A review of the literature reveals that ossification or calcification of the auricular cartilage has been reported infrequently.1 Sherrer,2 after thorough study of his own case and an extensive review of the literature, was able to find only 40 cases reported from 1866 to 1931. His own case added another to the total number recorded by September 1932. In the same year Childrey3 reported 8 cases and in 1938,4 7 additional ones. His article of 19384 cited 61 cases reported over a period of seventy-two years, apparently by 21 observers.
Aside from Fränklel2 and Childrey, each of whom reported 15 cases, only Müller,2 Lubber2 and Osler2 saw more than 1 case. It is also believed that all the patients were white persons with the exception of a Chinese reported on by Childrey.4 The ages of most of the patients ranged from the fifth to the eighth decade.
