen of the subcutaneous nodules.
