Cutaneous Tuberculosis is a rare form of extra-pulmonary tuberculosis. It is a skin infection typically caused by Mycobacterium tuberculosis. It is more prevalent in TB-endemic areas and immunocompromised individuals. Cutaneous TB has various manifestations and can resemble a multitude of other skin conditions. The disease can be further classified by the route of infection and the bacillary load, which adds another layer of complexity to the diagnostic process. Awareness of cutaneous TB can prompt earlier initiation of microbiological and histopathological workup for the disease, thereby preventing complications and facilitating more effective management. In this report, we present an interesting case of cutaneous TB that manifested as a chronic non-healing ulcer of the foot for 15 years in a healthy middle-aged individual without any risk factors or systemic symptoms.
