The liver, spleen, and lymph nodes in mastocytosis

Abstract:
In systemic mastocytosis the liver, spleen, and lymph nodes may be infiltrated by mast cells, with patterns of infiltration specific for each tissue. This may result in hepatosplenomegaly and enlarged lymph nodes. Extensive involvement with mast cells may also be associated with organ dysfunction. Specifically, in the case of liver, mast cell infiltration may result in fibrosis, portal hypertension, and abdominal ascites. Clinically significant involvement of the liver, spleen, and lymph nodes appears to be more common in patients with aggressive forms of mastocytosis, including those with a hematologic disorder.

This one-way system allows fluids, solutes, and even pathogens to enter but prevents their return to the intercellular spaces.
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...

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...
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...
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...
