A unique collision of epithelioid hemangioendothelioma and bronchioloalveolar carcinoma in a 54-year-old Japanese woman
We present a unique collision of epithelioid hemangioendothelioma and bronchioloalveolar carcinoma. A 54-year-old Japanese woman seen for a small nodular shadow on chest X-ray in December 1989 was found in chest computed tomography to have multiple small nodules in bilateral lung fields. At thoracotomy through a median sternotomy, 9 nodules from 0.3 cm to 1.2 cm in diameter detected were all resected. The pathological diagnosis was epithelioid hemangioendothelioma of the lung. A focus of bronchioloalveolar carcinoma 1.4 cm in diameter existed adjacent to the focus of epithelioid hemangioendothelioma in the lingular portion of the left lung. The initial surgical margin was not clear, and a complete lingulectomy was conducted through a left lateral thoracotomy. The patient is currently alive with no evidence of recurrence at 13 years after the first appearance.
