Perianal diseases in HIV-positive patients compared with a seronegative population.
OBJECTIVE
The aim of this report was to present our cases showing the prevalence and cause of perianal diseases in human immunodeficiency virus-positive patients.


METHODS
We compared 1,860 human immunodeficiency virus-positive patients to 1,350 human immunodeficiency virus-negative outpatients with perianal diseases, examined from January 1989 to December 1996, and the results obtained with the treatment methods for seropositive patients. Among them, 88.7 percent were males, mostly in the age range from 30 to 50 years old.


RESULTS
Condylomas, ulcers, hemorrhoids, fistulas, fissures, abscesses, and tumors were the most frequently diagnosed diseases. Two or more anal diseases occurred in 16.7 percent of patients. Among the human immunodeficiency virus-negative patients we noticed the same incidence of gender, and most were in the age range of 40 to 60 years old. Hemorrhoids, fistulas, skin tags, and fissures were diagnosed.


CONCLUSIONS
From statistical analysis we may conclude that human immunodeficiency virus-positive patients have more condylomas, ulcers, tumors, fistulas, and abscesses than human immunodeficiency virus-negative patients, who have more hemorrhoids. Incidence of fissures was similar in the two groups.
