[Carney's complex (myxomas, pigmented spots and endocrine hyperactivity). Apropos of a partial form in monozygotic twins].

The authors describe monozygotic twins with right ventricular myxoma, one of whom had cutaneous myxomas, large cell calcifying Sertoli cell tumor of the testis (a lesion which was certainly latent in his brother) and recurrent cardiac myxoma. These elements are manifestations of "Carney's complex". This recently reported inherited syndrome should be recognized by pathologists because of major risk of cardiac myxoma.

[Recurrent polychondritis with renal microaneurysms and segmental necrotizing glomerulonephritis].

The authors report a case of relapsing polychondritis, in a 41 year-old man, with renal complication. Immunofluorescence study of this segmental necrotizing glomerulonephritis showed an important fibrin fixation without immunoglobulins. Selective renal arteriography, preliminary to the biopsy, showed lobular arterial aneurysms.

[Bronchopulmonary manifestations of Horton's disease. Apropos of a case].

A 78 years old woman developed a pulmonary recurrence four years after the diagnosis of temporal arteritis. The lung biopsy showed the same giant-cells granulomatous lesions with central vessels as the initial biopsy. The recurrence in giant cells-arteritis has already been published but the pulmonary involvement had never been illustrated before by histological data.
