XXXX of the anal ducts. A series of 21 cases.

@entity1 @entity5 @entity292 @entity6713 @entity204 @entity420
The records of 21 @entity1 treated for @entity420 of the anal ducts between 1943 and 1982 were reviewed. The @entity1 were followed until @entity204 or current status in April 1987. The median follow-up period was eight months (range, 3 to 144 months). Fifteen @entity1 had an erroneous diagnosis made at first physician visit resulting in a median doctor's delay of 14 months (range, 3 to 24 months) before correct treatment was carried out. Nine of the @entity5 were localized perianally (ischiorectal space), seven anally, and five in a @entity292 . @entity5 localized anally were significantly smaller and had a significantly shorter history than perianally or @entity292 localized @entity5 (P less than .05 for each localization). Three @entity1 with @entity5 had their diagnosis made accidentally by routine histologic examination of an excised @entity6713 . First examination revealed distant metastases in 13 @entity1 and follow-up examination revealed regional or distant metastases in seven @entity1 . Modes of treatment were wide local excision (N = 3), abdominoperineal resection (N = 3), colostomy (N = 9), and radiotherapy (N = 2). Twenty of the 21 @entity1 died within 18 months due to the @entity5 . One long-term survivor was observed; the @entity1 was alive 12 years after local excision of the @entity5 without evidence of recurrent disease. The crude five- and 10-year survival was only 4.8 percent.
