A 22 year old male was admitted with haemoptysis. A chest X-ray showed bilateral confluent alveolar infiltrates. Bronchoscopy revealed blood oozing from all bronchopulmonary segments. Open lung biopsy disclosed bilateral effusions and large necrotizing nodules with pleural adhesions. Histological examination showed tumour cells, which were negative to epithelial and embryogenic markers but posi...

Little is known about prognostic factors in epithelioid hemangioendothelioma (EHE). We aimed to identify prognostic factors among various clinicopathologic and imaging features of thoracic EHEs.Forty-two patients (male:female = 20:22; median age, 49 years) of EHEs with (n = 19) and without (n = 23) thoracic involvement were included. We reviewed electronic medical records for clinical informati...

Kaposiform hemangioendothelioma is a rare vascular tumor and locally aggressive endothelial-derived spindle cell neoplasm, which occurs almost exclusively in infants and adolescents. Radiologically, hemangioendothelioma, including Kaposiform hemangioendothelioma, is seen as a highly vascularized well-enhancing tumor, but no characteristic findings differentiate Kaposiform hemangioendothelioma f...

Infantile hemangioendothelioma is a severe disease with a high mortality. It is characterized by multiple hemangioma affecting the skin and visceral organs. We report that high doses of methylprednisolone pulse therapy improved symptoms and signs of infantile hemangioendothelioma in a male neonate, and completely resolved the hepatic and cutaneous hemangioendothelioma on follow up.

The chest x-ray film a 22-year-old man showed a large right-sided pleural effusion that was grossly hemorrhagic when aspirated. A computerized tomographic scan showed a complex mass with cystic components contiguous with the diaphragm. On thoracotomy the mass was found to be arising from the diaphragm and had the consistency of an organizing hematoma. Pathologic studies showed the mass to be an...

Kaposiform hemangioendothelioma, a rare vascular pediatric tumor often associated with Kasabach-Merritt phenomenon, is characterized by severe thrombocytopenia and consumptive coagulopathy. Kaposiform hemangioendothelioma is a severe disease and may progress quickly, resulting in a high mortality. However, standard treatment regimens for Kasabach-Merritt phenomenon have not yet been established...

Pulmonary epithelioid hemangioendothelioma (PEH) is a rare tumor that occurs among young women and typically presents as bilateral multiple nodules. In the present report, we describe an uncommon case of PEH presented as a single cavitary nodule in a 33-yr-old asymptomatic man. This is the first case of PEH presented as a single cavitary nodule in the English literature. Three years of the foll...
