Tropical ulcer
Tropical ulcer (also known as Aden ulcer, Jungle rot, Malabar ulcer, and Tropical phagedena) is a lesion occurring in cutaneous leishmaniasis. It is caused by a variety of microorganisms, including mycobacteria. It is common in tropical climates.〔Stedman's Electronic Medical Dictionary〕
Ulcers occur on exposed parts of the body, primarily on anterolateral aspect of the lower limbs and may erode muscles and tendons, and sometimes, the bones.〔Medcyclopedia-Tropical ulcer〕 These lesions may frequently develop on preexisting abrasions or sores sometimes beginning from a mere scratch.〔
==Clinical features==
The vast majority of the tropical ulcers occur below the knee, usually around the ankle. They may also occur on arms. They are often initiated by minor trauma, and subjects with poor nutrition are at higher risk. Once developed, the ulcer may become chronic and stable, but also it can run a destructive course with deep tissue invasion, osteitis, and risk of amputation. Unlike Buruli ulcer, tropical ulcers are very painful. Lesions begin with inflammatory papules that progress into vesicles and rupture with the formation of an ulcer.〔 Chronic ulcers involve larger area and may eventually develop into squamous epithelioma after 10 years or more 〔
