Abstract
A 44-year-old female and a 56-year-old male admitted to Okura National Haspital on Decem. 1970 and Feb. 1971 respectively complaining progressive retrosternal pain, dysphagia and fever for several days. They had been taking medicine for long time because of other diseases.
There were no particular findings in their Chest X-rays. But the esophageal rentgenograms approxomately showed a round defect of 10mm diameter and leakage of contrast media outside the esophageal wall. In each esophagoscopic examination a foreign body was found and removed with forceps.
We thought they had misswallowed PTPs with medicine unconsciously We found (1) the pains were produced by their misswallowing PTPs, (2) round defects in the esophageal rentgenograms reflected the pockets of the PTPs (3) and leaking shadows around the round defects were produced by the sharp edges of the PTPs.
