Symptoms Of Leprosy

Ulcers And Blisters

An ulcer is a type of sore on the skin and often appears as a reddened area of skin with a depression in the middle. If left untreated, ulcers can invade the deeper skin layers, causing tissue destruction. Ulcers commonly form as a response to a reduced blood flow, which is often seen in various types of infections. In leprosy, ulcers are usually seen on the plantar areas of the feet. Neuropathy caused by the mycobacteria aggravates the constant pressure of walking. Both factors contribute to the formation of plantar ulcers. Ulcers and blisters are common in patients with leprosy. Blisters are fluid-filled sores on the skin that resemble a small bubble. Blisters can form from friction, such as from a poorly-fitting shoe, or as a response to some damage, such as from a bad sunburn. In leprosy, blisters appear on the skin due to skin cell damage caused by the mycobacteria.
