Radical surgery yields poor outcomes in a case of metastatic pulmonary epithelioid hemangioendothelioma.
Case Report (n=1)
This case highlights the rare occurrence of epithelioid hemangioendothelioma metastasizing to the tonsil and the diagnostic challenges associated with it.
Rare tonsillar metastasis from pulmonary EHE warrants diagnostic vigilance; leaves open effective treatments beyond surgery given poor prognosis.
Epithelioid hemangioendothelioma is an extremely rare, difficult-to-diagnose vascular tumor mainly originating from the lung or liver. Primary tumors in the head and neck are very rare. A 40-year-old man admitted for right throat pain had been found in biopsy elsewhere to have squamous cell carcinoma. Based on a diagnosis of mesopharyngeal cancer, he underwent radical surgery, reporting cough, sputum, and hemosputum postoperatively. Epithelioid hemangioendothelioma was first diagnosed histopathologically from a biopsy of scalp tumors. Lung specimens at open biopsy 4 years earlier showed the same histological features indicating he had had epithelioid hemangioendothelioma lesion since that time. We assumed this epithelioid hemangioendothelioma had originated in the lung and metastasized to the right tonsil. These tumors are typically progressive and aggressive, and this patient had a poor prognosis. We discuss tumor features and review them clinically and histologically.

Shiga et al. (2002) conducted a case report in Epithelioid hemangioendothelioma metastasizing to the tonsil (n=1). Radical surgery was evaluated. A 40-year-old man with epithelioid hemangioendothelioma originating in the lung and metastasizing to the right tonsil experienced a poor prognosis following radical surgery.
