Abstract：
Mucous cyst is a benign but recurrent lesion. It is located on the dorsal surface of the digital extremity between the distal interphalangeal joint and the base of the nail. The nail is often affected by the cyst because of its topographical proximity. Nail plate deformity may even be the first obvious abnormality indicating the presence of a small mucous cyst or subungual cyst. Mucous cyst is associated with osteoarthritis of the joint, osteophytes probably being the main contributing factor. Surgical treatment by joint debridement and cyst removal is the most effective way of preventing recurrence.
摘要：
粘液囊肿是一种良性但复发性病变。它位于远端指间关节和指甲基部之间的指端背侧表面上。由于其地形接近，指甲经常受到囊肿的影响。指甲板畸形甚至可能是第一个明显的异常，表明存在小的粘液囊肿或指甲下囊肿。粘液囊肿与关节骨关节炎有关，骨赘可能是主要的影响因素。通过关节清创和囊肿切除的手术治疗是预防复发的最有效方法。
