The keratocystic odontogenic tumor (KCOT), formerly known as odontogenic keratocyst, is a benign developmental odontogenic tumor with many distinguishing clinical and histologic features. Hard tissue deposits, which usually take the form of dystrophic calcifications, cartilaginous tissue, or dentinoid, are uncommon findings in the connective tissue capsule of the KCOT. We report a case of a 33-year-old female with KCOT showing osseous tissue and calcified deposits close to its epithelial lining, which is an extremely rare occurrence. A brief review on the reported prevalence of hard tissue deposits in KCOTs and possible mechanisms that has been implicated in mineralization and bone formation has been discussed.
Abstract:Chondroma is a benign tumor of cartilaginous origin. Nasal septal chondromas are rare and almost always arise from the bony septum. Considering the very rare occurrence of chondroma from anterior part of the septum, we report a case of Chondroma of the nasal septal cartilage in an adult female, who presented with progressive unilateral nasal obstruction. CT scan showed the minimally enhancing lesion from the anterior septum confined to the left nasal cavity. Excision of the mass was done endoscopically. Histopathological examination of the specimen was suggestive of chondroma.
Objectives: Salivary gland neoplasms are uncommon, but they are of much interest and debate because of their remarkable variability in structure, clinical presentation, and behavior. We have studied 56 cases of parotid tumors and shared our views on the diagnosis and management of these rare tumors.
Materials and methods:Fifty-six patients with parotid swelling presented to us over a period of 5 years. Preoperatively, all these patients were evaluated with fine needle aspiration cyto logy (FNAC). Depending on the report, they were subjected to further treatment.Results: out of 56 cases, 44 (79%) were benign and 12 (21%) were malignant. Pleomorphic adenoma being the commo nest benign tumor [32 cases (72%)] and among the malignant tumors, mucoepidermoid carcinoma was the commonest. Parotidectomy is the gold standard treatment for both the benign and malignant parotid tumors.
Conclusion:Parotid tumors are a rare entity. Among which benign tumors are more common than malignant. An accurate diagnosis preoperatively and timely surgical management would reduce the recurrence rate and risk of complications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
