Giant presentation of pleomorphic adenoma in major salivary gland.

Pleomorphic adenoma (PA) is the most common benign salivary gland tumour, accounting for as many as 80% of all such tumours. Although PA most commonly occurs in the parotid gland (85% cases), it may involve submandibular (8%), lingual and minor salivary glands. It is a benign tumour with a slow and continuous growth and without treatment can assume enormous dimensions. This paper describes a giant PA's arising in the submandibular gland and treated by complete surgical excision without sequel. In our case, a male patient presented with a tumour history of more than 4 years and weight of the resected mass was 2.24 kg. Giant PA's of the submandibular gland are very rare in medical literature.
