چکیده
|
T-cell/histiocyte-rich large b-cell lymphoma is an unusually encountered lymphoid neoplasm of stomach with aggressive course,and is an uncommon morphologic variant of diffuse large b-cell lymphoma. an ulceratedmass,7x5x1 cm in size was observed within the gastrectomy specimen of a 76-year-old female patient. in cross sections,besides mature lymphoid cells displaying t-cell phenotype,a neoplastic formation composed of large,pleomorphic atypical lymphoid cells with,prominent nucleoli,vesicular nuclei and abundant eosinophilic cytoplasm displaying b-cell phenotype were observed. meanwhile,histiocyte-like mononuclear cells and reed-sternberg-like multinuclear cells expressing cd68 and mac387 were also observed. the diagnosis of the case was t cell/histiocyte-rich large b-cell lymphoma. this rarely encountered neoplasm should be kept in mind in the differential diagnosis of primary gastric lymphomas. © 2016,pakistan medical association. all rights reserved.
