Incomplete Carney triad--a review of two cases.

A curious association of three rare tumours was described by Carney in 1977. 'Carney's triad' characteristically includes multifocal pulmonary chondroma, gastric stromal sarcoma and extra-adrenal paraganglioma. Patients may exhibit complete or incomplete expression of the triad. Carney acknowledged that, of 79 patients, only 17 possessed all three tumours. We report here two patients with incomplete expression of Carney's triad.
