Sialolithiasis accounts for the most common etiology of salivary gland obstruction which leads to recurrent painful swelling of the involved gland which often exacerbates while eating. Stones may be encountered in any of the salivary glands but most frequently in the submandibular gland and its duct. Simultaneous sialolithiasis in more than one salivary gland is rare, occurring in fewer than 3% of cases. Seventy to 80% of cases feature solitary stones; only about 5% of patients have three or more stones, the case report which we are presenting here had three submandibular sialoliths involving both the submandibular glands which were removed by intraoral approach and no post-operative complications were noted.
Malignant tumors of submandibular salivary gland are rare in occurrence. Squamous cell carcinoma of salivary glands accounts for about 0.9-4.7% of all salivary gland tumors with a predilection to occur in parotid gland due to perinodal involvement. Primary squamous cell carcinoma of submandibular salivary gland accounts to about 2% of the tumors and hence it is being represented for its rarity.
Craniofacial osteosarcoma is a relatively rare entity comprising about 6.5-7% of all osteosarcomas, whereas it is reported to be one of the most common malignancies of long bones. We present a case of chondroblastic variant of osteosarcoma (COS) of the maxilla in an 18 year-old-girl. She was treated with a subtotal maxillectomy and later referred for adjuvant chemotherapy. The relevant review of literature with regard to clinical, radiographic findings, histopathological similarities to Chondrosarcoma (CS), role of Immunohistochemistry (IHC) and management modalities of Osteosarcoma of jaw bones (OSJ) in comparison with Osteosarcoma of the long bones (OSL) are being presented in this report.
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.
