Ganglions occur commonly in the wrist and arise from the radiocarpal and intercarpal joints. Although ganglions present commonly as masses on the dorsal or volar surface of the wrist, ganglions from wrist joints appear rarely at other locations in the hand. We report 2 cases of ganglions arising from wrist joints that presented as painless masses in the center of the palm without signs or symptoms of median or ulnar nerve compression. Surgical treatment required extensile exposure to trace the proximal stalks to their joints of origin. Knowledge of the possibility that a painless mass in the palm could be a ganglion arising from a joint in the wrist allows proper presurgical planning and informed consent.
腱鞘囊肿常见于腕部，起源于桡腕关节和腕骨间关节。尽管腱鞘囊肿通常表现为腕背侧或掌侧的肿块，但腕关节来源的腱鞘囊肿很少出现在手部的其他部位。我们报告2例腕关节来源的腱鞘囊肿，表现为手掌中央无痛性肿块，无正中神经或尺神经受压的体征或症状。手术治疗需要广泛显露，以追踪近端蒂至其起源关节。了解手掌无痛性肿块可能是腕关节来源的腱鞘囊肿这一情况，有助于进行恰当的术前规划并获得知情同意。
