CASE Report
A 49-year-old man was found to have a round, anterior mediastinal mass on a chest x-ray film taken on Feb 23, 1977. A month earlier, he had experienced an episode of right shoulder pain radiating to the upper sternal region, which was made worse by deep breathing and which subsided spontaneously.
Roentgenographic examination in March 1977 showed no change. Arch aortography and tomography added no new information. Tomograms failed to show calcium within the tumor, and the visualized surrounding
DISCUSSION
Carcinoid tumors occur uncommonly in the thymus.6, 7 They may or may not be associated with Cushing's syndrome, with the syndrome of multiple endocrine adenomatosis, and with other systemic manifestations.1, 3 As with other thymic tumors, they may be clinically silent and found by a routine chest x-ray film, or they may present with symptoms of local invasion.1 These tumors tend to be more aggressive than thymomas, but prolonged survival after local invasion and distal spread is not uncommon.1,
