恶性潜能未定的斯皮茨样肿瘤

定义

一种梭形细胞和上皮样细胞黑色素细胞肿瘤，其特征足以区分它与良性Spitz痣，从而怀疑其良性性质。这些不典型的特征包括：成年期发育，不对称，大直径（>6，尤其>10mm），显著厚度（特别是皮下延伸），缺乏“成熟”和结节形成，细胞学不典型，高有丝分裂率。

A spindle cell and epithelioid cell melanocytic neoplasm in which there are sufficient features distinguishing it from a benign Spitz naevus to cast doubt on its benign nature. These atypical features include development in adult life, asymmetry, large diameter (>6 and especially >10 mm), significant thickness (particularly subcutaneous extension), lack of “maturation” and nodule formation, cytological atypia and a high mitotic rate.
