Not only atypical anal fissures, but also fissure-like lesions around the anus were collected and classified according to the type of lesion such as rhagades, erosion, fissure, or ulcer. All thirty-nine diseases were briefly commented on according to diagnosis and treatment of their ulcerative lesions.<BR>Such diseases as Crohn's disease, ulcerative colitis, tuberculosis, syphilis, leukemia or anal cancer are well known as diseases which cause refractory anal ulcers. However, it was made clear that there are many other important illnesses or troubles which give rise to intractable anal ulcerations. These illnesses or troubles could be classified into dermatological disease, infectious disease, sexually transmitted disease, rare malignant disease, incurable disease with unknown etiology, iatrogenic disease, and so on.<BR>I think that it will be most important for an anal surgeon to inquire into the cause of anal ulcers with unknown etiology, and to solve the problem of treatment of a postoperative unhealing wound.
