ABSTRACT
Tropical ulcer or tropical phagedenic ulcer is a synergistic bacterial infection caused by a combination of organisms, one of which is a Fusobacterium species, known as F. ulcerans, other bacteria which have been implicated include spirochetes and other aerobic and anaerobic bacteria ( Br J Dermatol 1987; 1616:31 -37; Int Rev Trop Med 1963; 2: 267-291). The disease shares striking similarities with cancrum oris (noma) or the veterinary disease, foot rot of sheep. Tropical ulcer is mainly a disease of older children and young adults. It often occurs in clusters of cases.
