Melanin impregnation in squamous cell carcinoma (SCC) is an uncommon histological finding. Rare nonmelanocytic entities were previously described as having melanocyte colonization. A 57-year-old Brazilian woman was referred with a pigmented lesion in the lower lip and alveolar ridge with a prior clinical diagnosis of melanoma. The incisional biopsy of the tumor revealed an SCC with strong colonization of melanocytes in the stroma. The authors report a case of an unusual SCC variant and a brief review of the literature.
鳞状细胞癌（SCC）中的黑色素沉着是一种罕见的组织学表现。以前曾描述过罕见的非黑素细胞实体有黑素细胞定植。一名57岁的巴西女性因下唇和牙槽嵴出现色素沉着病变前来就诊，此前临床诊断为黑色素瘤。肿瘤的切开活检显示为SCC，间质中有大量黑素细胞定植。作者报告了一例不寻常的SCC变体病例并对文献进行了简要综述。
