Pacinian corpuscles are mechanoreceptors frequently found between the dermis and subcutaneous tissues of the hands and feet. They are responsible for sensitivity to vibration and pressure. Pacinian corpuscle hyperplasia is a rare cause of induration in the palms of the hands or the soles of the feet, often of unknown origin or occasionally related to neurofibromatosis. It can be characterized by magnetic resonance imaging and is included in the differential diagnosis of anechoic lesions on high-resolution soft tissue ultrasound. The definitive diagnosis is made through histopathologic examination. In this case report, we present the findings of a 29-year-old patient who presented with painful nodules on the palms of both hands, with typical findings on ultrasound and magnetic resonance imaging indicative of Pacinian corpuscle hyperplasia. We also discuss the imaging findings and the differential diagnosis through a non-systematic review. Pacinian corpuscle hyperplasia is a rare condition that can be readily identified by high-resolution ultrasound and magnetic resonance imaging, and it should be considered in the differential diagnosis of hand nodules.
环层小体是一种机械感受器，常见于手足真皮与皮下组织之间。它们负责对振动和压力的感知。环层小体增生是导致手掌或脚底硬结的罕见原因，其病因通常不明，偶尔与神经纤维瘤病相关。它可通过磁共振成像进行特征性诊断，并被纳入高分辨率软组织超声检查中无回声病变的鉴别诊断。最终诊断需通过组织病理学检查确定。在本病例报告中，我们呈现了一名29岁患者的检查结果，该患者双手掌出现疼痛性结节，超声和磁共振成像的典型表现提示环层小体增生。我们还通过非系统性综述讨论了影像学表现及鉴别诊断。环层小体增生是一种罕见病症，通过高分辨率超声和磁共振成像可轻易识别，在手部结节的鉴别诊断中应予以考虑。
