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.
多形性腺瘤（PA）是最常见的涎腺良性肿瘤，占所有此类肿瘤的80%。虽然PA最常发生于腮腺（85%的病例），但也可累及下颌下腺（8%）、舌腺和小涎腺。它是一种生长缓慢且持续的良性肿瘤，未经治疗可长得非常大。本文描述了1例发生于下颌下腺的巨大PA，经手术完整切除，无后遗症。在我们的病例中，1名男性患者有4年多的肿瘤病史，切除肿物重量为2.24 kg。下颌下腺的巨大PA在医学文献中非常罕见。
