Hemangioma in the nose and nasal sinuses is rare, particularly in the maxillary sinus. Differentiation of hemangioma from malignant tumors is important, because both may be accompanied by bone destruction. With regard to giant hemangioma, this type has a rich blood supply, and surgical treatment requires particular care due to the high risk of massive bleeding and obstructed field of view. Alth...

Hemangioma of the heart, presenting as a primary cardiac tumor is extremely rare; it accounts for approximately 2% of all primary resected heart tumors. In our patient, the tumor was located in the orifice of the right lower pulmonary vein. Few cases of cardiac hemangiomas have been reported to arise from the left atrial (LA) wall. Left atrial hemangiomas, especially those attached to the LA wa...

Mesenteric cavernous hemangioma is a very rare disease. Most patients with mesenteric cavernous hemangioma present with gastrointestinal symptoms, such as bleeding and obstruction (1). In this report, to our knowledg, we describe the first case of mesenteric cavernous hemangioma with urological symptoms (1, 2). A 66-year-old man with severe pain radiating toward his penis during urination visit...

Central hemangioma of the mandible and maxilla is extremely rare. Although the mucosal and soft tissue lesions are readily suspected by their clinical appearance, the intrabony lesions may be difficult to distinguish visually. The clinical and radiographic presentation is relatively nonspecific; therefore, a proper diagnosis has to be made. The management of central hemangioma is difficult beca...

patients of all ages and have a reported prevalence rate of 0.001-0.03% in autopsy series and a rate of 0.15% in echocardiac series (1). The majority of primary cardiac tumors are benign. The most common primary cardiac neoplasm is a myxoma, which accounts for approximately half of all cases. Other benign primary tumors include the papillary fibroelastoma, rhabdomyoma, fibroma, hemangioma, para...

Dumbbell-shaped spinal extradural cavernous hemangioma is rare. The differential diagnosis of dumbbell-shaped spinal tumors based on magnetic resonance imaging includes schwannoma and lymphoma. Here, we report a dumbbell-shaped spinal extradural cavernous hemangioma with intrathoracic growth on T2-3 in a 64-year-old man complaining of right side infrascapular area back pain with no neurologic d...

T he main abnormality of the uveal tract in patients with Sturge-Weber syndrome is diffuse choroidal hemangioma (DCH). Diffuse choroidal hemangioma can lead to a total retinal detachment and secondary neovascular glaucoma. Radiotherapy and photodynamic therapy are currently the preferred methods of treatment. Low-dose lens-sparing radiotherapy or proton beam irradiation can induce tumor regress...

Hemangiomas are tumors formed by hyper-proliferation of vascular endothelial cells. This is caused by elevated vascular endothelial growth factor (VEGF) signaling through VEGF receptor 2 (VEGFR2). Here we show that elevated VEGF levels produced by hemangioma endothelial cells are reduced by the mTOR inhibitor rapamycin. mTOR activates p70S6K, which controls translation of mRNA to generate prote...

Cavernous hemangioma of the lung synonymous with arteriovenous fistula or aneurysm of the lung is generally considered to be a congenital abnormality. According to Lindskog and Liebow,1 at least 60 cases are in the literature. Roentgenologically, cavernous hemangioma has the appearance of a lobular shadow of increased density continuous with hilar vascular shadows. Clinically it is usually asso...

Hemangioma of infancy is a condition that may be associated with significant morbidity. While evidence most supports the use of corticosteroids, there is no well-defined or Federal Drug Administration (FDA)-approved systemic therapy for hemangioma of infancy. All currently used treatments have significant risks. Dramatic improvement of complicated hemangioma of infancy to propranolol was recent...
