Pacinian corpuscles are rapidly adapting mechanoreceptors distributed in the dermis of the fingers and palm of the hand. A neuroma of the pacinian corpuscle is rare and extremely painful, with only a few cases reported in the literature. A 71-year-old man with pain and swelling on his left index finger, initially diagnosed as tenosynovitis resistant to nonsurgical treatment, was referred to our center. During surgery, a cluster of spherical, gray lesions close to the digital nerve was found and excised. The pathological diagnosis was neuroma of the pacinian corpuscles. Two years later, he reported the same clinical findings on his right index finger with no improvement after nonsurgical treatment. During surgery, the same lesions were found and also identified as pacinian corpuscle neuromas.
环层小体是分布于手指和手掌真皮层的快速适应性机械感受器。环层小体神经瘤罕见且极为疼痛，文献中仅有少数病例报道。一名71岁男性，左手食指疼痛肿胀，最初被诊断为非手术治疗无效的腱鞘炎，后转诊至我院。手术中，在指神经附近发现一簇球形灰色病变并切除。病理诊断为环层小体神经瘤。两年后，他右手食指出现同样的临床表现，非手术治疗后无改善。手术中发现同样的病变，也被诊断为环层小体神经瘤。
