摘要

梭形细胞鳞状细胞癌(SCSCC)是一种罕见的侵袭性鳞状细胞癌。它占所有SCC的2%-3%,通常发生在阳光照射的地区,以前的电离辐射部位,或免疫功能低下的个体。这种不常见的亚型以上皮和间质成分的增殖为特征,由于其组织病理学与间质起源的肿瘤或反应性梭形细胞病变相似,因此诊断具有挑战性。SCSCC因其高复发和早期转移的可能性而值得注意。免疫组织化学(IHC)研究在区分SCSCC与其他梭形细胞肿瘤(如梭形细胞粘连增生黑色素瘤、皮肤平滑肌肉瘤和非典型纤维黄色瘤)方面起着关键作用。在此,我们提出一个罕见的病例报告,一个55岁的男性表现为口腔黏膜溃疡增生性生长。

The Chameleon Tumor: Navigating the Diagnostic Pitfalls of Spindle Squamous Cell Carcinoma.

Spindle cell squamous cell carcinoma (SCSCC) is a rare and aggressive variant of squamous cell carcinoma (SCC). It accounts for 2%-3% of all the SCC and usually arises over sun-exposed areas, prior ionizing radiation sites, or immunocompromised individuals. This uncommon subtype is characterized by the proliferation of both epithelial and mesenchymal components, making diagnosis challenging due to its histopathological resemblance to neoplastic or reactive spindle cell lesions of mesenchymal origin. SCSCC is noteworthy for its high potential for recurrence and early metastasis. immunohistochemistry (IHC) studies play a critical role in differentiating SCSCC from other spindle cell neoplasms, such as spindle cell desmoplastic melanoma, cutaneous leiomyosarcoma, and atypical fibroxanthoma. Herein, we present a rare case report of a 55-year-old male presenting with ulceroproliferative growth on buccal mucosa.
