Úlcera tropical (fagedênica) é uma doença de pele aguda ou crônica observada nos trópicos e subtrópicos que é caracterizada por necrose de epiderme e tecido superficial subjacente. As úlceras podem cicatrizar espontaneamente, deixando cicatrizes deprimidas regulares, mas às vezes aumentam e entram em uma fase crônica. Úlceras crônicas são frequentemente grandes e irregulares na forma e podem envolver toda a circunferência de um membro. Alterações pseudoepiteliomatosas podem desenvolver-se para um franco carcinoma escamoso. Acredita-se que os organismos de Vincent (Fusobacterium nucleatum e Borrelia vincentii) desempenham um papel patogênico. | |||

Tropical (phagedaenic) ulcer is an acute or chronic skin disease seen in the tropics and subtropics that is characterised 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.
