Leprosy affects the skin and the nerves.

In the skin, the lesion can be single or multiple. The skin lesions are at first flat and red Then they enlarge, and have irregular shapes. They are paler than your surrounding skin in the centre but are darker around their edges. They can be raised or contain nodules. The characteristic feature is loss of sensation in that particular skin lesion to pain, heat and touch.

Thickened nerves, which can be felt below the skin, is also another feature of leprosy. There may be loss of sensation in the skin and weakness of muscles supplied by that affected nerve.

Patients who have leprosy for the long term may lose their hands or feet due to repeated injury resulting from lack of sensation. Inadequate care of wounds leads to gangrene, and the body tissues then die and become deformed.
