Linfoma de células grandes B originado en enfermedad de Castleman: reporte de un caso y revisión de la literatura / Large B-cell lymphoma coexisting with Castleman's disease: report of one case

ABSTRACT

We report a 73-year-old female patient with Castleman's disease coexistent with large B cell type non-Hodgkin's lymphoma in a right axillary lymphadenopathy. An excisional biopsy was performed microscopically, the lymph node revealed the presence of numerous plasma cells and small lymphoid cells characteristic of Castleman's disease. An analysis of another portion of the specimen revealed lymphoid cells with large abnormal nuclei gathered locally that were CDD 79+, CD 38+ and MUM-1+ as well as positive for Kaposi sarcoma-associated herpesvirus and negative for Epstein Barr virus encoded RNA-1 (EBER).
