Primer santral sinir sistemi lenfomaları: 10 vakanın retrospektif analizi.

Purpose: Primary central nervous system (CNS) lymphoma, a rare form of non-Hodgkin\u0027s lymphoma (NHL), is defined as high-grade B cell neoplasm of aggressive extranodal CNS. The incidence of CNS lymphoma has been increasing in recent years. In general, it has a poor prognosis. The aim of this study is to evaluate the clinical, pathological, immunohistochemical and radiological features of patients with primary CNS lymphoma in the light of literature. Materials and methods: Between May 2011 and January 2017, 10 patients with pathologic confirmation of primary CNS lymphoma were retrospectively reviewed. Results: Of 10 patients with CNS lymphoma, 7 (70%) were female and 3 (30%) were male. The mean age of all patients at diagnosis was 59.1±13.98 years. The most common settlements; eight patients (80%) had basal ganglia and 3 patients (30%) had multiple intracranial masses. Sterotaxic brain biopsy was performed in 8 patients (80%) and tumor resection was performed by craniotomy in 2 patients (20%). All of the patients with non-Hodgkin B cell lymphoma had diffuse large B cell lymphoma in 10 (100%). All cases had diffuse and strong positivity for CD20. None of the patients had immunodeficiency. Conclusion: Primary CNS lymphoma with a poor prognosis is frequently seen over 55 years of age. Diffuse large B-cell lymphoma is the most common subtype and basal ganglia is the most common site.
