Neuropathy associated with angioimmunoblastic lymphadenopathy-like T-cell lymphoma

Abstract:
A 75-year-old woman was admitted because of pain and numbness in the extremities and trunk. She subsequently suffered from lymphadenopathy and spiky fever. The immunohistochemical analysis of the biopsied lymph nodes and sural nerve and electrophysiological examination supported a diagnosis of angioimmunoblastic lymphadenopathy-like T cell lymphoma with polyneuropathy. The infiltrating lymphoma cells of the sural nerve and lymph node shared the same phenotype (CD45RO, CD3, CD30 positive). An increased expression of HLA-DR antigen was observed in endothelial and Schwann cells. Chemotherapy with CHOP-Bleomycin markedly relieved her pain. These findings suggest that a direct lymphocytic infiltration in the nerve may be associated with neuropathy in this case.

Lymphoid Cells and Tissues
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...
Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
