PURPOSE: This study tvas conducted to report a rare case of anorectal patho logy. METHODS: We report a case of perianal lymphoma in a nonimmunocompromi sed, heterosexual patient and review the literature. RESULTS: A 67-year-old white male was found to have an ulcerated posterior anal mass. Biopsy reve aled large cell lymphoma, B cell type, immunoblastic. There was no dissemin ated disease. The patient denied any homosexual activity and was HIV negati ve. There was complete resolution with chemotherapy (cyclophosphamide, doxo rubicin, vincristine, and prednisone), and he remained disease free for six years. CONCLUSIONS: Rare anorectal pathology may mimic common conditions. Biopsies should be taken to rule out malignancy.
