Abstract: Tumours of the
salivary gland comprise of a small percentage of all head and neck tumours, of
which nearly 80% are benign. The submandibular gland tumours constitute only
5-10% of this group, of which pleomorphic adenoma is the commonest type. We
report a case of a large pleomorphic adenoma of submandibular salivary gland,
presenting as a neck swelling. A 65 years old female presented with complaints
of swelling over the front and right side of neck since 15 years. A MRI of neck
revealed Evidence of a well-defined large T2 heterogenous nodular lesion is
seen involving right side of neck from floor of mouth to supra-clavicular
level, crossing midline to the left side and showing heterogeneous enhancement
on post contrast study. It was seen to be involving adjacent skin. It showed
few blooming area with in suggest calcification with in. It was causing
significant mass effect inform of compression over right sternocleidomastoid
muscle, trachea, right thyroid - submandibular gland and right IJV with
maintained fat planes and left sided tracheal deviation. FNAC was suggestive of
salivary gland neoplasm with a possibility of pleomorphic adenoma with moderate
cytological atypia.
