Ostéo-arthropathie hypertrophiante pneumique et hémangio-endothéliome épithélioïde pulmonaire chez une adolescente de 15 ans

Abstract

Pulmonary epithelioid hemangioendothelioma is a rare vascular tumor of the lung, that may be revealed by hypertrophic pulmonary osteo-arthropathy. Case report. – A 15-year-old patient was admitted because of a 1-month history of pneumonia associated with clubbing. A hypertrophic pulmonary osteo-arthropathy due to a paraneoplastic syndrome associated with lung epithelioid hemangio-endothelioma was diagnosed. Despite surgical resection and chemotherapy, the patient died 6 months later. Comments. – Hypertrophic pulmonary osteo-arthropathy is a rare syndrome in childhood, and is frequently associated with chronic respiratory failure. Diagnosis is confirmed by long bones proliferative periostitis on standard X-ray examination. Pulmonary epithelioid hemangio-endothelioma is a rare vascular malignant tumor, that spreads from the vascular pulmonary or hepatic tissues. The prognosis is variable, depending on the malignancy of the tumor. In the absence of a chronic cardiorespiratory disease, the diagnosis of a pulmonary hypertrophic osteo-arthropathy in childhood should prompt the search for a tumoral cause.
