[Papulonecrotic tuberculid].
Papulonecrotic tuberculid (PTB) is a form of cutaneous tuberculosis with characteristic clinical and histological manifestations. The incidence of PNT is very low in Spain. We present the case of a 22-year-old male patient from a middle-class social and economic background, with clinical and histological criteria of PNT, but who showed negative for molecular traces of mycobacteria using PCR.
