Life-threatening tardive dyskinesia caused by metoclopramide.

A case of severe life-threatening tardive dyskinesia resulting in esophageal and respiratory difficulties due to metoclopramide therapy is presented. A 66-year-old man with a primary diagnosis of clear cell carcinoma of the biliary duct was treated with metoclopramide for gastrointestinal symptoms related to his chemotherapy regimen. The patient initially presented with tremor and rigidity in the upper extremities. On antiparkinsonian therapy, symptoms progressed to hemiballism and involuntary movements of the face, mouth, and tongue, with respiratory and esophageal dyskinesia. Despite discontinuance of metoclopramide, severe tardive dyskinetic symptoms resulted in placement of a gastrostomy tube to maintain nutritional support. This case along with others in the literature should emphasize the need for continuous reevaluation of metoclopramide during long-term therapy, since serious side effects have been reported to occur.

Primary cardiac osteosarcoma: multidisciplinary aspects applicable to extraskeletal osteosarcoma generally.

An osteosarcoma, primary in the right ventricular epicardium, produced pericardial constriction. Intense activity on technetium-99m bone scintigraphy led to a correct preoperative diagnosis. Biopsy of unrepresentative tissue clouded the diagnosis, and autopsy resolved the issue. Several clinicopathologic correlations are presented. Major therapeutic advances mandate early recognition of extraskeletal osteosarcoma, and the topic is reviewed in regard to cardiac cancers in general. The need to biopsy both hard and fleshy areas of unusual tumors is reviewed.
