Extramedullary plasmacytoma (EP) is a relatively rare neoplasm; about 90% of cases are localized in the head and neck area. EP has been considered a precursor of multiple myeloma but cases showing long disease free intervals or cure by surgery alone have been reported. A research of the world literature pointed out the extremely rare localization of solitary plasmacytoma in the salivary glands. Only 9 cases have been reported until now, 6 in the parotid gland, 2 in the submandibular glands and 1 in both the parotid and submandibular gland.
髓外浆细胞瘤（EP）是一种相对罕见的肿瘤；约90%的病例位于头颈部区域。EP曾被认为是多发性骨髓瘤的前驱病变，但也有报道称有些病例疾病无进展期较长或仅通过手术即可治愈。一项对世界文献的研究指出，孤立性浆细胞瘤在唾液腺中的定位极为罕见。截至目前，仅报道了9例，其中6例位于腮腺，2例位于下颌下腺，1例同时累及腮腺和下颌下腺。
