Supplementary Material for: Infantile Hemangioma-Like Vascular Lesion in a 26-Year-Old Woman after Abortion Karger Publishers 2014 Infantile hemangioma Adult female Abortion 2014-10-18 00:00:00 Dataset https://karger.figshare.com/articles/dataset/Supplementary_Material_for_Infantile_Hemangioma-Like_Vascular_Lesion_in_a_26-Year-Old_Woman_after_Abortion/5126371 A 26-year-old woman (G2P1A1) presented with a 5-week history of multiple red marks on her body after a therapeutic abortion. A physical examination found 15 palpable red marks on her head, neck, chest, arms and legs. Proliferating endothelial cells, which expressed CD31, CD34, von Willebrand factor, but not Glut-1 and merosin, were observed in the lesional area by histopathological analyses. Histocompatibility antigen typing of 2 lesions was identical to a sample from peripheral blood. Accelerated regression was observed in 2 lesions treated by intralesional injection of betamethasone, while spontaneous regression was observed within 9 months in the remaining lesions without any treatment. Rapid growth, spontaneous regression and histological analyses in this case support the diagnosis of ‘infantile hemangioma-like vascular lesion'.
