We report a case of pleomorphic adenoma in the retromolar region. The lesion was initiallydiagnosed as a malignant neoplasm on the basis of clinical features and biopsy findings.
The patient was a 70-year-old man whose chief complaint was swelling of the left retromolar region.
Examination at presentation revealed a tumor measuring 25×15mm accompanied by an ulcer.
The lesion was identified as squamous cell carcinoma on examination of a biopsy specimen at another hospital. However, a biopsy done before surgery revealed mucoepidermoid carcinoma.
With the patient under general anesthesia, the tumor was resected with the submaxillary lymph nodes.
The final histopathological diagnosis was pleomorphic adenoma.
The tumor apparently originated from the molar glands.
