Epithelioid hemangioendothelioma (EHE) of the lung is a low-grade malignant tumor of vascular origin initially described under the name intravascular bronchioloalveolar tumor (IVBAT). We present a case of a 44-yr-old Caucasian female with severe radiating back pain, shortness of breath, recurrent malignant pleural effusions, and a negative malignancy workup. Cytopathologic examination of the four pleural fluid specimens revealed large undifferentiated plasmacytoid malignant cells with abundant pink and finely granular cytoplasm, round nuclei, and prominent nucleoli. The differential diagnosis based on the cytologic findings included hepatocellular, adrenal, and renal carcinomas, melanoma, mesothelioma, and neuroendocrine tumors. Electron microscopy performed on a pleural fluid specimen and subsequent histologic examination of pleural and lung biopsies established the diagnosis of EHE.

Epithelioid haemangioendothelioma (EHE) is a rare vascular tumour of intermediate behaviour. It can arise from various sites including the liver, spleen, pleura, or lung. Cutaneous EHE can be primary or secondary. This report describes the case of a 51 year old man who presented with a history of dry cough, shortness of breath, and pleural effusion, and who developed two cutaneous nodules in the anterior abdominal wall a few weeks later. He had a previous history of asbestos exposure. Computed tomography scan showed a left sided pleural effusion and nodular pleural mass. Histology of both the pleural and cutaneous lesions was compatible with EHE. Electron microscopic examination demonstrated the presence of Weibel-Palade bodies. The patient underwent elliptical excision of the metastatic cutaneous nodules after decortication of the primary pleural tumour and adjuvant treatment. A few reports have described metastasis of intrathoracic EHE to the skin. Despite treatment with interferon, the patient developed more cutaneous lesions two years after the initial diagnosis. Even though the tumour has the classic light histological and ultrastructural features of EHE, it behaved in an aggressive manner.
