A unique case of transient spontaneous regression complicated with tumor lysis syndrome of T-cell lymphoblastic lymphoma in HIV-infected patient without antiretroviral therapy.
Spontaneous regression in high-grade non-Hodgkin lymphoma is rare. Herein, the authors report the case of a 26-year-old asymptomatic HIV-infected patient presenting with bleeding per gum after a dental extraction. Initially, a complete blood count showed lymphoblasts and thrombocytopenia. Laboratory investigations were compatible with acute tumor lysis syndrome. Without any steroid or chemotherapy, both clinical and laboratory abnormalities were spontaneously returned to normal limits. However, three weeks later he developed generalized lymphadenopathy. A submandibular gland biopsy revealed to be T-cell lymphoblastic lymphoma. This was followed by the second episode of spontaneous tumor lysis syndrome and spontaneous regression of lymphadenopathy again. At this time, he was treated with cyclophosphamide, adriamycin, vincristine, and prednisolone (CHOP) with whole brain irradiation. During seven months of chemotherapy, the physical examination and blood chemistry were normal. Unfortunately, after seven courses of CHOP, the disease rapidly progressed and ultimately lead to his death.
