Keratoacanthoma is a common low-grade (unlikely to metastasize or invade) rapidly-growing skin tumour that is believed to originate from the hair follicle and can resemble squamous cell carcinoma.
Keratoacanthoma (KA) 是一种常见的皮肤肿瘤,以其快速生长和自行消退的潜力而闻名。它通常发生在有晒伤史的年龄较大、皮肤白皙的男性身上。虽然使用切除或莫氏显微手术进行手术切除是常用的治疗方法,但还有各种其他治疗选择。 Keratoacanthoma (KA) is a common cutaneous tumor characterized by rapid growth and possible spontaneous regression. It most commonly affects older, fair-skinned males with significantly sun damaged skin. Although surgical removal with excision or Mohs micrographic surgery remains the standard of therapy, there are many alternative therapeutic modalities that can be utilized.
Keratoacanthoma (KA) 是一种低度肿瘤,始于皮肤的某些腺体,在显微镜下看起来与 squamous cell carcinoma (SCC) 类似。关于 KA 是否应归类为侵袭性鳞状细胞癌的一种形式,一直存在争论。 Keratoacanthoma (KA) is a comparatively common low-grade tumor that initiates in the pilo-sebaceous glands and pathologically mimics squamous cell carcinoma (SCC). Essentially, strong debates confirm classifying keratoacanthoma as a variant of invasive SCC. The clinical behavior of KA is hardly predictable and the differential diagnosis of keratoacanthoma and other conditions with keratoacanthoma-like pseudocarcinomatous epithelial hyperplasia is challenging, both clinically and histopathologically.
Cutaneous squamous cell carcinoma (cSCC) 是人类中第二常见的癌症类型,尤其是老年人。手术通常用于治疗鳞状细胞癌,但对于一些无法手术或选择不手术的患者,可以考虑病灶内治疗等其他选择。传统的病灶内治疗 (methotrexate or 5-fluorouracil) 已被使用,但对病灶内免疫疗法和溶瘤病毒疗法等新方法的研究仍在进行中。在本文中,我们将研究 cSCC 的不同病灶内治疗方法,从经典方法到前沿策略。 Cutaneous squamous cell carcinoma (cSCC) is the second most frequent cancer in humans, and it is especially common in fragile, elderly people. Surgery is the standard treatment for cSCC but intralesional treatments can be an alternative in those patients who are either not candidates or refuse to undergo surgery. Classic intralesional treatments, including methotrexate or 5-fluorouracil, have been implemented, but there is now a landscape of active research to incorporate intralesional immunotherapy and oncolytic virotherapy into the scene, which might change the way we deal with cSCC in the future. In this review, we focus on intralesional treatments for cSCC (including keratoacanthoma), from classic to very novel strategies.
在显微镜下, 角化棘皮瘤 (keratoacanthoma) 与鳞状细胞癌非常相似。虽然一些病理学家将 角化棘皮瘤 (keratoacanthoma) 归类为一种独特的实体而非恶性肿瘤,但约 6% 的临床和组织学 角化棘皮瘤 (keratoacanthoma) 确实进展为侵袭性和侵袭性鳞状细胞癌。
