Hepatic hemangioma, a common benign tumor of the liver, has caused great threats to the public health. Most patients have an excellent prognosis because of the benign nature of hemangioma. On some occasions, spontaneous rupture of hepatic hemangioma is rarely observed in patients. Therefore, a majority of scholars propose that surgery should be restricted to specific situations. In this case, w...

Background: Cervical esophageal hemangioma is a rare benign tumor. Symptoms may include hematemesis, dyspnea, cough, dysphagia, and chest pain. Objectives: To describe a case of a large esophageal hemangioma in order to raise awareness of the condition and highlight the use of a cooperative endoscopic treatment approach by a gastroenterologist and otolaryngologist with excellent results. The li...

The authors present an extremely rare case of an aggressive and progressive vertebral capillary hemangioma of the lumbar spine secondary to a trauma. A 40-year-old man who complained of back and leg pain due to a hemangioma of L1 that had begun a year after the fracture of the same vertebra was subsequently operated on. Due to the profuse bleeding, only a subtotal removal was possible. Histopat...

Infantile hemangiomas are endothelial tumors that grow rapidly in the first year of life and regress slowly during early childhood. Although hemangiomas are well-known vascular lesions, little is known about the mechanisms that cause the excessive endothelial cell proliferation in these most common tumors of infancy. To investigate the molecular basis of hemangioma, we isolated endothelial cell...

Aim. Cavernous hemangioma-like Kaposi sarcoma is a rare morphologic type of Kaposi sarcoma. So far there are no cases in the literature defining the histological features of this morphologic spectrum in detail. In this study we presented two classical-type cutaneous Kaposi sarcoma cases with histologic findings resembling cavernous hemangioma in company with clinical and histopathological data....

abstract background: transpupillary thermotherapy is a new treatment for subfoveal choroidal neovascularization which needs further evaluation. this study was aimed to evaluate the efficacy of transpupillary thermotherapy on regression of occult subfoveal choroidal neovascularization with or without pigment epithelial detachment in patients with age-related macular degeneration. methods: in a c...

A hemangioma of the parapharyngeal space (PPS) is an extremely rare tumor and is responsible for 0.5-1% of all tumors occurring in the PPS. We report a case of PPS venous hemangioma in a 49-year-old woman presenting with diffuse swelling in the submandibular region. A preoperative computed tomography (CT) scan showed a cystic mass with multiple calcifications in the PPS. The calcific nodules we...

Hemangioma, the most common tumor of infancy, is a benign vascular neoplasm of unknown etiology. We show, for the first time to our knowledge, that endothelial cells from proliferating hemangioma are clonal, and we demonstrate that these hemangioma-derived cells differ from normal endothelial cells in their rates of proliferation and migration in vitro. Furthermore, migration of hemangioma endo...

Sclerosing hemangioma of the lung is extremely rare. Herein, a case of sclerosing hemangioma of the lung in a 44-year-old woman is reported. On admission, the patient complained of pain in the left lower neck and upper chest. Chest x-ray revealed a mass in lingular lobe of the left lung. The patient underwent surgery and a mass was removed through left posterolateral thoracotomy. Pathologic fin...

Intraosseous vascular lesions are rare conditions, comprising only 0.5 to 1% of all intraosseous hemangioma tumors. They mainly occur in the second decade of life especially in female. The most common locations are the vertebral column and skull; nevertheless, the mandible is quite rare location. Hemangiomas are benign vasoformative neoplasms of endothelial origin. However, the origin of centra...
