Abstract:
Diffuse pulmonary lymphangiomatosis (DPL) is rare in adults. It is characterized by abnormal proliferation, dilatation, and thickening of the lymphatic channels in the lungs, pleura, and mediastinal soft tissue. Here, we report a case of DPL in a young adult man with recurrent productive cough. Chest computed tomography (CT) showed bilateral interlobular septal and peribronchovascular thickening and mediastinal soft tissue infiltration. Lung biopsy through video-assisted thoracic surgery demonstrated proliferation and dilatation of irregular lymphatic spaces, lined by flattened endothelial cells that were positive for CD31, D2-40, and factor VIII-related antigen on immunohistochemical staining. After treatment with propranolol for six months, the chest CT showed improved interlobular septal and peribronchovascular thickening and a unilateral pleural effusion, which turned bloody. Radiologic features can suggest the diagnosis of DPL. Surgical biopsy with adequate section size is critical in the diagnosis. Propranolol might be an effective and safe therapeutic option for patients with DPL.

Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
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...

Development of the Lymphatic System
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
