The pathology of brown tumor in a-36-year-old man on maintenance hemodialysis

Implication for health policy/practice/research/medical education: The brown tumor is a rare benign tumor developed by autonomous osteoclastic activity in hyperparathyroidism. In this photo-clinic, we present a 36-year-old man on chronic hemodialysis presented with a jaw mass. Radiography of the mandible showed a soft tissue mass lesion. Neck computed tomography showed a lytic lesion. A needle biopsy of the mandible showed a lobular design comprised of groups and clusters of osteoclast-like multinucleated giant cells, hemorrhage, and hemosiderin deposits and vascular fibroblastic stroma that were indicative of the brown tumor.
