Giant cell tumor of the tendon sheath (GCTTS) is a slow growing, firm nodule most commonly found on the fingers. In one review of 64 cases [G Chir. 2013;34:149], the average age was 45 (range 15 to 77 years). There were 40 females and 24 males, with a male to female ratio 1:1.66. The most frequent location of the tumor was:


A slow growing, firm, papulonodule in the flexor side of a finger of an adult (30-50 years) is characteristic.


Referral to a hand surgeon for excision is appropriate.
