A case of pleomorphic adenoma of submandibular gland

Abstract

Pleomorphic adenoma is the most common salivary gland tumor. It possesses epithelial and myoepithelial elements with mucoid, myxoid, or chondroid tissue in a mucopolysaccharide stroma. Pleomorphic adenoma of submandibular gland is generally seen in middle aged women. It presents as a solitary, well defined, painless slowly growing benign tumor but can turn malignant. USG, FNAC and CT scan help in establishing diagnosis, extent and tumor’s relation with surrounding structures. Surgical excision is treatment of choice because of chances of malignant transformation.Our case was a young male who presented with right sided upper neck swelling for four months. It was painless, progressive and without any pressure symptoms. On examination, a 3 x 2 cm, globular swelling was seen in the right submandibular region. It was firm, non tender, mobile and ballotable on bidigital palpation. USG neck revealed a 2.1 x 2.7 x 3.1 cm well defined hypoechoic lesion in right submandibular gland. FNAC reported a pleomorphic adenoma.Gland was excised under general anaesthesia. Skin incision was given 2 cm below right mandible. Subplatysmal flaps were raised. Gland was excised in totality with precise dissection, preserving marginal mandibular nerve. Histopathological examination reported a final diagnosis of Pleomorphic Adenoma of right submandibular gland.
