Abstract: Aplastic anemia (AA) patients with prolonged immunosuppression have a risk of development of lymphoproliferative disorders (LPDs), especially combined with Epstein-Barr virus (EBV) infection. However, development of nature killer/T (NK/T) cell lymphoma, in a nontransplantation setting, has not been documented for AA patients with immunosuppressive therapy (IST). Herein, we described a middle-aged man, Han ethnic, who presented with swelled parotid gland after a long history of IST for AA. Fever, night sweating, weight loss had not been found. Increased heterotypic lymphocytes had been detected in the left side of parotid gland demonstrated as cCD3(+), CD56(+), GranB(+), TIA-1(+), MUM-1(+), KI-67 (50%-75%)(++), Bcl-6(-), MPO(-) by immunohistochemistry, and in-situ hybridization (ISH) indicated EBER positive. Chromosome analysis by R banding method revealed 46, XY [20]. NK/T cell lymphoma concurrent with aplastic anemia was diagnosed and a mild chemotherapy regimen including vincristine, prednisone, L-asparaginase was administered. The parotid mass was gradually regressed after the first cycle of chemotherapy. The patient discharged from the hospital voluntarily and lost the follow-up.
