RESUMEN La gran mayoria de las anomalias vasculares que se pre-sentan en la infancia pueden diferenciarse mediante un exa-men fisico y una historia clinica exhaustivas. Placental chorioangiomas are benign vascular tumors of placental origin. It is the most common tumor of the placenta and is usually found incidentally. Epidemiology The estimated incidence is at ~1% of all pregnancies 3. Clinical presentation Cole Landry's Story: 2009. Dr. Ramen Chmait performed the the fourth successful procedure worldwide to shrink a congenital cystic adenomatiod malformation (CCAM), a mass of abnormal lung tissue, and release the pressure on Cole's heart thereby giving him a chance at surviving. A hemangioma is a mass comprised of tangled blood vessels and connective tissue. Congenital hemangiomas are present at birth. Capillary hemangiomas are the most common type of hemangiomas. Lymphangioma circumscriptum. The typical history involves a small number of vesicles on the skin at birth or shortly after. In subsequent years, they tend to increase in number, and the area of skin involved continues to expand. Chorioangioma, placental: A benign tumor of a blood vessel in the placenta. Large chorioangiomas can cause complications, including excess amniotic fluid (polyhydramnios), maternal and fetal clotting problems (coagulopathies), premature delivery, toxemia, fetal heart failure, and hydrops (excess fluid) affecting the fetus. Introduction Placental chorioangioma is the most common benign tumor of the placenta. Its incidence is quoted around 1 in 100 placentas and is seen more frequently in multiple pregnancies and in female babies [].Chorioangioma is believed to arise by 16th day of fertilization, although there is no documentation of the tumor in the first trimester [].

Lymphatic malformations or lymphangiomas are benign (non-cancerous) vascular lesions made of fluid-filled spaces (cysts) thought to occur due to abnormal development of the lymphatic system. In general, lymphatic malformations are categorized into macrocystic, microcystic, or combined depending on the size of the cysts; they are also classified in superficial lesions known as lymphangioma Start studying Vascular lesions and hemangioma.
