Introduction: Giant cell tumor of the tendon sheath of the hand (GCTTS) is a benign tumor of unknown cause. The clinical diagnosis is supported by pre-operative imaging. The standard of care is surgical resection along with histological confirmation. It appears as a palpable enlargement that is painless. Although pre-operative imaging and fine-needle aspiration cytology (FNAC) corroborate its suspicion, histology following surgical resection is mostly responsible for establishing its diagnosis. Due to its rarity, a case of GCT of the flexor tendon sheath of the right index finger is reported here.

Case Report: We give an example of a patient with giant cell tumor (GCT) of the flexor digitorum profundus tendon sheath in a male patient who is 18 years old. On examination, a 1.8 × 1.2 × 1.0 cm swelling was seen covering an adjoining tendon on the palmar surface of the right index finger at the middle phalanx. The swelling was well-defined, had a smooth surface, was consistently firm, and could be easily pushed in a sideways direction. An isolated soft-tissue shadow was visible in the affected area of the hand’s X-ray, but there was no bone involvement. As a professional shooter, the patient utilizes his right index finger as a trigger finger.

Conclusion: In adults with hand soft-tissue tumors, GCTTS should be considered as a possible differential diagnosis, especially when there’s any evidence of repeated inconsequential minor trauma. The patient should be monitored to find and treat recurrences.
