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. OBJECTIVE To compare tissue from infantile hemangiomas with that of other vascular lesions for the...

Omental tumors are most commonly found in the pediatric population, with hemangiomas being one of rarest types. These can occur any organ, a higher prevalence skin and subcutaneous tissue. Although they extremely rare, omental tumors, including hemangiomas, often involve greater omentum. We present case 70-year-old male patient that presented to our hospital abdominal pain, distension, inabilit...

OBJECTIVE The purpose of this study is to investigate whether acoustic radiation force impulse (ARFI) elastography with ARFI quantification and ARFI 2-dimensional (2D) imaging is useful for differentiating hepatic hemangiomas from malignant hepatic tumors. MATERIALS AND METHODS One-hundred-and-one tumors in 74 patients were included in this study: 28 hemangiomas, 26 hepatocellular carcinomas ...

OBJECTIVES The aim of this study was to evaluate the technical and clinical outcomes of using laparoscopic radiofrequency (RF) ablation for treating large subcapsular hepatic hemangiomas. METHODS We retrospectively reviewed our sequential experience of treating 124 large subcapsular hepatic hemangiomas in 121 patients with laparoscopic RF ablation. RESULTS The mean diameter of the 124 heman...

PHACE association is a rare neurocutaneous condition in which facial hemangiomas associate with a spectrum of posterior fossa malformations, arterial cerebrovascular anomalies, cardiovascular anomalies, and eye anomalies. We reported a case of PHACE association in a premature infant showing facial, intracranial, and oropharyngeal hemangiomas with evidence of the Dandy-Walker variant and complic...

H emangiomas on the body surface are traditionally classified into strawberry, sponge, mixed, capillary, and rac-emosum hemangiomas. They were classified into 2 major categories, namely, hemangioma and vascular malformation, by Mulliken and Glowacki 1 in 1982. This was a milestone of progress in the classification of hemangioma. This classification was refined in 1996 and expanded in 2014 by th...

We report a case of an intramuscular lipoma with the following karyotype: 46,XY,t(12;14) (q14–15;q24). To our knowledge, this is the third report of a t(12;14) as a sole abnormality in a lipoma. © Elsevier Science Inc., 1998
