A 58-year-old Japanese female was presented with an endocervical polyp. The polyp was promptly excised, and histological examination revealed distribution of many melanin-loaded spindle-shaped cells in its stromal portion. Immunohistochemically, the cells were positive for S100 protein, SOX10, HMB45, and MART-1. Based on the characteristic cellular morphology and immunohistochemical findings, the lesion was diagnosed as a blue nevus, and malignant melanoma was denied. Endocervical blue nevi are relatively rare, and there are some discordance among previous publications about immunoreactivity against HMB45 and MART-1. %A Masuko, Sayuri %A Ikura, Yoshihiro %A Kato, Hiroki %A Iwai, Yasuhiro %P 191-194 %9 journal article %R 10.5114/pjp.2016.61458 %U http://dx.doi.org/10.5114/pjp.2016.61458
