[Thoracic pain, shock-inducing gastrointestinal bleeding].

A 65-year-old patient was referred to hospital with suspected myocardial infarction because of left-sided thoracic pain. A paresis of the left recurrent nerve of unknown etiology has been known for three years. Because of shock with anemia, upper gastrointestinal endoscopy was performed. A diverticulum-like lesion in the proximal esophagus was found to be the source of the bleeding. A contrast X-ray examination showed a cavity of approximately 2 x 2 cm originating from the proximal esophagus. Computerized tomography revealed a large mediastinal mass reaching from the thyroid to the diaphragm. An ultrasound-guided fine-needle puncture of this tumor, together with the endoscopical snare biopsies of the esophageal lesion, allowed the diagnosis of an anaplastic thyroid carcinoma with erosion of the esophagus. The patient responded well to palliative radiotherapy. The defect in the proximal esophagus refilled quickly. Nine months after radiotherapy the patient is doing well.
