<p>A 20－year－old male noticed a skin nodule on his scalp, which gradually increased in size. At his first visit, a 5×3 cm elevated reddish nodule with poor mobility was found over the parietal region. A skin biopsy showed spindle－shaped cell proliferation, CD34 positivity, <i>COL1A1－PDGFB</i> fusion gene. The tumor was diagnosed as dermatofibrosarcoma protuberans with fibrosarcomatous changes. CT and MRI showed a subcutaneous nodule near the skin nodule, and suspected periosteal invasion. Mapping biopsy was done with a margin of 20 mm around the lesion, and one site was positive. Another biopsy was done 10 mm away from the positive site ; this was also reported positive. A further biopsy done 10 mm away from the site was finally negative. A resection operation was performed. Resection margins were negative and there was no recurrence. Mapping biopsy may be useful in determining the extent of resection for dermatofibrosarcoma protuberans of the scalp.[<i>Skin Cancer (Japan)</i> 2022 ; 37 : 213－217]</p>
