Desmoplastic trichilemmoma is a rare histological variant of a benign tumor of the pilosebaceous hair follicle that often clinically appears as similar in appearance to other cutaneous lesions. Here, an 81-year-old male patient with desmoplastic trichilemmoma found on the left zygoma is presented. During the dermatoscopic evaluation of the neoplasm, crown vessels with radial distribution in the periphery were displayed. Histopathologic evaluation revealed peripheral palisading lobules of tumor cells surrounded by sclerotic hyalinized stroma displacing the vessels of the tumor. This case highlights the value of using dermoscopy for improving the clinical diagnosis of desmoplastic trichilemmoma. These findings highlight a need to further investigate the diagnosis of desmoplastic trichilemmoma when crown vessels are displayed during the clinical evaluation.
促纤维增生性毛鞘瘤是一种罕见的毛囊皮脂腺良性肿瘤的组织学变体，临床上通常与其他皮肤病变外观相似。本文报告了一名81岁男性患者，其左颧骨处发现促纤维增生性毛鞘瘤。在对该肿瘤进行皮肤镜评估时，发现周边有呈放射状分布的冠状血管。组织病理学评估显示，肿瘤细胞的周边栅栏状小叶被硬化透明变性的间质包围，间质使肿瘤血管移位。该病例突出了皮肤镜检查对提高促纤维增生性毛鞘瘤临床诊断的价值。这些发现凸显了在临床评估中出现冠状血管时，有必要进一步研究促纤维增生性毛鞘瘤的诊断。
