[Unusual clinical presentation of a thoracic form of a malignant dysembryoma. A case report]

We report here the medical history of a patient diagnosed with teratocarcinoma presenting with a pleural mass without mediastinal involvement as well as typical paraneoplastic hypertrophic osteoarthropathy. This atypical observation is discussed as well as data from the literature on thoracic localisations of extragonadal malignant germ cell tumours.
