Abstract
- The association of B-cell and T-cell disorders is rare. We report a case with coexisting plasma cell leukemia and anaplastic large T cell lymphoma. It is believed to be the first case reported in the literature. A 49-year man was admitted to the hospital because of indigestion. On the gastrofibroscopic examination, a huge, ulcerofungating mass was detected in the stomach, and Ki-1 positive anaplastic large T-cell lymphoma was diagnosed on the biopsy. On the peripheral blood smear and bone marrow study performed as a part of the staging work-up, plasma cell leukemia was diagnosed. The protein electrophoresis and immunofixation of serum and urine revealed IgG, lamda type monoclonal gammopathy. But in the pleural effusion, the involvement of anaplastic large T-cell lymphoma was noted.
