A Case of Tuberculosis Verrucosa Cutis / 대한피부과학회지

ABSTRACT

We report a case of tuberculosis verrucosa cutis in a 64-year-old male patient, who had multiple verrucous plaques on his right hand for twenty years. His past history revealed a previous history of injury on his lesion site. Histologic features consisted of hyperkeratosis, acanthosis in the epidermis with inflammatory infiltrate and tuberculoid granuloma in the dermis. It was suspected that the patient had tuberculosis verrucosa cutis, but no bacilli was found in the lesion in the AFB stain. Then we performed PCR, which showed a positive result. We started antituberculosis medication, and the lesions cleared up after 6 months of treatment with isoniazid, rifampicin, pyrazinamide, and ethambutol. The lesions were later confirmed to be tuberculosis by the AFB culture. We suggest that early diagnosis of tuberculosis verrucosa cutis can be made by using PCR.
