Value of conventional cytology in the presence of macroscopic lesions of the anal canal
OBJECTIVES: To verify the value of conventional cytology for the diagnosis of macroscopic lesions of the anal canal and to describe the limitations of the samples.METHOD: We evaluated 395 conventional cytology samples obtained by brushing the anal canal of patients (predominantly male, HIV-positive) and compared them to the presence of macroscopic lesions of the anal canal observed under anorectal examination.RESULTS: Of the total, 91.6% of samples were classified as adequate. Cellular elements representative of the anal transformation zone were observed in 63.5% of samples. Sensitivity in the presence or absence of cellularity was 80% and 31%, respectively.CONCLUSION: The study demonstrates the feasibility of using conventional anal cytology in outpatients.
