Because of gravitational forces, the fistula usually terminates on the chin. Anderson,2 in a complete review of the subject, cites the fact that the cutaneous findings may simulate actinomycosis or granuloma pyogenicum.

REPORT OF A CASE  Mr. J. D., 24 yr. old, was first seen on Nov. 14, 1949, with a granuloma pyogenicum located on the midaspect of the chin (Fig. 1).

Past history revealed that the patient had received a blow on the chin during a fight a year previously.On physical examination, no obvious dental defects were found, but roentgenograms demonstrated a large apical abscess surrounding the two lower incisors (Fig. 2).
