Abstract:
Sarcoidosis is occasionally accompanied by hematologic malignancies, including cutaneous T-cell lymphoma, called sarcoidosis-lymphoma syndrome. Although the mechanism underlying the induction of lymphomas is still unknown, understanding the immunological background of sarcoidosis could help explain the possible mechanisms of the induction of lymphomas. In this report, we describe a case of sarcoidosis-lymphoma syndrome associated with folliculotropic peripheral T cell lymphoma not otherwise specified, which caused dense infiltration of CD30+ CD163+ tumor-associated macrophages (TAMs) only in the lesional skin. Our present case might suggest the significance of TAMs in developing sarcoid-lymphoma syndrome.

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...

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...
