Description:This patient presented to a clinical setting with an inflammatory cutaneous lesion on the thorax, which was determined to be the tuberculoid, paucibacillary form of leprosy, or Hansen’s disease. Leprosy is caused by the bacterium, Mycobacterium leprae. Of particular importance are the enlarged costal nerves below the skin that were affected by the disease, and which were supplying the leprous lesion.
The tuberculoid form of leprosy is characterized by one or more solitary cutaneous lesions, which exhibit hypopigmentation, and anesthesia, due to the involvement of the peripheral nerves supplying the region, whereupon, the body’s own immune system attacks these nerves.
