To the Editor:
—After publication of an article entitled "Extraosseous Adamantinoma," in the March, 1955, issue of the A. M. A. Archives of Surgery, several requests for a review of the slides were received from interested readers throughout the country. After reviewing the slides it was apparent that the majority felt that the tumor was, indeed, an adamantinoma. However, there were some differences of opinion; those disagreeing with the diagnosis maintained that the tumor was an atypical mixed tumor rather than an adamantinoma. It is of interest that there was unanimous agreement amongst the pathologists who read the original surgical sections.Nevertheless, because of the few differences of opinion expressed it would be well to publish this information in a succeeding issue. Thank you for your courtesy and cooperation.
