Abstract：
We present a patient with Pacinian corpuscle hypertrophy and hyperplasia in the hand and discuss the diagnosis and treatment of this rare condition. A 46-year-old woman presented with radiating pain of the left middle finger. A strong Tinel-like sign was elicited between the index and middle fingers. The patient frequently used mobile phone, with the corner of the phone consistently applying pressure on the palm. The surgery was carried out under the microscope and two enlarged cystic lesions under the epineurium were found in the proper digital nerve. Histologic examination revealed hypertrophied Pacinian corpuscle with normal structure. Postoperatively, her symptoms gradually improved. Preoperative diagnosis of this disease is very difficult. Hand surgeons should keep this disease in mind preoperatively. In our case, we would not have been able to identify multiple hypertrophic Pacinian corpuscles without the microscope. An operating microscope is recommended in a surgery of this nature. Level of Evidence: Level V (Therapeutic).
摘要：
我们介绍了一名手部Pacinian小体肥大和增生的患者，并讨论了这种罕见疾病的诊断和治疗。一名46岁的妇女出现左中指放射状疼痛。在食指和中指之间引起了强烈的Tinel状标志。患者经常使用手机，手机的角落持续在手掌上施加压力。手术在显微镜下进行，在适当的数字神经中发现了神经外膜下两个扩大的囊性病变。组织学检查显示Pacinian小体肥大，结构正常。术后,她的症状逐渐好转。这种疾病的术前诊断非常困难。手外科医生术前应该记住这种疾病。在我们的案例中,如果没有显微镜，我们将无法识别多个肥厚性Pacinian小体。在这种性质的手术中，建议使用手术显微镜。证据等级：V级（治疗）。
