Riley and Johannsen1 state in their "Handbook of Medical Entomology" that a multitude of cases of parasitism of dipterous larvae are on record. However, in The Journal, we were able to find only one case of this kind reported in the last 25 years.2 Descriptions and illustrations of myiasis-producing larvae are very scanty in laboratory handbooks. We report herein a case of human intestinal infestation with larvae of Piophila casei, the first one observed in our clinic.

REPORT OF A CASE  F. R. R., a 44-year-old contractor who had modern sanitary facilities in his home, was admitted to the hospital on July 30. 1951, with complaints of bowel disturbance. In 1944 he had attacks of severe pain in the abdomen, radiating to the back and downward to the left thigh. At this time he had noticed blood and mucus as well as small white "worms" in the stool.
