Introduction: Anogenital human papillomavirus is the most frequent sexually transmitted viral infection in the world. We aim to describe the local demographic data and the clinical characteristics of anogenital wart (AGW).
Methodology: This is a retrospective study on all patients with AGW attended GUM clinic between 2015 and 2020. Data was obtained from case notes and further analysed.
Results: A total of 935 patients with AGW attended GUM clinic between 2015 and 2020.  The mean age was 30.4 years (range 12-84). The male to female ratio was 2.35:1. Majority were Malaysian (97%). Majority of the Malaysian were Malays (61.5%) followed by Chinese (27.7%) and Indian (8.9%). About 5.6% had substance abuse. While majority (57.9%) were heterosexual, 34.8% were homosexual and 6.4% were bisexual. About 59.8% had more than one sexual partner. A quarter was infected with the human immunodeficiency virus. The most frequent site of AGW in male was perianal (52.6%) followed by penis (45.7%), with 20.6% of them had lesions at multiple sites. For female patients, the most frequent site of AGW was posterior fourchette (45.2%) followed by labia minora (33%) with 46.6% had involvement of multiple sites. About 17.6% had other concomitant sexually transmitted infections. Local treatment application included cryotherapy (86.4%), podophyllin (35.3%), tri-chloroacetic acid (26.8%) and imiquimod (2.6%). About 41.5% required combination of these modalities. Nearly 6.2% experienced recurrence. About 2% required surgical intervention.
Conclusions: AGW was more commonly observed in male. The most frequent site of involvement was perianal for male (52.6%) and posterior fourchette in female (45.2%).
