Neurothekeoma is a slow-growing, benign tumor of nerve sheath origin. Herein we present a 62-year-old female who presented with a 5-month history of a nodule that had shown a slight enlargement. She had a diagnosis of non-Hodgkin lymphoma for 10 years for which she had received multiple sessions of chemotherapy and radiotherapy. Cutaneous examination showed a well-defined, firm, 2 cm, pink-red nodule of the right supraclavicular area, which showed thick and arborizing vessels under dermoscopy. A diagnosis of cellular neurothekeoma was made after histopathologic examination with immunohistochemistry. Thick and arborizing vessels have been described as the dermoscopic hallmark of nodular and cystic basal cell carcinoma. In the past, hydradenoma and intraepidermal poroma have been defined as dermoscopic mimics of basal cell carcinoma because of the characteristic appearance of arborizing vessels. With this report a neurogenic tumor has been added to this list.
神经鞘黏液瘤是一种生长缓慢的起源于神经鞘的良性肿瘤。在此，我们报告一名62岁女性，她有一个结节，病史5个月，且有轻度增大。她有非霍奇金淋巴瘤病史10年，曾接受多疗程化疗和放疗。皮肤检查发现右锁骨上区有一个边界清晰、质地坚硬、2厘米大小的粉红红色结节，在皮肤镜检查下可见粗大且呈树枝状的血管。经组织病理学检查及免疫组化后诊断为细胞性神经鞘黏液瘤。粗大且呈树枝状的血管已被描述为结节性和囊性基底细胞癌的皮肤镜特征。过去，汗腺腺瘤和表皮内汗孔瘤因具有树枝状血管的特征性表现而被定义为基底细胞癌的皮肤镜模仿病变。通过本报告，一种神经源性肿瘤也被列入了此名单。
