We report here a rare case of epithelioid hemangioendothelioma (EHE) of mandible in an adult male, who presented to our department with a huge mass protruding out of the oral cavity. The patient underwent wide local excision of the mass, and histopathological features favored the diagnosis of EHE, which was finally confirmed by immunohistochemistry with CD31 tumor marker.

BACKGROUND Epithelioid hemangioendothelioma (EHE) of the thyroid is an extremely rare disease; only three cases have been reported in the English literature to date. Here, we describe a case involving a patient with thyroid EHE successfully treated with curative surgery. CASE PRESENTATION A 74-year-old woman presented with a right thyroid mass. The nodule was approximately 2 cm in size and wa...

Pulmonary Epithelioid Hemangioendothelioma is a rare and low grade tumor of endothelial origin found in the lungs. At onset patients are usually asymptomatic or present with non-specific symptoms. Chest imaging shows the presence of multiple, bilateral small nodules and diagnosis usually requires a lung biopsy. At this time there is no standardized treatment regimen and the prognosis is variable.

Kaposiform hemangioendothelioma (KHE) is a rare vascular tumor and has a high mortality in newborns when associated with Kasabach-Merritt syndrome (KMS). In two newborns with KHE and severe KMS refractory to medical treatment, emergency embolization led to clinical improvement in the acute neonatal setting by reducing tumor volume, increasing the platelet count, and improving other clotting par...

We report a case of a 76-year-old female with multiple lung nodules (Fig. 1 Rx). Pathologic evaluation of the lower left video-assisted thoracoscopic surgery (VATS) lobectomy VATS-lobectomy showed four nodules that were described as pulmonary epithelioid hemangio-endothelioma (PEH); the immunohistochemical stains showed that the neoplastic cells expressed CD31, a variable expression for factor ...

No standard therapy for pulmonary epithelioid hemangioendothelioma (PEH) has yet been established due to the rarity of the disease, the lack of clear standards for treatment and the partial-to-complete spontaneous regression. This report describes three cases of PHE manifested as bilateral intrapulmonary masses with an initial diagnosis conducted by thoracoscopic lung biopsy. These patients dem...

A new case of epithelioid hemangioendothelioma is reported to have occurred to a 67-year-old patient who consulted for rightsided chest pain. The work-up showed multiple right pulmonary lesions associated with bilateral moderate pleural effusion and left-sided pleural thickening and three hypodense nodules in the right lobe of the liver, peritoneal thickening, ascites, and multiple vertebral ly...

The epithelioid hemangioendothelioma (EH) is an uncommon angiocentric neoplasm of borderline or intermediate malignant potential, between the hemangioma and conventional angiosarcoma. It is characterized by the proliferation of endothelial cells with epithelioid or histiocitóide morphology with vacuolated cytoplasm and occasional eosinophilic spindle cells. Shows potential for local recurrence ...

Infantile hepatic hemangioendothelioma is the most common vascular tumor of the liver in infancy. The diagnosis can be enunciated without histological defnition, if the clinical, analytical and images fndings are very suggestive; particularly in children less than six months old, because the biopsy is not exempt of complications. We report a female patient, four days old and 3500 g, who develop...

Polymorphous hemangioendotheliomas are rare, low-grade borderline malignant vascular tumors of endothelial cell origin. To the best of our knowledge (MEDLINE 1966-2002), there have been nine cases of polymorphous hemangioendothelioma reported in the English literature. Most of the initial patients reported were men, but we present the third case in a woman. Her previous radiation history to the...
