Introduction: According to the classification of the World Health Organization, primary tumors of the oral cavity can be divided into odontogenic and non-odontogenic, which can be benign or malignant. They arise from mucosal tissue, neurovascular structures and muscles. The most common sites in the oral cavity are the jaws, sublingual area, retromolar area, and hard palate. In 90% of cases, malignant tumors of the oral space are squamous cell carcinomas, which make up 3% of all cancers affecting the body. Other malignant tumors in order of frequency are salivary gland tumors, primary bone tumors and metastatic tumors. According to the available literature, primary adenocarcinomas of the mandible that are not classified elsewhere are extremely rare. Case report: A middle-aged patient presents to the Clinical Department of Oral Surgery, due to non-specific pain on the right side of the neck radiating towards the ear and the inability to open the mouth fully. A clinical examination does not reveal any clear cause of the complaints, but a radiolucent area in the area of the right corner of the mandible is observed by radiological diagnostics. An incisional biopsy showed that it was a clearly differentiated adenocarcinoma of partly salivary and partly papillary morphology. Additional radiological examinations ruled out other organs as potential primary foci and confirmed that it was a primary tumor. The patient underwent a resective procedure with selective neck dissection, partial resection of the lower jaw and reconstructive procedure with a free osteomyocutaneous lower leg flap. The patient is being monitored with no signs of recurrence or subsequent metastatic spread of the tumor. Conclusion: This case emphasizes the importance of correct and timely diagnosis through various procedures and features of interdisciplinary cooperation of different specialists in the treatment of rare pathohistological diagnoses |
