Tuberculosis Verrucosa Cutis Presenting as Diffuse Plantar Keratoderma: An Unusual Sight

Tuberculosis verrucosa cutis (TVC) is a common cutaneous form of paucibacillary tuberculosis in an individual with moderate to high degree of immunity to Mycobacterium tuberculosis infection. Clinical appearance of TVC is mostly very typical with well-defined warty plaques presenting mostly on hands, knees, ankle, and buttocks; however several atypical morphology of the lesions have also been described. We hereby report a case of TVC, masquerading as asymptomatic diffuse keratoderma of left foot for nine months, in an otherwise healthy individual, obstructing easy diagnosis of cutaneous tuberculosis. Diagnosis was confirmed by histopathology.
