Patients were 29-year-old homosexual men and 47-year-old men and women. HIV is positive. Example 1 was admitted to the hospital one week after constipation and buttocks pain due to urgency. Physical examination, no fever, perianal soft abscess, abscess drainage, rectal biopsy for grade II non-Hodgkin’s lymphoma. Case 2. Previous history of Pneumocystis carinii pneumonia with 1 month of rectal pain, tenesmus and rectal bleeding. Physical examination, no fever, red soft perianal. Due to localized pain, anesthesia was performed under anesthesia, a tumor was found on the rectal wall, and biopsy was confirmed as grade II non-Hodgkin’s lymphoma. Two CT examinations showed symmetric thickening of the levator ani muscle and the surrounding tissue, and a concentric thickening of the rectal wall (this thickening was irregular and there were some local nodules).
