摘要
The clinical histopathological and immuno-phenotypic features in 5 patients with Ki-1 positive non-Hodgkin's lymphoma (NHL) were studied. When firstseen, 4 patients presented enlargement of superficiallymph nodes, with skin lesions in 2 patients. Two patientsin stage Ⅳ with fever, hepato-splenomegaly and bonemarrow invasion, died. Histologically, the tumor cellsshowed diffused or patchy hyperplasia. The cells wererelatively large in size, rich in basophilic or slightlyeosinophilic cytoplasm with irregular-shaped nuclei,prominent nucleoli, and distinct anaplasia andpleomorphism. Some of the cells looked very much likethe Reed-Sternberg cells. Multinucleated giant cells wereseen. Immunophenotypically, all the cells were CD30 (Ki-1) and CD25 (IL-2 receptor) positive but CD15 (Leu M1)negative. Thus, the 5 patients with Ki-1 positive NHLwere all of T cell type.
