Five cases of dermatofibrosarcoma are reported. All showed features typical of dermatofibrosarcoma protuberans except that in four cases, and a portion of the fifth case, no protusion of the tumor was noted clinically despite the rather advanced stage of growth of the tumor. These lesions resembled morphea or a morpheaform basal cell carcinoma clinically but could be recognized as “dermatofibrosarcoma non‐protuberans” by physicians who had observed a previous case.
