A Case of Brown Tumor of the Hard Palate in Association with Primary Hyperparathyroidism / 대한이비인후과학회지

Brown tumor, also referred as "Oteitis fibrosa cystica," is a focal lesion found within the areas of bone resorption as a result of diffused resorptive process of the bone resulting from hyperparathyroidism. Brown tumors are nonneoplastic tumors of multinucleated giant cells and fibrocellular proliferation. Brown tumors as a part of primary hyperparathyroidism are commonly multiple and occur in the ribs, clavicle, and pelvic girdle. However, brown tumor on the hard palate is extremely rare. We recently experienced a case of a 39-year old female patient with palatal brown tumor. We present this case of brown tumor that occurred after primary hyperparathyroidism with a brief review of literature.

Isolated Sphenoid Sinusitis with Orbital and Intracranial Complication

Sphenoid sinus is adjacent to important intracranial structures, such as major intracranial vessels and some cranial nerves. However isolated sphenoid sinusitis is often misdiagnosed because presenting symptoms are initially subtle. Therefore, if the diagnosis of the isolated sphenoid sinusitis is delayed and complications occur, it will lead to disastrous results. We experienced a rare case in which a 51-year-old male patient developed both brain abscess and abuducens nerve palsy and report this case with a review of the case and related articles.
