title: Leukemic manifestation in a case of alpha-chain disease with multiple polypoid intestinal lymphocytic lymphoma.
abstract: We describe a female aborigine from Taiwan with alpha-chain disease associated with multiple polypoid intestinal lymphocytic lymphoma and leukemic manifestation. Initially, the patient experienced intermittent diarrhea, abdominal pain, and leukemic manifestation. No evidence of bone marrow involvement was found. Alpha-chain protein was demonstrated in the serum. Gastroendoscopy and a series of radiographs of the small intestine revealed multiple polypoid tumors involving the entire length of the small intestine. Duodenal biopsy showed diffuse lymphocytic lymphoma. Immunohistochemical staining of tumor samples revealed features typical of alpha-chain disease. Cytogenetic analysis showed the same abnormal karyotypes of neoplastic clones in intestinal tumor cells and in circulating leukemic cells. The data suggest that alpha-chain disease can present initially with intestinal multiple polypoid lymphocytic lymphoma and leukemic manifestation without evidence of bone marrow involvement. The data also support the homing theory of lymphomas from mucosa-associated lymphoid tissue.
