THE LITERATURE dealing with the subject of myoblastoma is found almost exclusively in journals of surgery and pathology. As far as we could determine, there is only one article by Tuta and Schmidt,1 in addition to a specimen presentation by Schmidt2 and a case presentation by Ebert and Slepyan,3 published in the Archives of Dermatology and Syphilology. This paucity in dermatologic literature is surprising, when one considers that the percentage of cases of myoblastoma located in the skin and subcutis amounts to 20.4 per cent (Powell4), second in order of frequency to location on the tongue, which is seen in 37.6 per cent of the cases. We believe that a better acquaintance of dermatologists with this type of tumor will probably reveal a still higher incidence of myoblastoma in the skin. Until now a number of these tumors were diagnosed as xanthoma, which they resemble microscopically.
