Abstract
A 62-year-old woman, who had been diagnosed as tuberculosis in the cervical lymph nodes and lung and treated with anti-tuberculosis chemotherapy, developed recurrent subcutaneous nodules in her trunk. These lesions presented at intervals of a few months as skin-colored or brown painless swelling that demonstrated watery or purulent material when incised. Some ulcerative lesions spontaneously healed. Histopathology of the lesion revealed epitheloid cell granuloma associated with caseation necrosis, suggesting tuberculosis infection. Despite no colonies growing in culture, PCR successfully detected the genome specific for Mycobacterium tuberculosis. Collectively, we made a diagnosis of recurrent scrofuloderma.
