The origin of the pathogenic endothelial cells in common infantile hemangioma is unknown. We show here that the transcriptomes of human placenta and infantile hemangioma are sufﬁciently similar to suggest a placental origin for this tumor, expanding on recent immunophenotypical studies that have suggested this pos-sibility[North,P.E.,etal.

The placenta is suggested as the site of humoral factors that prepare a niche similar to the function of malignant tumor cells. If the hypothesis proves to be valid, clues for possible treatment are outlined. Mihm MC, Nelson JS. Hypothesis: the metastatic niche theory can elucidate infantile hemangioma …

It reveals that there might be some correlation between infantile hemangioma and placental trophoblast. Various theories regrarding pathogenesis of hemangioma:-The placental theory is attractive because it would explain the programmed life cycle of infantile hemangioma (IH). This theory is based on evidence suggesting that the placenta is closely related to IH. As suggested from Hoeger, the association between hemangiomatosis and chorangioma supports a link between infantile hemangiomas and embolized placental cells, at least in cases of large chorangiomas, such as those observed in his study . Discuss theories that may account for hemangioma-genesis. 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.

Infantile hemangioma placenta theory

Further, infantile hemangioma (IH) shares various histochemical and genetic characteristics with placental endothelial cells; notably, a predictable life cycle of initial proliferation followed by apoptotic involution similarly to that of the placenta. These findings suggest the possibility that the placenta could be the origin site of IH. (2009). Current Theories on the Pathogenesis of Infantile Hemangioma. Seminars in Ophthalmology: Vol. 24, No. 3, pp. 172-177. The origin of the pathogenic endothelial cells in common infantile hemangioma is unknown. We show here that the transcriptomes of human placenta and infantile hemangioma are sufficiently similar to suggest a placental origin for this tumor, expanding on recent immunophenotypical studies that have suggested this possibility [North, P. E., et al.

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. A hemangioma or haemangioma is a usually benign vascular tumor derived from blood vessel cell types. The most common form is infantile hemangioma, known colloquially as a "strawberry mark", most commonly seen on the skin at birth or in the first weeks of life.A hemangioma can occur anywhere on the body, but most commonly appears on the face, scalp, chest or back. We know that they are not inherited and, unlike infantile haemangiomas, they affect males and females equally.

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.
