[Carney's triad. Apropos of a case of recurrent gastric leiomyosarcoma and bilateral pulmonary chondroma].

Carney's triad is a rare syndrome characterized by gastric leiomyosarcoma, functioning extra-adrenal paraganglioma, and pulmonary chondroma. Twenty-seven cases are reported in literature: the most commonly observed neoplasm is gastric leiomyosarcoma (26/27) followed by lung tumor (22/27), and gastric paraganglioma (15/27). Three patients bearing a gastric leiomyosarcoma developed liver metastases, and 6 had a local recurrence after some years. The occurrence of paraganglioma makes the prognosis worse: 4 deaths from local infiltration, metastases or severe hypertension. The triad only occurred in 9/27 cases, mostly young female patients. A common embryologic origin is difficult to assess. The case of a young female patient with recurrent gastric leiomyosarcoma (12 years later) and bilateral pulmonary chondroma is described. It is important that patients with any of the three tumors be periodically examined.
