Abstract

<p>A 43-year-old man complained of a subcutaneous mass in the occipital region. The previous doctor attempted puncture and removal, but only partial resection was performed due to bleeding.</p><p>Pathologic examination of resected specimens by the previous doctor raised suspicions of malignant melanoma.</p><p>Craniectomy was performed with a 1.5-cm margin around the back of the black spot. Additional resected skin and sentinel lymph nodes were negative, but the tumor cells grew invasively via blastocyst formation on the skull suture line, and the deep margin was positive. Since dural infiltration was also suspected, the surface of the skull, dura, and cerebral cortex were also subsequently excised ; however, these were negative.</p><p>Although burn scar carcinoma with dural infiltration from the skull suture line has been previously reported, to date there are no reports of malignant melanoma infiltration into the cranium through the skull suture line.[Skin Cancer (Japan) 2017 ; 32 : 202-206]</p>
