title: Anal and perianal tuberculosis: a report of three cases in 10 years.
abstract: From the computerized pathology record, three cases of anal and perianal tuberculosis were encountered in the Prince of Wales Hospital, Hong Kong during the last 10 years. The clinical history, examination findings and relevant investigations were reviewed retrospectively. Comparison was made with previous literature. Emphasis was put on the diversity of clinical presentations including acute perianal abscess, chronic anal ulcer and fistula in ano. It is concluded that a high index of suspicion is important to ensure an early diagnosis.
