To investigate the diagnosis and microsurgical treatment of hand lymphangioma.

From January 2013 to January 2018, seven cases of lymphangioma of the hand were treated at Xuzhou Renci Hospital, including three males and four females, with an average age of 23.6 years (range, 11-33 years). Four cases were located on the back of the hand, one on the wrist, and two on the fingers. The first symptoms were all a painless mass, measuring from 5.0 cm×6.0 cm×0.5 cm to 11.0 cm×15.0 cm×1.5 cm. The volume of the three masses had the characteristics of fluctuation. All the masses were resected under a microscope, and the incision was sutured directly. The function of the affected limb was evaluated according to the Enneking skeletal muscle tumor function scoring system after operation.

In this group of patients, microsurgery was performed. All the masses were proved to be lymphangioma by postoperative pathology. The average time of operation was 95.5 minutes, and the average time of incision healing was 15.3 days. One case developed incision (1.0 cm×2.5 cm) skin necrosis early after sugery, which healed after dressing change. One case developed lymphatic leakage 3 days after operation, which healed after debridement and suture again. The other five cases had satisfactory incision healing. The seven cases were followed for an average of 25.6 months, and the average score limb function score was 25.3 (range, 17-28), with a rate of excellent or good limb function of 85.7% (6/7).

The symptom of lymphangioma of the hand is usually a painless mass, and the volume of the mass may fluctuate. Microsurgery can preserve the subdermal vascular network of the incision skin, realize the precise resection of the tumor, reduce the injury and recurrence, and be conducive to the recovery of limb function.
