Pacinian corpuscle hyperplasia is a pathological increase in the size (Pacinian hypertrophy) and/or density of mature Pacinian corpuscles. Although its aetiology and pathogenesis remain unclear, surgery is the main treatment. Here, we report a rare case of Pacinian hypertrophy at the fingertip treated with surgical excision and reconstruction using a reverse digital artery flap. A 47-year-old man presented with injuries to his right little finger, which was wedged in a door while unloading a truck. His fingertip was amputated and stump plasty was performed. However, severe pain persisted at the fingertip for 5 months after the surgery. Therefore, the painful part of his fingertip was resected, and reconstruction was performed using a reverse digital artery flap 6 months after the injury. Haematoxylin and eosin staining of the resected specimen revealed scar tissue with foreign body reaction and mild Pacinian hypertrophy. One year has passed since the injury, and the pain has completely disappeared. The patient regained complete range of motion in his little finger and was able to resume work without any limitations. Surgical excision with sufficient margin and reconstruction with a reverse digital artery flap is a reliable method to relieve pain due to Pacinian hypertrophy at the fingertip.
帕西尼小体增生是成熟帕西尼小体大小（帕西尼肥大）和/或密度的病理性增加。尽管其病因和发病机制尚不清楚，但手术是主要治疗方法。在此，我们报告一例罕见的指尖帕西尼肥大病例，采用逆行指动脉皮瓣手术切除并重建进行治疗。一名47岁男性因右小指受伤前来就诊，他在卸卡车时手指被门夹住。其指尖被截肢并进行了残端整形。然而，术后5个月指尖仍持续剧痛。因此，受伤6个月后，切除了其指尖疼痛部位，并采用逆行指动脉皮瓣进行重建。切除标本的苏木精-伊红染色显示有瘢痕组织伴异物反应及轻度帕西尼肥大。受伤已过去一年，疼痛已完全消失。患者小指恢复了完全活动范围，能够毫无限制地恢复工作。进行足够切缘的手术切除并采用逆行指动脉皮瓣重建是缓解指尖帕西尼肥大所致疼痛可靠的方法。
