Brown tumor represents a terminal stage of bone remodeling process due to an imbalance between osteoclastic and osteoblastic activity. It represents a reparative cellular process, rather than a neoplastic process mostly associated with primary or secondary hyperparathyroidism. Although parathyroidectomy is the first treatment of choice for brown tumors, several cases don't resolve even after normalization of parathyroid hormone levels which leads to surgical intervention. Therefore, to avoid multiple bone surgeries in the same patient, it is crucial to have a conservative approach like targeted therapy which could block certain molecules involved in bone resorption. In this string, we have recognized and quantified three molecules namely sclerostin, MCP-1 and CD73 in brown tumors and correlated their expression with bone resorption pathogenesis and potential therapeutic approach.
Keywords: Brown tumor; CD73; MCP-1; Molecular pathogenesis; Sclerostin.
