Multifocal lymphangioendotheliomatosis, also known as congenital cutaneovisceral angiomatosis with thrombocytopenia and multifocal lymphangioendotheliomatosis with thrombocytopenia (MLT), [1] is a skin condition that presents at birth with hundreds of red-brown plaques as large as several centimeters.
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.
Lymphatic malformations are benign slow-flow type of vascular malformation of the lymphatic system characterized by lymphatic vessels which do not connect to the normal lymphatic circulation.
In the past, the diagnosis of "diffuse neonatal hemangiomatosis" included both infantile hemangioma (IH) and multifocal lymphangioendotheliomatosis with thrombocytopenia (MLT). [8] With advances in medicine and vascular anomalies, there is now a differentiation between the diagnosis of IH, which is benign, and MLT, which has a high mortality rate.
Proliferating Angioendotheliomatosis has historically been divided into two groups, (1) a reactive, involuting type and (2) a malignant, rapidly fatal type. [1]: 598 ...
An infantile hemangioma, also called a strawberry angioma, on a child's arm. Angiomas usually appear at or near the surface of the skin anywhere on the body, and may be considered bothersome depending on their location.
Multiple distinct red globules are seen under a microscope, and a finely pigmented network is seen around the periphery. [8] Histologically, microvenular hemangioma is made up of venules with thin walls that branch erratically and have barely noticeable vascular lumina.
The disease is characterized by vitritis and anterior chamber inflammation. Decreased vision due to vitreous inflammation may occur. Unlike multiple evanescent white dot syndrome, multifocal choroiditis is a chronic disorder and macular scarring contributes to severe visual loss. Theories regarding the cause include an exogenous pathogen ...
