We compared the pathological diagnoses obtained by anal Papanicolaou (Pap) smear with those obtained by anal biopsy or by surgical excision for 153 men who have sex with men (MSM). Analysis of these paired specimens showed that anal Pap smears were an inaccurate predictor of high-grade anal dysplasia, regardless of human immunodeficiency virus (HIV) serostatus. The presence of any abnormal anal cytological finding indicates a potential for high-grade dysplasia on histological examination of MSM.
Duplication of the rectum is a rare embryologic event, but it should be considered as a possibility when perianal fistulas and abscesses remain resistant to conventional standard surgical treatment modalities over the long term. We report the case of a 57-year-old woman who underwent many operations over 30 years for persistent perianal fistulas. After radiological assay by computed tomography, fistulography, and barium enema studies, we performed surgery to remove a cystic mass in the retrorectal region, which was subsequently found to be a rectal duplication. The patient had an uneventful postoperative course and has been asymptomatic for 3 years.
