Abstract:
Lymphomatoid granulomatosis (LYG) is a rare B-cell lymphoproliferative disorder associated with Epstein-Barr virus (EBV) infection and is frequently associated with immunodeficiency. Pulmonary involvement with angiocentric distribution is the most common clinical manifestation. Diagnosis is confirmed by tissue biopsy, usually from lung lesions. Due to the paucity of reported cases, there is no validated treatment for LYG. Therapeutic options include interferon-alpha, systemic corticosteroids, rituximab, chemotherapy, and autologous hematopoietic stem cell transplantation. We report a case of a 49-year-old man, with human immunodeficiency virus type 2 (HIV-2) infection, who was diagnosed with LYG with lung involvement and had a full remission after treatment with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone).

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...
