Abstract:
A 47-year-old man presented with epiphora and a mass around the lacrimal sac in his left eye. Imaging studies revealed a favorable diagnosis of sinusitis-related mucocele. However, the pathological study of the excised tumor demonstrated a diffuse large B cell lymphoma. The patient was consequently referred to the oncology department for further management. Malignant lymphomas of the lacrimal sac are rare and they can mimic mucoceles. As such, they should be included in the list of differential diagnoses for lacrimal sac mass.

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...
Detailed Structure and Function of Lymph Nodes
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...
