Unusual localization of a malignant fibrous histiocytoma on the mitral valve.

The present report describes the case of a 55-year-old woman who suffered from cardio-embolic stroke originating from malignant fibrous histiocytoma (MFH) localized on the mitral valve. The patient underwent transthoracic two-/three-dimensional and transoesophageal echocardiography which demonstrated the mass protruding in the outflow tract of the left ventricle. Differential diagnosis had to be made with other masses in the left ventricle, such as thrombi, vegetations, and cardiac tumours.

Results, side effects and complications after thoracoscopic sympathetic block by clamping. The monza clinical experience.

Background: Video-endoscopic sympathectomy is the current treatment of choice for severe primary hyperhidrosis. Because of the possible postsurgical side effects, the procedure is carried out using removable endoclips that block sympathetic nerve transmission. This study describes the short and "midterm" side effects and complications of this method for the treatment of palmar, axillary, and facial hyperhidrosis.
