The association of connate, left-sided, extensive epidermal verrucous nevus, multiple isolated bone tumors and vitamin-D-resistant rickets since childhood seen in a 20-year-old male patient corresponded to an epidermal nevus syndrome (ENS). However, other organ involvement occasionally associated
Although the histogenesis of sclerosing hemangioma (SH) of the lung is now thought to be respiratory epithelial in origin, the genetic abnormalities that mediate its development are not known. Because pathophysiology of several syndromes associated with benign tumors may converge on the tuberous
Three cases of so-called pulmonary sclerosing hemangioma have been studied for endothelial markers (alkaline phosphatase, adenosine triphosphatase, factor VIII-related antigen, and Ulex europaeus I lectin), for intermediate filaments (keratin, vimentin), and for carcinoembryonic and epithelial
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
We present eleven patients diagnosed of giant hepatic hemangioma in the last 20 years. The diagnosis was confirmed in all the cases during laparoscopy or laparotomy. The mean age of the patients was 44.9 +/- 8.99; nine of them were women. Only two of the patients complained of abdominal pain. Five
In conclusion, we report the cases of two patients with large hemangiomas of the liver, abdominal pain, increased ESR and fibrinogen, increased serum alkaline phosphatase and gamma-glutamyltransferase activity, and normal white blood cell counts. Clinical and biochemical abnormalities disappeared
Sclerosing hemangioma of the lung (SHL) was investigated immunohistochemically, histochemically and ultrastructurally with reference to cellular components associated with the histologic pattern: cuboidal cells in the papillary type, round cells in the solid type, flat cells in the hemorrhagic type
BACKGROUND
Endothelial cells are important in initiating adhesive processes between circulating cells and extracellular structures and changes in their distribution are believed to be important in many pathologic conditions. Since little is known about the detailed distribution of adhesion molecules
Epithelioid hemangioma (EH) of bone is an intermediate vascular tumor that can be locally aggressive. The optimum management of multifocal EH of bone is not well delineated. We described our experience treating one patient with multifocal EH of bone in an effort to document the effect The study was carried out on a material obtained by a biopsy from 18 children having different types of hemangiomas (capillary, cavernous and combined). Histochemical reactions were applied for the following enzymes: Succenatedehydrogenase (SDH), lactatdehydrogenase (LDH), cytochromoxidase, acid
We determined the diseases associated with extremely high levels of alkaline phosphatase in hospitalized patients. Computerized laboratory records of the Hospital of Saint Raphael identified all inpatients who had elevations of alkaline phosphatase above 1,000 U/l from April 1994 to September 1995.
BACKGROUND
We describe 6 cases of a poorly recognized vascular neoplasm that can simulate angiosarcoma.
METHODS
Cases of a rare vascular tumor with a proclivity for the genitourinary tract encountered in our consultation material were prospectively collected between the year 1999 and 2008. Follow-up
To evaluate the value of a three dimension (3D)visualization operative planning system in ultrasound-guided percutaneous microwave ablation (US-PMWA) for large hepatic hemangiomas (LHHs).Fifty-eight patients with LHHs were divided into 3D and 2D groups. The Testicular hemangioma is a very rare neoplasm with only 25 cases reported in the English literature. We describe 8 cases of testicular hemangioma encountered at our institution between 1992 and 2012. Of the 7 consult cases, 4 were malignant, 1 a Leydig cell tumor, and 2 were recognized as
Hemangioma is a benign vascular neoplasm of unknown etiology. In this study, we generated an endothelial-specific PyMT gene-expressing transgenic mouse model that spontaneously develops hemangioma. Based on this transgenic model, a specific binding between PyMT and the core AC dimer of protein
