Unilateral Tuberculosis Verrucosa Cutis: A Case Report

A 70-year-old Yemeni man presented with an 18-month history of asymptomatic hyperkeratotic nodules on his right foot. Physical examination revealed hard, brown nodules and plaques on the dorsum of the right foot. The left foot and rest of his integument were nodule-free. Punch biopsy revealed subcutaneous granulomas with multinucleated giant cells, findings consistent with cutaneous tuberculosis. A tuberculin test was strongly positive, whereas polymerase chain reaction testing of tissue specimens for Mycobacterium tuberculosis was negative. Based on the clinical and histopathological findings, the patient was diagnosed with tuberculosis verrucosa cutis. Antitubercular therapy was administered for 6 months, resulting in complete resolution of the lesions.
