ICD-11 code : EA40;
Preferred Label : Tropical phagedaenic ulcer;
ICD-11 definition : Tropical (phagedaenic) ulcer is an acute or chronic skin disease seen in the tropics
and subtropics that is characterized by necrosis of the epidermis and underlying superficial
tissue. Ulcers may heal spontaneously, leaving regular depressed scars, but sometimes
enlarge to enter a chronic phase. Chronic ulcers are often large and irregular in
shape and may involve the whole circumference of a limb. Pseudoepitheliomatous changes
can develop which may proceed to the development of frank squamous carcinoma. Vincent's
organisms (Fusobacterium nucleatum and Borrelia vincentii) are thought to play a pathogenic
role.;
