Primary intraosseous carcinoma (PIOC) or Primary intraosseous squamous cell carcinoma (PIOSCC) is a rare carcinoma, which arises within the jaws without connection to the oral mucosa. It was first described by Loos in 1913 as a central epidermoid carcinoma of the jaw. The etiology of this tumor is still not clear. It is a rare case which arises by direct transformation of Odontogenic epithelial rests in the jawbone. The epithelial rests found within the periodontal ligament and alveolar bone. Remnants of the dental lamina and the reduced enamel epithelium surrounding anunerupted/impacted tooth, The present report describes a case of PIOC of mandible arising de novo in a 51-year-old-man, which was initially treated by a general dentist, who misdiagnosed it as a periodontal lesion.

Keratocystic odontogenic tumor (KCOT) comprises a unique pathological entity characterized by aggressive or destructive behavior and propensity to recurrence. Usage of the term odontogenic keratocyst (OKC) had been under a lot of dispute from the time it was introduced in 1956. The World Health Organization (WHO) reclassified this lesion in 2005 as a KCOT and defined it as “a benign uni or multicystic intraosseous tumor of odontogenic origin, with a characteristic lining of parakeratinized stratified squamous epithelium and potentially aggressive, infiltrative behavior.” It may be solitary or multiple. Long standing KCOTs have been reported to transform into primary intraosseous carcinoma (PIOSCC) or an ameloblastoma.

Mucoepidermoid carcinoma (MEC) is an epithelial salivary gland neoplasm. It accounts for<10% of all tumors of salivary glands, whereas it constitutes approximately 30% of all malignant tumors of the salivary glands. It is frequently seen in parotid gland, followed by minor salivary glands. Involvement of minor salivary glands is commonly seen in region of hard palate, soft palate, retromolar region, buccal mucosa, floor of mouth and labial mucosa. Here, we report a case of MEC occurring on the palate in a 44‑year‑old female patient reported with a chief complaint of a painless swelling on the palate for 6 years and further diagnosed and managed as as case of MEC.
