1/4. Posterior mediastinal capillary hemangioma with extradural extension resembling neuroblastoma.We present two patients with posterior mediastinal capillary hemangiomas that were paraspinal and had intraspinal extension. Computed tomography demonstrated the strikingly hypervascular nature of these tumors, distinguishing them from neuroblastoma.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
2/4. Capillary haemangioma of the testis.A case of testicular capillary haemangioma is reported and the importance of intraoperative examination of this very rare lesion emphasised. Capillary haemangioma of the testis can be similar to malignant testicular tumours on clinical presentation, as well as on ultrasonography and magnetic resonance imaging, and therefore should be included in the intraoperative differential diagnosis. Because of the benign nature of this lesion, conservative surgical treatment by means of tumour enucleation with preservation of the testis is possible, if intraoperative examination of frozen sections of representative tissue can be performed.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
3/4. An infant with Turner-Down aneuploidy and massive capillary hemangioma of the orbit: a case report with review.We report on a case of double aneuploidy involving Down and Turner cell lines in a female child with a massive capillary hemangioma of the left orbit and mild clinical features of down syndrome. Cytogenetic findings with G-banding revealed mosaicism in her peripheral blood, i.e. mos45,X[48]/47,XX, 21[28]/46,XX[12/47,XXX[12]. mosaicism of such nature is rare and to our knowledge the present case is the first reported of Turner-Down double aneuploidy mosaicism associated with an orbital capillary hemangioma. An annotated bibliography of earlier reported cases with documented karyotyping is also included.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
4/4. Surgical excision of periorbital capillary hemangiomas.BACKGROUND: Periorbital capillary hemangiomas of childhood can produce ptosis, strabismus, and anisometropia, resulting in amblyopia. Traditional therapy with either systemic or local corticosteroids occasionally yields incomplete resolution of these lesions and may be associated with numerous adverse complications. The authors report their experience performing surgical resection of periorbital capillary hemangiomas. methods: Twelve children with periorbital capillary hemangiomas were treated surgically. Six of these children had previously failed to adequately respond to steroid injections and six were primarily treated with surgical resection. All lesions were believed to be localized and did not appear to be infiltrative on preoperative computed tomographic scans. RESULTS: All lesions were completely resected, except for two in which there was a small area of residual hemangioma surrounding the lacrimal drainage system that was left intact. Controlled intraoperative hemorrhage in two patients required intraoperative directed-donor blood transfusion. Perioperatively, in one patient a wound dehiscence developed, which required minor repair. This same patient elected to have surgical scar revision postoperatively. The patients have been followed up to 5 years. All did well with improved cosmesis, and they have good lid function. No recurrences have been noted. CONCLUSION: Surgical resection of pediatric capillary hemangiomas should be considered a treatment option in those that fail to respond to corticosteroids and/or are isolated and noninfiltrative in nature.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
