In the past, it was believed that a mother’s visual impressions or behavior during pregnancy caused the growth of infantile hemangioma in Barnés CMChristison-Lagay EAFolkman J The placenta theory and the origin of infantile hemangioma. Lymphat Res Biol 2007;5 (4) 245- 255 PubMed Google Scholar Crossref 17. Infantile (juvenile) capillary hemangiomas are vascular neoplasms which can appear quite infiltrative histologically and are characterized by cords of cells with areas of marked cellularity. While vessels can be distinguished in most cases, there are many cells which do not appear to be endothelial in origin. The placenta is suggested as the site of humoral factors that prepare a niche similar to the function of malignant tumor cells.

Certain aspects of the biology of infantile hemangioma cells suggest a relationship to the placenta as a possible site of origin for the hemangioma precursor cells. In this article, a relationship between the placenta, with or without a chorangioma and the hemangioma sites of localization, is hypothesized.

Both embryonic and extra-embryonic tissues have been postulated as potential sources for these progenitor cells. 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.

Barnés CM (1), Christison-Lagay EA, Folkman J. 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. New discoveries in infantile hemangioma suggest an involvement of progenitor cells in the pathogenesis of this vascular tumor.

Infantile hemangioma (IH) is the most common benign tumor seen in infancy. similarity between the placenta and IH[23]. Therefore, embolization theory are the failed attempts to detect the presence of maternal–fetal chimerism in IH tissue[28]. 2001-03-15 The relative incidence of hemangioma among infants with lower birth weights climbs to 22% especially among infants having less than 1.5 kg of birth weight [4]. The risk of developing infantile hemangioma is relatively increased with older maternal age, uncontrolled preeclampsia, and maternal placenta previa [5]. 2010-03-17 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.
