Abstract

Papulonecrotic tuberculid is a rare, chronic, recurrent and symmetric eruption of necrotizing skin papules arising in crops, involving primarily the limbs. It occurs in less than 5% of active tuberculosis. Typically bacilli are not detected in any of the cutaneous lesions. Extracutaneous tuberculosis primary focus is only detected in 30-40% of the cases, being the lymph nodes the most common location. Anti-tuberculosis treatment is rapidly effective and is often the main confirmation of the diagnosis.

Keywords
