Abstract. The relationship between infantile hemangioma (IH) and the placenta has been largely discussed in the last 5 years ( 1 ). North et al documented in 2001 the expression of placental vascular epitopes in hemangiomas, suggesting the origin of these tumors from placental endothelial cells or their precursors ( 2–4 ).

In this study, using the placental origin theory as a basis, we set out to explore whether hemangioma endothelial cells (HEC) were maternal in origin. We rigorously addressed this hypothesis using several molecular genetic techniques. Fluorescent in situ hybridization on surgical specimens of proliferating hemangiomas (n=8) demonstrated no XX-labeled HEC from resected tumors of male infants

Author information: (1)Department for Women and Neonatal Care, Abano Terme General Hospital, Abano, PD, Italy. 2002-08-15 An infantile hemangioma (IH) is a type of benign vascular tumor that affects babies. They appear as a red or blue raised lesion. Typically they begin during the first four weeks of life, grow until about five months of life, and then shrink in size over the next few years. Often skin changes remain following involution.

Extrinsic theory suggests that external environmental factors provide an environment favourable for the development of infantile haemangioma. An infantile hemangioma (IH) is a type of benign vascular tumor that affects babies. They appear as a red or blue raised lesion.

Infantile hemangioma (IH) is the most common benign tumor seen in infancy. This review provides up-to-date information on the pathophysiology, variations in clinical presentation, and natural history of IH, elaborating on associated anomalies, such as PHACE(S) syndrome and LUMBAR syndrome. Because of the benign and

Background: The unique immunobiology of the placental trophoblast and the increased incidence of hemangiomas in infants born after chorionic villus sampling suggest that an immunologically regulated ectopic focus of trophoblasts could be the cell of origin for proliferative infantile hemangiomas. 2008-09-01 · We hypothesize that infantile hemangioma is originated from placental trophoblast, to the specific, placental ECs could embolize and become dislodged into the fetal circulation to receptive tissues during gestation, which can form infantile hemangioma after birth. Clues for the placental trophoblastic origin The higher ratio of placental pathologic findings in patients with infantile hemangioma suggests that reduced placental oxygen diffusive conductance contributes to fetal hypoxic stress and that hypoxic/ ischemic changes in the placenta could be related to infantile hemangioma development via vascular endothelial growth factor and placental growth factor expression, among others, within the villious vessels and thropho- blasts.

How does it work? And is it really 97% accurate? An infantile hemangioma (IH) is a type of benign vascular tumor that affects babies.

This review focuses on the placental theory, which proposes that a fetal placental progenitor is the cell type of origin for infantile hemangioma. The placental theory of hemangioma growth originated from the work developed by North et al (2002) who discovered that the histology and molecular markers unique to placental tissue, namely GLUT1, This review focuses on the placental theory, which proposes that a fetal placental progenitor is the cell type of origin for infantile hemangioma. Special emphasis will be placed on placental vasculogenesis and the presence and transit of placental progenitor cells during gestation. Background: The unique immunobiology of the placental trophoblast and the increased incidence of hemangiomas in infants born after chorionic villus sampling suggest that an immunologically regulated ectopic focus of trophoblasts could be the cell of origin for proliferative infantile hemangiomas.

The pathogenesis of infantile hemangioma is unknown. In recent years, much of the focus has been placed at identifying the cell type(s) responsible for tumor initiation.
