Abstract:
Lymphomas are the most common nonepithelial malignancy in the head and neck region. Among these, non-Hodgkin Lymphoma (NHL) is the most prevalent, and diffuse large B-cell lymphoma (DLBCL) is the most common histologic subtype. NHL is known for its propensity for extranodal involvement, which can affect any anatomical location. The presence of perineural spread is frequently encountered in head and neck malignancies, including lymphomas. We report a case of a 40-year-old male with an enlarging infraorbital facial mass with associated erythema, pain, and paresthesia, which was subsequently found to be extranodal DLBCL with retrograde perineural spread along the infraorbital nerve.

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...
