Abstract：
:Primary dural lymphoma is rare, and few of the small number of cases reported to date have been classified using immunohistochemical techniques. To our knowledge, we report the first case of T-cell-rich B-cell lymphoma (diffuse mixed small cell and large cell) presenting as a solitary intracranial dural mass. Cytologic and frozen sections prepared during intraoperative consultation revealed a polymorphic population of lymphocytes suspicious for an inflammatory process. Permanent sections of the dura showed a diffusely infiltrating mass composed of mature lymphocytes peppered with large atypical lymphocytes. Immunohistochemical stains identified the small lymphocytes as T cells (CD3 and CD43) and the large atypical lymphocytes as B cells (CD20). Evidence of rearranged immunoglobulin heavy-chain genes demonstrated B-cell monoclonality. Differentiating between inflammatory and neoplastic lymphocytic masses of the dura obviously has important therapeutic and prognostic significance and may require immunohistochemical and molecular techniques.
