Diagnosis and Treatment of Perianal Warts in at Risk Patients

Abstract

Introduction: Human papillomavirus (HPV) infection is the most common sexually transmitted infection (STI) in humans today. It is estimated that between 75-80 % of sexually active adults will acquire a genital tract HPV infection before the age of 50. The usual clinical manifestation is anogenital warts.

Objective: To identify the main characteristics of perianal warts in at-risk patients.

Method: A descriptive and observational study was carried out in 64 patients with perianal warts, operated on in the Coloproctology Service of the Comandante Manuel Fajardo University Hospital, over an 18-month period.

Results: The majority of patients were male (70.31 %), and the most common age group was between 30 and 39 years (40.62 %). The most frequent symptoms were skin excoriations (78.12 %), followed by local irritation (75 %). The main associated risk factor was unprotected anal intercourse (70.31 %). The highest percentage corresponded to multiple lesions (76.57 %), 45.32 % were found in both locations, and 67.18 % were less than 1 cm. A total of 71.88 % were diagnosed as condylomatosis, and more than 50 % of the patients presented some degree of dysplasia.

Conclusions: The presence of perianal warts in risk groups and the possible existence of dysplastic lesions guide us to carry out screening in these patients, as they are considered precursors to anal cancer.
