Papulonecrotic tuberculid (PNT) is a host immune and allergic reaction to Mycobacterium tuberculosis infection in other parts of the body. Early-stage PNT is highly likely to be misdiagnosed as allergic vasculitis, which can be identified by pathological biopsy or PCR. In this article, we reported 1 case of lymph node tuberculosis, drug-induced liver injury complicated PNT, presenting with bipedal rash as the first manifestation. Desensitization and symptomatic treatment yielded low efficacy. The medical history of the patient was inquired and clinical diagnosis was confirmed after pathological biopsy. Anti-tuberculosis drug regimen and symptomatic treatment were adjusted. No new rash was observed during the outpatient follow-up. This case prompts that for patients suspected with Mycobacterium tuberculosis infection complicated with skin rash, the possibility of complicated with various types of skin tuberculosis and the differential diagnosis should be considered. The drug regime should be properly adjusted for patients who cannot tolerate conventional treatment.
