An Unusual Presentation of Primary Hyperparathyroidism: Severe Hypercalcemia and Multiple Brown Tumors
Giant cells can also be detected in Aneurysmal bone cysts, Chondroblastoma, Brown tumors
of hyperparathyroidism, Non-ossifying fibroma and Giant cell granuloma.
Primary hyperparathyroidism presenting as a palatal brown tumor
of bone: a potential source of false-positive Thallium-201 localization.
are non-neoplastic lesions found in hyperparathyroidism and can involve the maxilla or mandible.
Furthermore, the radiographic appearance of CGCG is not pathognomonic and may be confused with several other lesions of the jaws, such as brown tumor
of hyperparathyroidism, fibrous dysplasia, aneurysmal bone cyst, and other fibro-osseous lesions.
Based on the radiographic features Gaint cell tumor and Brown tumor
of hyper parathyroidism were thought as probable diagnosis.
Differential diagnosis for lesions that centered within the thyroid or crycoid cartilage includes giant cell reparative granuloma, brown tumor
of hyperparathyroidism, osteoblastoma, chondroblastoma, chondrosarcoma, chondroma, aneurysmal bone cyst, nonossifying fibroma, foreign body reaction, benign fibrous histiocytoma, malignant fibrous histiocytoma, osteosarcoma with abundant giant cells, and carcinoma (including spindle cell or sarcomatoid carcinoma) with giant cells.
We report a case of brown tumor
of the right nasal fossa in a 71-year-old woman.
According to Lessa and his colleagues, brown tumor
can sometimes appear:
Fibro-osseous and giant cell lesions, including brown tumor
of the mandible, maxilla, and other craniofacial bones.
13) GCRG must be differentiated from the brown tumor
of hyperparathyroidism, aneurysmal bone cyst, chondroblastoma, fibrous dysplasia, cherubism, osteosarcoma, and true giant-cell tumor.
We examined a young man who had a benign giant cell granuloma of the maxilla, which we subsequently diagnosed as a brown tumor
associated with hyperparathyroidism.
Extensive brown tumors
caused by parathyroid adenoma in an adolescent patient.
It is possible that patients may develop brown tumors
of bone as a result of proliferation of multinucleated giant cells and osteoclasts.
