Two patients suffered from ′boils′ on their arms and/or thighs for several months. A diagnosis of papulonecrotic tuberculid (PNT) was made based on clinical, laboratory parameters, histopathology, and a prompt response to multi-drug anti-tuberculosis treatment. We checked the pathological sections carefully and finally found a small amount of positive acid-fast bacilli. We analyzed the clinical and histopathological features of PNT in order to offer reference of preventing and controlling the disease.
