A 39-year-old black woman noted a pigmented lesion on her right buccal mucosa of which she had been previously unaware. Physical examination revealed a 2.0 X 1.8-cm uniformly pigmented, macular to slightly plaque-like, symmetrically folded, indented lesion. Histologic examination revealed a hyperplastic mucous membrane containing numerous dendritic melanocytes at all levels. No pleomorphism or cytological atypia was recognized and no fibrosis was present in the corium. The case was diagnosed as "melanoacanthoma."
一名39岁的黑人女性注意到其右侧颊黏膜上有一个色素沉着病变，而她之前并未意识到。体格检查发现一个2.0×1.8厘米大小、色素均匀、斑片状至略呈斑块状、对称折叠、有凹陷的病变。组织学检查显示增生的黏膜在各层均含有大量树突状黑素细胞。未发现多形性或细胞异型性，真皮层也无纤维化。该病例被诊断为“黑素棘皮瘤”。
