Sarcoma botryoides is a tumor that occurs predominantly in the urogenital region, chiefly of infants and children. Although it is considered by many to be a form of rhabdomyosarcoma, there has been no dearth of names used in classifying and describing it, as shown by MacFarland,1 who in 1935 collected 119 synonyms.
Sarcoma botryoides is a rare tumor and in an extraurogenital location is even rarer. This is emphasized by the excellent reviews of extraurogenital tumors of this type made by Horn et al.2 and Farinacci et al.3 Neither of these groups refer to a reported case of sarcoma botryoides arising from the anus, and in a further search of the literature and personal communication with pathologists we have not been able to learn of any other instance of sarcoma botryoides in this location.
