Abstract:
A 36-year-old man with a prior diagnosis of primary cutaneous marginal-zone B cell lymphoma presented with newly-developed, small, erythematous papules and nodules on his upper left arm and pink-to-skin-colored, clustered papules on his left forearm. A biopsy specimen and immunohistochemical analysis of the left arm lesions showed a lymphocytic infiltrate which stained positively for CD20 and Bcl-2 and negatively for CD10. A PET-CT scan was negative for any extra-cutaneous manifestations of disease. These clinicopathologic findings are indicative of recurrent localized primary cutaneous marginal-zone B cell lymphoma.

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...
