Trichoblastoma is occasionally observed in association with a pre-existing nevus sebaceous in the Korean literature. However, there has been no report on the pigmented type. Herein, we report the first Korean case of a pigmented trichoblastoma arising from the nevus sebaceous on the forehead. A 28-year-old male presented with a dark nodular lesion within a yellowish plaque on the forehead. The surrounding yellowish plaque on the forehead had existed since birth. The central, dark-pigmented nodule began to appear three years ago and enlarged gradually. Histopathologic findings of central pigmented lesion showed heavy melanin deposits within and around the tumor nests. Complete excision was made as treatment.
在韩国文献中，偶尔会观察到毛母细胞瘤与先天性皮脂腺痣相关。然而，关于色素型毛母细胞瘤尚无报道。在此，我们报告首例韩国人前额皮脂腺痣发生的色素型毛母细胞瘤病例。一名28岁男性，前额有一个淡黄色斑块内的深色结节性病变。前额周围的淡黄色斑块自出生就存在。中央深色色素结节于3年前开始出现并逐渐增大。中央色素病变的组织病理学检查结果显示肿瘤巢内及周围有大量黑色素沉积。治疗采取完整切除。
