热带崩蚀性溃疡

定义

热带（崩蚀性）溃疡是一种急性或慢性皮肤病，见于热带和亚热带地区，其特征是表皮和皮下浅表组织坏死。溃疡可能自愈，留下规则的凹陷疤痕，但有时会扩大，进入慢性期。慢性溃疡通常较大且形状不规则，可累及四肢整个周身。假上皮瘤样变可发展为弗兰克鳞癌。奋森氏微生物（具核梭杆菌和奋森疏螺旋体）被认为起致病作用。

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. Vincent's organisms (Fusobacterium nucleatum and Borrelia vincentii) are thought to play a pathogenic role.
