Detailed Structure and Function of Lymph Nodes

3.6K
Lymph nodes are bean-shaped structures that cluster along the lymphatic vessels in the inguinal, axillary, and cervical regions. Each node is divided into compartments by a capsule that extends trabeculae inward.
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...

Lymphatic Vessels and Lymph Transport01:16

Lymphatic Vessels and Lymph Transport

21.3K
Lymphatic vessels, known as lymphatics, are crucial in transporting lymph from peripheral tissues to our venous system. This process begins with lymph entering through tiny capillaries that branch through tissues. These capillaries have unique features such as larger diameters, thinner walls, and a distinctive one-way valve system formed by overlapping endothelial cells.
This one-way system allows fluids, solutes, and even pathogens to enter but prevents their return to the intercellular...

Development of the Lymphatic System

1.6K
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
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...

Lymphoid Cells and Tissues

2.3K
Lymphoid cells and tissues are integral to the immune system, which is crucial in maintaining our body's defense against harmful pathogens. They form the building blocks of lymphoid organs, which include the spleen, thymus, and lymph nodes.
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 Organs01:15

Secondary Lymphoid Organs

8.2K
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
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...

Area of Science:

  • Dermatology
  • Vascular Malformations

Background:

  • A novel entity, the net-like superficial lymphatic malformation (LM), has been recently described.
  • This condition exhibits unique clinical, dermoscopic, and histological features.

Purpose of the Study:

  • To report a new case of net-like superficial lymphatic malformation (LM).
  • To highlight an additional, previously undocumented clinical feature associated with this LM subtype.

Main Methods:

  • Clinical examination of the patient.
  • Dermoscopic evaluation of the affected skin.
  • Histopathological analysis of a biopsy specimen, including D2-40 (podoplanin) staining.

Main Results:

  • The case presented with characteristic red to purplish macules and a reticulated vascular pattern.
  • Dermoscopy revealed arborizing telangiectatic vessels.
  • Histology confirmed a superficial vascular proliferation of thin-walled vessels positive for D2-40.
  • An additional finding of hypopigmented macules was observed in this case.

Conclusions:

  • The net-like superficial lymphatic malformation is a distinct vascular anomaly.
  • The presence of hypopigmented areas represents a novel clinical presentation for this LM subtype.
  • Further research is warranted to understand the full spectrum of this condition.
