Keratoacanthoma (KA) is a self-limiting benign epithelial neoplasm. It occurs predominantly on sun-exposed areas of the body and is believed to arise from hair follicle. It shows a unique behavior in being clinically benign and microscopically malignant. Earlier it was considered as a pseudomalignant lesion but now it is believed to be pseudobenign in nature. The most common concern is related to its nosological position at the border of malignancy and benignity. We hereby report a rare case of keratoacanthomatous type of squamous cell carcinoma in an elderly female showing aggressive nature of the lesion. The various terminologies used for KA in the past have also been tabulated.
角化棘皮瘤（KA）是一种自限性良性上皮性肿瘤。它主要发生在身体暴露于阳光的部位，被认为起源于毛囊。它表现出一种独特的行为，临床为良性但显微镜下为恶性。早期它被认为是一种假恶性病变，但现在人们认为其本质上是假良性的。最常见的问题与其在恶性和良性边界的疾病分类位置有关。我们在此报告一例老年女性罕见的角化棘皮瘤型鳞状细胞癌病例，该病变具有侵袭性。过去用于KA的各种术语也已制成表格列出。
