1/10. Ossified intramuscular hemangioma: multimodality imaging findings.Whereas calcification of hemangiomas is common, ossification is unusual. Multimodality imaging findings of a rare case of an ossified intramuscular hemangioma in the calf of a 24-year-old woman are presented. Radiographic, computed tomographic, magnetic resonance (MR), scintigraphic, and histologic features of this case are reported. The radiologic differential diagnosis of an ossified mass in soft tissue is also discussed.- - - - - - - - - - ranking = 1keywords = hemangioma (Clic here for more details about this article) |
2/10. Invasive basal cell carcinoma with metaplastic bone formation associated with a long-standing dermatofibroma.A nodule present for many years on the right leg of a 77-year-old woman was excised and studied by light microscopy. An invasive keratinizing basal cell carcinoma associated with metaplastic bone formation, arising within a dermatofibroma, was found.- - - - - - - - - - ranking = 369.25599017366keywords = dermatofibroma (Clic here for more details about this article) |
3/10. Heterotopic ossification in the orbit.BACKGROUND: While calcification of orbital hemangiomas has been reported previously, no reports exist of heterotopic ossifications occurring within the orbit. CASE DESCRIPTION: A 30-year-old male presented with spontaneous onset of painless progressive proptosis of the left eye, with diplopia. The preoperative radiologic findings are presented. The lesion was excised completely. The pathologic features and probable causes are discussed. CONCLUSIONS: Heterotopic ossification of the orbit should be considered in the differential diagnosis of an orbital lesion showing radiologic features of calcification or ossification.- - - - - - - - - - ranking = 0.16666666666667keywords = hemangioma (Clic here for more details about this article) |
4/10. Ossifying hemangioma of the temporal bone.Intratemporal vascular tumors are more frequent than has previously been noted. Despite their small size, hemangiomas of the temporal bone are extremely aggressive and produce severe neural deficits. The term ossifying hemangioma is used to denote an intratemporal vascular tumor characterized by new bone formation, which is responsible for the typical honeycomb appearance of these tumors on high-resolution computed tomographic scans. Early resection offers the best chance for good facial recovery in patients with vascular tumors of the temporal bone involving the facial nerve. Our case report supports this observation and emphasizes the importance of incorporating these tumors in the differential diagnosis of patients with persistent facial paralysis.- - - - - - - - - - ranking = 1keywords = hemangioma (Clic here for more details about this article) |
5/10. Ossified skeletal muscle angioma: report of two cases.Ossifying skeletal muscle angiomas are relatively rare occurrences. The preoperative diagnosis is exceedingly difficult, although ossification may be reflected radiologically as a "Swiss cheese" appearance. Two patients are described whose skeletal muscle angiomas contained osseous tissue. The osseus tissue varied from microscopic foci to an abundant amount which was readily recognizable radiologically. The pathologic and radiological features are discussed and these appearances to hemangioma and lymphangioma are presented.- - - - - - - - - - ranking = 0.16666666666667keywords = hemangioma (Clic here for more details about this article) |
6/10. Cavernous hemangioma with bone formation in a child: case report.A 13-year-old girl suffering from seizures who was found to have hemangioma calcificans in the frontal lobe was surgically treated. The favorable postoperative course of our patient as well as reported cases suggest early excision of the lesion if it is located in an accessible area. Histological examination confirmed ossification with marrow in the lesion. The literature regarding ossification in the brain is discussed briefly.- - - - - - - - - - ranking = 0.83333333333333keywords = hemangioma (Clic here for more details about this article) |
7/10. Ossified skeletal muscle hemangioma: radiologic and pathologic features.Skeletal muscle hemangiomas are relatively uncommon tumors in children and young adults. Although the operative management of these lesions may be affected by their vascularity, the correct preoperative diagnosis is often not made. Ossification of these lesions is rare. Two patients are described whose skeletal muscle hemangiomas contained abundant osseous tissue. This was radiologically reflected by the 'swiss cheese' appearance of the tumors. Such an appearance in an ossified soft tissue mass may allow the correct preoperative diagnosis of this condition.- - - - - - - - - - ranking = 1keywords = hemangioma (Clic here for more details about this article) |
8/10. Ossifying capillary hemangioma of the maxillary and ethmoid sinuses - a case report.A rare lesion of the maxillary and ethmoid sinuses, an ossifying capillary hemangioma, is presented. The therapeutic options and our choice of embolization followed one day later by radical surgery under hypotensive, hypothermic anesthesia are discussed. The principles of therapy involved in this lesion apply to the management of any large vascular tumor of the head and neck.- - - - - - - - - - ranking = 0.83333333333333keywords = hemangioma (Clic here for more details about this article) |
9/10. Ossifying dermatofibroma with osteoclast-like giant cells.Dermatofibroma or cutaneous fibrous histiocytoma is a common cutaneous tumor. Rare histologic variants have been described. We report another variant of dermatofibroma characterized by osteoclast-like giant cells with metaplastic bone formation. Clinically the lesion was a small, brown, hard papule of several months' duration on the left anterior leg of a 58-year-old woman.- - - - - - - - - - ranking = 369.25599017366keywords = dermatofibroma (Clic here for more details about this article) |
10/10. hemangioma of the choroid. A clinicopathologic study of 71 cases and a review of the literature.This is a clinicopathologic study of 71 hemangiomas of the choroid. The cases were divided into three groups: Group 1 consisted of 45 cases of solitary choroidal hemangiomas (not related to any systemic disease); Group 2 comprised 17 cases with unequivocal evidence of sturge-weber syndrome; and Group 3 included 9 cases, 6 of which were classified as "probably sturge-weber syndrome." Clinically, many differences were found that established a clear distinction between Groups 1 and 2. Histopathologically, the solitary hemangiomas were well-circumscribed tumors that showed a sharply demarcated pushing margin causing compression of melanocytes and choroidal lamellae. About 70% of these tumors were located temporally (at the posterior pole). In contrast, the lesions in the sturge-weber syndrome showed a diffuse angiomatosis involving more than one-half of the choroid, as well as the episcleral and intrascleral perilimbal plexuses. The cause and pathogenesis of these lesions are discussed.- - - - - - - - - - ranking = 0.5keywords = hemangioma (Clic here for more details about this article) |
