Localized tenosynovial giant cell tumor of the left index finger – a case report

Tenosynovial giant cell tumors (TGCTs) are rare, benign neoplasms of the tendon sheaths, usually affecting the hands. In this case report, a 52-year-old female presented with a painless enlarging mass on the left index finger. Histopathological examination revealed a nodular lesion with foamy histiocytes, multinucleated giant cells, and lymphocytes. Surgical excision led to full recovery with no recurrence. This case emphasizes the importance of considering TGCTs in differential diagnosis of finger masses and highlights surgical excision as an effective treatment.
