Papulonecrotic tuberculid in a 9-year-old American girl: case report and review of the literature.

Papulonecrotic tuberculid is a rare cutaneous manifestation of tuberculosis that can also be associated with other mycobacteria. Clinically, it is an asymptomatic, recurrent eruption of papules with a necrotic center in a symmetric, acral distribution. Tubercle bacilli are not present in skin biopsies. The eruption resolves promptly with antituberculoid therapy. Few patients with this entity have been reported in the United States over the last 50 years. We report a 9-year-old, otherwise healthy, American girl whose sole initial findings were lesions of papulonecrotic tuberculid secondary to Mycobacterium tuberculosis.
