摘要

Objective: We studied the diagnosis and therapy of primary lung diffuse large B cell lymphoma (DLBCL). Meth-ods: Analysis the clinical manifestations, pathologic character and immunohistochemical character of one tung diffuse B cell lymphoma patent. Results: In visual observation, it's a gray irregular Iobulated mass, section was gray, fish-like, and number of necrotic foci. Observed under the microscope, subepithelial respiratory center oocyte-like cells diffuse proliferative, infiltra-tion in lung tissue. Immunohistochemistry: CDJ0 (+), CD790 (+), CD3 (-), CD45RO (-), PCK (-). Conclusion: Diffuse large B cell lymphoma is the most common subtype in non-Hodgkin lymphoma, but the primary lung diffuse large B cell lymphoma is rare. This disease is lack of typical clinical manifestations, so easily misdiagnosed. The diagnosis of diffuse large B cell lymphoma should be based on pathology and immunohistochemistry.
