To the Editor:The Parotid Gland,out of all the salivary glands,is the one most frequently affected by neoplasms,accounting for approximately 75% in all cases.[1] These neoplasms are generally benign,with only 25% of them being malignant forms.[1] The percentage of distant metastases from salivary gland is relatively low,with their occurrence being associated with high-grade tumors.The Adenoid Cystic Carcinoma (ACC) is a tumor of exocrine glands originating primarily from the minor salivary glands of the upper respiratory gland,the major salivary glands,lacrimal gland,bronchus,breast,and intestinal and genital tracts.[2] Its key characteristic is that it grows slowly;however,peritumoral invasion and perineural infiltration occur in the process.To date,the spinal metastasis from ACC of the parotid gland is exceedingly rare in literature,with only a few cases presenting spinal metastasis of the parotid gland have been documented,thus resulting in consequence of lacking imaging proof.Herein,we described a case of spinal metastases ofparotid carcinoma treated with surgical treatment.
