Herein, we describe a case of <i>NRAS</i>-mutant melanocytic tumor with a blue nevus-like morphology. A 71-year-old Japanese man presented with a 4.6-mm nodule on his back. Histopathological examination revealed a dense distribution of spindle-shaped melanocytes in the upper dermis and a sparse distribution of dendritic melanocytes in the mid-dermis. The vertical periadnexal extension reached the deep dermis at the center of the tumor. A small junctional component, hyperpigmentation, sclerotic stroma, mild nuclear atypia, and a few mitotic figures were observed. Immunohistochemical examination revealed no PRAME expression and preserved p16 expression. Diffuse RASQ61R immunoreactivity was observed in these tumor cells. Nuclear β-catenin expression was not observed. Targeted RNA sequencing revealed two mutations, <i>NRAS</i> c.182A&gt;G (Q61R) and <i>FGFR2</i> c.-157A&gt;G, but no other pathogenic alterations such as <i>BRAF</i>, <i>GNAQ</i>, <i>GNA11</i>, <i>CTNNB1</i>, <i>PRKAR1A</i>, or <i>IDH1</i> mutations or kinase gene fusions. The histopathology fits that of compound-type blue nevus, which is called “Kamino nevus”; however, this tumor was genetically considered to be on the spectrum of conventional acquired melanocytic nevi but not on that of blue nevi.
