ObjectiveTo summarize the characteristics, diagnosis, and treatment of acral glomus tumor in order to improve the level of diagnosis and treatment. MethodsThe clinical data from 70 cases of acral glomus tumor treated between June 2004 and October 2013 were analyzed retrospectively. There were 11 males and 59 females with an average age of 41 years (range, 18-67 years). The disease duration ranged from 4 months to 30 years, with a median duration of 5 years. Sixty-nine cases had solitary tumors and only 1 patient had more than 1 lesion. The tumors were located on the finger in 66 patients (67 fingers) and the toe in 4 patients (4 toes); among them, the subungual glomus tumor happened in 44 patients (44 fingers and 1 toe). All patients suffered from paroxysmal pain and pinpoint pain with positive Love's pin test, and 29 patients (28 fingers and 1 toe) had positive cold sensitivity. Fifty-two patients (48 fingers and 4 toes) were found to have glomus tumor according to the high-frequency color doppler ultrasonography. X-ray films revealed depression on the phalanx in 16 patients (14 fingers and 2 toes). ResultsNo patient suffered from delayed incision healing, and infection after surgical treatment. The follow-up time was from 1 month to 9 years and 2 months with a median follow-up time of 20 months. The clinical symptoms disappeared after surgery with no dysfunction or recurrence. ConclusionThe diagnosis of acral glomus tumor is easy because of the typical symptoms:paroxysmal pain, pinpoint pain, and cold sensitivity. High-frequency color doppler ultrasonography may play an important role in the preoperative assessment of glomus tumors with accurate localization.
