Squamous differentiation in poral adnexal neoplasms is a rare event. Two cases are presented of malignant eccrine poroma in which areas of squamous differentiation showing the features of squamous cell carcinoma were present. The areas of squamous differentiation were found within the invasive components of the lesions and appeared to result from direct transformation of the poral epithelial cells. A review of the literature on this unusual phenomenon is presented.
皮肤附属器肿瘤中的鳞状分化是一种罕见现象。本文报告了两例恶性小汗腺汗孔瘤，其中存在表现为鳞状细胞癌特征的鳞状分化区域。鳞状分化区域在病变的浸润成分中发现，似乎是由汗孔上皮细胞直接转化所致。本文对关于这一不寻常现象的文献进行了综述。
