The term lymphangioma is outdated and newer research reference the term lymphatic malformation. Lymphatic malformations can be macrocystic, microcystic, or a combination of the two. [ 1 ] Macrocystic have cysts greater than 2 cubic centimetres (0.12 cu in), and microcystic lymphatic malformation have cysts that are smaller than 2 cubic ...
Superficial lymphatic malformation is a congenital vascular anomaly of the superficial lymphatics, presenting as groups of deep-seated, vesicle-like papules resembling frog spawn, at birth or shortly thereafter. [1] Lymphangioma circumscriptum is the most common congenital lymphatic malformation.
Lung biopsy showing infiltration of lymphatic tissue. Lymphangiomatosis is a condition where a lymphangioma is not present in a single localised mass, but in a widespread or multifocal manner. It is a rare type of tumor which results from an abnormal development of the lymphatic system .
Lymphohemangioma is a disease characterized by swelling of the lymph nodes and blood vessels.It is variously described as a "mixture of clear fluid and blood-filled cysts", [citation needed] a mass of abnormal swollen veins and lymph nodes, or a tumorous growth of lymph and blood vessels.
Acquired progressive lymphangioma has thin-walled endothelial-lined gaps interspersed between collagen strands. [2] Endothelial cells show positive staining for lymphatic markers as podoplanin (D2-40), LYVE-1, and PROX-1. Additionally, the cells have variable levels of factor VIII, Ulex europaeus agglutinin I, CD31, and CD34. [10]
Currently, the medical field prefers to use the term lymphatic malformation, because the term cystic hygroma means water tumor. [3] Lymphatic malformation is more commonly used now because it is a sponge-like collection of abnormal growth that contains clear lymphatic fluid. The fluid collects within the cysts or channels, usually in the soft ...
[74] [77] Surprisingly, knock-out of VEGF-D in mice has little effect on lymphatic system development. [78] Nevertheless, during tumorigenesis VEGF-D promotes formation of tumor lymphatic vessels and facilitates metastatic spread of cancer cells. [73] [74] However, little is known about a role of abnormal lymphatics and VEGF-D in LAM pathogenesis.
Lymphangiectasia, also known as "lymphangiectasis", [1] is a pathologic dilation of lymph vessels. [2] When it occurs in the intestines it is known as intestinal lymphangiectasia, colloquially recognized as Waldmann's disease in cases where there is no secondary cause. [3]
