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....

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...

synovial hemangioma is a rare benign malformation of the synovium. it presents frequently in the knee with pain, tenderness, intermittent swelling and recurrent hemarthrosis. mri can be helpful in diagnosis of synovial hemangioma. in this paper, we present a 45-year-old lady with chronic symptoms and obscure clinical symptoms for 35 years which finally diagnosed and managed arthroscopically as ...

Hemangiomas are the most common tumor of the head and neck in children, including intracranial neoplasms. Capillary hemangioma in turn is the commonest type of hemangioma. Our case establishes that its anatomic distribution may include the intracranial compartment. We were unable to distinguish capillary hemangioma from meningioma based on imaging findings alone.

Hemangiomas are the most common tumor of infantile period and usually involved sites are head and neck (%50), followed by trunk and extremities. Hemangioma is rarely described in genitals. We report a 17-months-old patient with a hemangioma of the preputium penis. The tumor was completely removed surgically and histological examination revealed an infantile hemangioma.

Hepatic hemangioma is the most common benign tumor of the liver. Recently its frequency of detection has increased with the introduction of nation-wide cancer screening programs and technical improvement of radiological modalities such as computed tomography (CT) and ultrasonography. Radiological findings of typical hemangioma are well-known. However, sometimes, there are some atypical findings...

Hemangioma is the most common benign hepatic neoplasm. The majority of cases are asymptomatic and can be confirmed by imaging examinations, including enhanced computed tomography and magnetic resonance imaging. Exophytic growth is not common and pedunculated cases are extremely rare. The present study reports a case that was pre-operatively misdiagnosed as a stomach-originating tumor. Laparosco...
