A Case of Mediastinal Dermoid Cyst Containing Pancreatic Tissue, Simulating Intrathoracic Goiter

Author and Disclosure Information


The mere addition of another case of mediastinal dermoid cyst to those already recorded in the literature would hardly seem to be justified.

Since its first appearance the swelling had recurred intermittently in the suprasternal notch and above the sternal end of the right clavicle, remaining for a few days and then subsiding.

At the time of admission the patient complained of shortness of breath, difficulty in swallowing, a slight non-productive cough and hoarseness of the voice. There had been no increased nervousness, no loss of appetite or weight and no gastrointestinal or genitourinary symptoms. The patient was well developed and was not acutely ill. The past and family history revealed nothing of importance.

Physical examination showed a tumor mass about the size of a. . .
