1.1. Background: Polymorphous adenocarcinoma is the second most common intraoral minor salivary gland tumor accounting for 26% of all carcinoma. It is characterized by varied architectural patterns with uniform cytologic picture.

1.2. Methods: We present a case of 45-year-old male who presented with a palatal swelling. neoplastic glandular epithelial cells showing variety of growth patterns and characteristic indian file pattern was also seen. Micro calcifications were also appreciated.

1.3. Results: All these features are suggestive of Polymorphous Adenocarcinoma (PAC). The patient received postoperative radiotherapy in view of close margins for a total dose of 50.4 Gy in 28 fractions. The patient is doing well 33 months post surgery without any clinical or radiological evidence of recurrence.

1.4. Conclusions: Palatal salivary gland malignancies pose a diagnostic dilemma for the pathologists. Any general practitioner should be skeptical about the palatal swelling and refer the patient to a specialist.
