Pyoderma Gangrenosum. Presented by Dr. W. Traut Solomayer.
History.—In January, 1962, this 42-year-old white male noted a furuncle-like lesion on the lower left leg. This broke down and formed a large ulcer. He does not remember having had an injury to this area. Several weeks later he was treated by a physician, and there was some improvement for a short time. In 1956, the patient was treated for ulcerative colitis at Walter Reed Hospital. At present the patient has mild bowel symptoms when emotionally upset or when the proper diet is disregarded.
Physical Examination.—The patient was first examined Oct 4, 1962. Over the anterior aspect of the left lower leg were large and small confluent ulcerations with undermined purple-red borders and foul-smelling, yellowish-green pus. There was only occasional slight discomfort.
