Mucoepidermoid carcinoma is the most common primary malignancy of the salivary glands. Central mucoepidermoid carcinomas are extremely rare in the jaws. Here we report a case of a 19-year-old central mucoepidermoid carcinoma in a young female patient which was asymptomatic throughout her history and which radiographically simulated a fibro-osseous lesion; both features misled the clinical diagnosis. A radiographic picture of mixed radiopaque-radiolucent appearance in central mucoepidermoid carcinoma is extremely rare. The long duration is also uncommon for a malignant lesion. This case report adds a new dimension to the clinical and radiographic picture a central mucoepidermoid carcinoma can reveal.
Plasma cell myeloma (PCM) is a clonal neoplastic proliferation of terminally differentiated B lymphocytes (plasma cells/myeloma cells) that involves the skeletal system in a multifocal fashion. Even though jaw involvement has been reported in as many as 30% of cases, myeloma cells infiltrating into the pulpal tissue is extremely rare. Here, we present a case of PCM in which myeloma cells are seen infiltrating into the pulpal tissue of 46.
Pleomorphic adenoma (PA) is the most common benign tumor of major salivary glands and intra nasal PA is unusual which may be misdiagnosed as malignancy. A 65-year-old female presented with unilateral nasal bleeding and nasal obstruction in right nasal cavity for 6 months. Local examination showed polypoid mass which surgically excised. HPE showed classic triphasic component of epithelial, myoepithelial with cartilaginous stromal elements and pathological diagnosis of PA made. High cellularity of tumor and predominant squamous epithelial component with keratin pearl created diagnostic confusion of malignancy and it confirmed by immune-histochemistry using p63 to demonstrate presence of myoepithelial component. Highlighted this case report for its unusual location and rare triphasic component of tumor tissue with keratin pearl formation which mimic as malignancy.
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.
