Abstract

Keratoacanthoma (KA) is currently considered a benign epithelial neoplasm. We report a patient with a lesion diagnosed as a KA that behaved aggressively like a squamous cell carcinoma (SCC). Similar reports are not uncommon in the literature. Because there are currently no criteria by which KA can be differentiated from SCC in all instances, we prefer to group KAs within the spectrum of well-differentiated SCC. We emphasize excisional surgery as the treatment modality of choice.

摘要

角化棘皮瘤（KA）目前被认为是一种良性上皮性肿瘤。我们报告了一例病变被诊断为KA但表现得像鳞状细胞癌（SCC）一样具有侵袭性的患者。类似的报告在文献中并不少见。由于目前尚无在所有情况下将KA与SCC区分开来的标准，我们倾向于将KA归类于高分化SCC范围内。我们强调手术切除是首选的治疗方式。
