Paediatric pleomorphic adenoma of sub mandibular gland – a uncommon occurrence

Abstract

Salivary glands tumours are rare, representing a wide variety of benign and malignant histologic subtypes, consisting of a group of heterogeneous lesions with complex clinico-pathological characteristics and distinct biological behaviours. Among salivary gland tumours incidence of pleomorphic adenoma in submandibular gland is 5-10% of the cases. We report a case of 13 year oldmale patient who presented with a swelling in left submandibular region since 3 months. On clinical examination he was found to have a 3x3cm solitary non tender firm swelling palpable in left submandibular triangle. Remaining ENT examination clinically unremarkable. Ultrasonography of neck showed Hetero echoic lesion of about 3.0x3.5cm size in left submandibular gland with mild increased vascularity. Similar findings were noted in computed tomography of neck. Fine needle aspiration cytology of swelling showed features suggestive of Pleomorphic adenoma of submandibular gland. Patient underwent excision along with submandibular gland under general anaesthesia and post operative period procedure was uneventful. Histopathology of excised specimen was consistent with pleomorphic adenoma. Patient is on regular follow up with no post operative complications.
