Malignant salivary gland tumor usually involves the parotid gland. Although unusual locations have been reported for such tumors, we here report an extremely rare case of nasal location in a salivary gland adenoma with malignant transformation.
A 65-year-old man with diabetes and hypertension presented with left nasosinal tumefaction causing nasal obstruction with slow evolution and recent onset of epistaxis and slight telecanthus. CT, MRI and nasosinal bone biopsy were performed. Treatment was by surgical exeresis on an external approach.
Malignant transformation of a pleomorphic adenoma with nasal location is extremely rare and little described in the literature. Imaging found strong signs of malignancy, confirmed on histology. Surgical exeresis was the only effective treatment option.
恶性涎腺肿瘤通常累及腮腺。虽然已有报道称这些肿瘤发生在不常见的部位，但我们在此报告一例极为罕见的涎腺腺瘤恶性转化为鼻腔部位的病例。
一名 65 岁男性，患有糖尿病和高血压，出现左侧鼻旁肿胀，导致鼻阻塞，缓慢进展，近期出现鼻出血和轻微内眦距离增宽。进行了 CT、MRI 和鼻旁骨活检。治疗方法是采用外部入路进行手术切除。
发生在鼻腔部位的多形性腺瘤的恶性转化极为罕见，文献中描述较少。影像学检查发现有强烈的恶性征象，组织学检查得到证实。手术切除是唯一有效的治疗选择。
