Primary malignant lymphoma of the central nervous system. Case report
1Institute of Pathological Anatomy and Histology, First Chair, Perugia University.
Abstract:
We report a case of primary malignant lymphoma of the central nervous system found in a 69-year old woman suffering from Parkinson's disease and hypertension. The CAT scan revealed an ill defined lesion in the left frontal lobe which at surgery appeared as a brownish-black friable neoformation. The histologic exam revealed a proliferation of voluminous round lymphoid cells with 2 or 3 nucleoli often apposed to the nuclear membrane. At the immunohistochemical investigation they were positive for LC and L26 monoclonal antibodies. Malignant centroblastic B-cell lymphoma was diagnosed. All post-surgery investigations excluded the presence of neoplasms in other sites.
