We describe a case of recurrent and intractable giant cell tumor of the tendon sheath (GCTTS). The patient was 40-year-old woman who had suffered tumors in the left middle finger for 20 years, and had undergone surgical excision of the lesions on two occasions. At the time of consultation, diffuse tumors were evident at the proximal interphalangeal (PIP)-metacarpal phalangeal (MP) joint of the left middle finger. At surgery, we found that the tumor extended to the dorsal side of the PIP and the MP joint. The tumor and the tendon sheath were resected, and no recurrence has since been observed for two years. As the tumor showed a complex anatomical form, the previous excisions might have been insufficient. We consider that GCTTS should be subjected to long-term follow-up because of its high recurrence rate, and also the long period until recurrence.
