[A case of anal Burkitt's lymphoma]

[Spinal cord compression secondary to metastasis of gingival Burkitt lymphoma revealing a case of HIV infection in Morocco]

Burkitt lymphoma in HIV-infected patients is seldom seen in the oral cavity, and they are rarely reported in the literature. The clinical manifestations may suggest other tumors or gingival infections, which delays diagnosis and management. Spinal cord involvement is exceptional and only a few cases are reported. We report a case of Burkitt lymphoma in the oral cavity and spinal cord, revealing HIV infection in a 44-year-old patient, who responded well to chemotherapy and antiretroviral treatment and is on remission.

[Ano-rectal symptoms, related to Epstein-Barr Virus-Associated Burkitt's lymphoma in an immunocompetent patient]

We report the case of an immunocompetent 23-year-old Caucasian woman, with symptoms including rectal bleeding, tenesmus and epreint, 6 months after an anal sexual trauma. The rectal examination showed a hardened, inflammatory and painful anal margin, associated with stenosis of the anal canal, suggesting abscess. The neurological examination showed numbing of the chin. Pelvic MRI and CT scan confirmed a bulky posterior tissular pelvic mass more than 7 cm in diameter, infiltrating the rectum and the anal canal. Final diagnosis confirmed by biopsy performed during rectosigmoidoscopy was an Epstein-Barr Virus-Associated Burkitt's lymphoma. Chemotherapy resulted in rapid regression of the tumoral mass.
