Giant Cell Tumor or Brown Tumor of a Phalanx in the Hand: A Case Report in a 44-Year-Old Woman

Abstract

Primary hyperparathyroidism is a rare endocrine disease characterized by hypersecretion of parathormone. Giant cell tumor (GCT) of bone arising from a finger phalanx is an extremely rare phenomenon. We introduced patients with tumoral mass in the fifth proximal phalanx of their right hand. Although pathology findings indicated to giant cell tumor, she had hyperparathyroid adenoma and treated by parathyroidectomy. Neoplastic lesions gradually disappeared without further surgical interventions.
