Abstract


Pleomorphic adenoma (mixed tumor) is most common in parotid followed by submandibular gland. It exhibits bimodal
population of cells with varied stroma. We report a case of 30 years old female presented with left submandibular gland swelling.
On examination, a 5x4 cms firm swelling which was ballotable on bidigital palpation was seen. Ultrasound showed well defined
hypoechoic vascularised lesion in the left submandibular triangle. FNAC showed features of pleomorphic adenoma. The lesion
was excised and post operative period was uneventful. Histopathology showed epithelial and myoepithelial cells distributed in a
chondromyxoid stroma without any vascular and capsular invasion. In conclusion mixed tumor of salivary glands should be
excised without any delay as the chances of malignant transformation to carcinoma ex pleomorphic adenoma was there.
