Giant cell tumour of extensor tendon sheath in index finger: A case study

Abstract

Giant cell tumours of the extensor tendon sheath are rare neoplasms that commonly affect the hand and wrist. This case study presents a detailed analysis of a giant cell tumor located in the extensor tendon sheath of the index finger. The patient, a 33-year-old female, presented with a painless, progressively enlarging mass on the dorso-ventral of her index finger. The clinical examination and histopathological analysis confirmed the diagnosis of a giant cell tumor. Surgical excision of the tumor was performed, and the subsequent histopathological examination revealed characteristic features of a giant cell tumor, including the presence of multinucleated giant cells, mononuclear cells, and hemosiderin-laden macrophages. The patient experienced a favourable postoperative recovery, with no recurrence observed during the follow-up period of six month. This case study highlights the importance of early diagnosis and appropriate management of giant cell tumours of the extensor tendon sheath to prevent potential complications and preserve hand function. It also emphasizes the significance of thorough histopathological examination in confirming the diagnosis and guiding the treatment strategy. Further research and studies are warranted to explore optimal treatment approaches and long-term outcomes for this rare entity.
