Giant cells serve as a characteristic histopathological feature in which of the following conditions______________?
Show answer Hide answer
Answer: C. Brown tumor of hyper parathyroidism
Explanation
The brown tumor of hyperparathyroidism contains multinucleated giant cells within a fibrous stroma. These giant cells closely resemble osteoclasts found during active bone remodeling and resorption processes. Histopathological analysis confirms that this specific lesion is characterized by these distinct giant cells. Hyperparathyroidism causes excessive parathyroid hormone secretion leading to increased systemic bone resorption rates. Brown tumors are non-neoplastic focal bone lesions resulting from altered mineral and skeletal metabolism. The characteristic brown color stems from accumulated vascularity, hemorrhage, and hemosiderin pigment deposits.
Clinicians evaluate serum calcium and parathyroid hormone levels when encountering these jawbone lesions. Correcting the underlying endocrine disorder typically causes the brown tumor to resolve completely. This condition highlights the direct systemic connection between parathyroid gland function and skeletal health. Apthous ulcers are superficial mucosal inflammatory lesions lacking giant cells in their histology. Keratocysts are developmental odontogenic cysts lined with stratified squamous epithelium without osteoclast-like cells. Dentigerous cysts enclose crowns of impacted teeth and display an epithelial lining without giant cells.
