hyaline vascular type
Introduction
Introduction Transparent vascular type is one of the unexplained reactive lymphadenopathy, which is rare in clinical practice. It is characterized by prominent swelling of deep or superficial lymph nodes. Some cases may be associated with systemic symptoms and/or multiple systemic damage. In most cases, surgical resection is swollen. After the lymph nodes, the effect is good.
Cause
Cause
The cause of CD is unknown. Plasma cell type is thought to be related to infection and inflammation. Some authors suggest that immunomodulatory abnormalities are the initiating factors of CD. Clinically, 25% of central cases are confirmed to be associated with HHV-8 infection, and at least part of CD is considered to be in B cell malignant hyperplasia. Among the dangers, a few multi-center types can be converted into malignant lymphoma, but most cases follow the results did not translate into malignant tumors.

The clinical manifestations of CD are non-specific. If the lymph nodes are obviously swollen, with or without systemic symptoms, the possibility of CD should be considered. The lymph node biopsy can be diagnosed by the typical CD pathological changes mentioned above, that is, the diagnosis of CD must have pathological evidence. Then according to the clinical manifestations and pathology, the classification diagnosis is made. It is also necessary to rule out various possible related diseases before diagnosis.
Diagnosis
Differential diagnosis
Thinning of the vessel wall: Capillary is the blood vessel with the smallest diameter and the widest distribution. They branch and fit into each other. The degree of density of capillary networks in various organs and tissues varies greatly. Metabolic tissues and organs such as skeletal muscle, heart muscle, lung, kidney and many glands have dense capillary networks; tissues with lower metabolism such as bone, For muscle tendons and ligaments, the capillary network is sparse.
Vascular injury: vascular injury is divided into: complete disconnection, partial rupture, contusion of blood vessel wall, tear of endometrial and arterial spasm, hemorrhage, tension hematoma and acute arterial insufficiency (pale, low skin temperature, numbness, dyskinesia, Symptoms of vascular injury such as severe pain and distal arterial pulsation disappeared, such as open blood vessels or insufficient blood supply, interruption and blood flow restriction at the distal extremity.
