Cryoablation for airway stenosis caused by malignant pulmonary epithelioid hemangioendothelioma: a case report.

ABSTRACT:

Background

Pulmonary epithelioid hemangioendothelioma (P-EHE) is a rare vascular tumor derived from mesenchymal cells with an incidence of about 1/1 million. The etiology remains unclear, and there are no established treatment guidelines. The tumor can occur in a variety of organs, among which the liver, lung and bone are the most commonly involved, with different clinical manifestations, mainly depending on the organ involved, but none of them is specific. Most epithelioid hemangioendotheliomas are indolent and can achieve long-term survival even without any treatment. The prognosis of patients with primary liver or lung diseases is poor, and P-EHE has the highest mortality rate. Clinical reports of airway stenosis caused by P-EHE are exceedingly rare.
