[Pleural effusions (chylous or nonchylous) with regional osteolysis: A case evocative of Gorham's disease]

In connection with one case of thoracic localized osteolysis associated to bilateral seral effusion, serohemorrhagic on the right, chylous on the left, the authors recall 13 similar observations. In this localization a pleural effusion is very frequent and specific to it, putting at stake the vital prognosis of the patient. These observations can be compared to multiple osteolyses and be grouped together under the name of "intraosseous capillary ectasies".
