Journal of Neurosurgery (113 Suppl) 2010
Abstract
Hypothalamic hamartomas (HHs) are congenital lesions typically presenting with medically refractory epilepsy. Open or endoscopic surgical procedures to remove or disconnect the hamartoma have been reported to be effective but are associated with significant morbidity. The authors of studies on Gamma...

Abstract
Palatal clefts in conjunction with space-occupying lesions of the oral or nasal cavities are of interest because they may represent a developmental etiology of palatal clefts. Epignathus is a rare space-occupying tumor of the nasopharynx that can arise from the upper jaw, palate, and sphenoid. It ca...

Abstract
An asymptomatic 17-month-old male infant was incidentally found to have a hepatic mass measuring 12cm in maximum dimension. The histopathologic appearance of the resected mass was that of a typical mesenchymal hamartoma. Spindle cells that comprised a predominant cellular constituent of the lesion w...

We had another look at a chest X-ray that had been taken 6 years before, we had found a pulmonary nodule of 18 mm in size. The chest X-ray and computed tomography (CT) taken at admission showed a round nodule with calcification in the same site, with increasing in size to 30 mm. The tumor could not...

Abstract
The histogenesis of folliculosebaceous cystic hamartoma (FSCH), including the origin of the frequently associated adipocytes and other mesenchymal components, remains unclear. There are controversial problems regarding FSCH, such as the relationship between FSCH and trichofolliculoma (TF), and the e...

Abstract
Von-Meyenburg complexes (VMCs) have been shown to progress to cholangiocarcinoma (CC) in some cases. Histologic examination in such cases reveals a gradual transition of VMCs to intermediate lesions and finally to CC. The goal of this study was to determine if this histologic progression was also ac...

Abstract
Hypothalamic hamartomas associated with CPP were more likely to contact the infundibulum or tuber cinereum and were larger than hamartomas not associated with CPP. GnRH, TGFalpha, and GnRHR were expressed by all hamartomas studied. Expression of KISS1, GPR54, and GRM1A did not differ significantly b...

Abstract
BACKGROUND: Mesenchymal hamartoma of the chest wall is an extremely uncommon lesion of infants. Radiologic features simulate a malignant neoplasm; however, pathologic examination demonstrates an admixture of fibroblasts, benign cartilage and woven bone. There is a paucity of cytologic reports of thi...

Our results showed 7% of these 460 girls had gonadotropin-independent precocious puberty (GIPP). The other 93% patients had GDPP and 96% of them were idiopathic. Functional ovarian cyst and hypothalamic hamartoma were leading causes of GIPP and organic GDPP, respectively. The presence of undetectabl...
