Tuberculosis verrucosa cutis masqerading as chromoblastomycosis – a case report

Abstract

Tuberculosis verrucosa cutis (TVC) also known as prosector’s wart occurs due to exogenous inoculation of tubercle bacilli into the skin. A 52 year old female came with complaints of raised skin lesion over the left leg and foot since 20 years. Pain and discharge from the lesion was present since 15 days. History of swelling of the left leg since 2 weeks. Cutaneous examination revealed multiple well defined erythematous to flesh coloured soft nodules over left lower leg with surrounding hyperpigmented scaly plaque. A well defined hyperpigmented verrucous plaque with central depigmentation over left foot. Lupus vulgaris and chromoblastomycosis were the provisional diagnosis. Mantoux test was positive. Biopsy was suggestive of TBVC. Patient was treated with anti-tuberculous therapy. TBVC usually presents as a single verrucous lesion over exposed areas of the body. Our patient here presented with multiple nodules and hyperpigmented plaque over the left lower limb which was mimicking chromoblastomycosis.
