“…To the best of our knowledge, only one case of spinal metastasis that was reported as the first clinical sign of parotid ACC has been presented in the literature [ 4 ]. Their patient (a 68-year-old female), like our two patients, was successfully managed by surgical procedure but radiation therapy was not performed [ 4 ]. Researchers have suggested the posterior approach for spinal decompression when the spinal metastases have caused neurological symptoms, especially myelopathy and radiculopathy [ 4 ].…”

“…Researchers have suggested the posterior approach for spinal decompression when the spinal metastases have caused neurological symptoms, especially myelopathy and radiculopathy [ 4 ]. They recommended radiation therapy in incomplete excision cases or residual disease [ 4 ]. Due to microscopic involvement in the resected margins, we recommend radiation therapy after spine surgery even with grossly resected lesions.…”

“…The tumor is usually slow growing compared with other carcinomas, and the frequent sites of metastasis are lungs, bone, liver, and, rarely, the brain [3]. Spinal metastasis from ACC of the salivary glands is an exceedingly rare situation, and only a few case reports exist in the literature [3][4][5]. Here, we present two rare cases of spinal metastasis from ACC of the parotid gland.…”

Background Spinal metastasis from adenoid cystic carcinoma of the salivary gland is extremely rare. We present two interesting cases of spinal metastasis from adenoid cystic carcinoma of the parotid gland. Case summary A 29-year-old Persian male and a 48-year-old Persian female presented with parotid gland mass. The two patients received parotidectomy and radiotherapy. The pathological examination result was adenoid cystic carcinoma. Because of intractable back pain, patients were referred to the hospital after 7 years and 9 months, respectively. Both cases underwent spinal surgery. Histopathology confirmed spinal metastasis from adenoid cystic carcinoma of the parotid gland (case 1: T6, T12, and L1; case 2: T12). Anterior corpectomy of T12 and lateral screw fixation at T11 and L1 were done in case 2. Posterior spinal fusions from T2 to L3 and from T10 to L2 were performed in case 1 and case 2, respectively. Both patients showed good clinical improvement. The last follow-up (case 1: 24 months; case 2: 6 months after surgery), plain radiographs and computed tomography scan showed good fusion without instrumental failure and magnetic resonance imaging revealed good decompression of the spinal cord of both cases. Conclusion Although spinal metastasis from adenoid cystic carcinoma of the parotid gland is extremely rare, it is necessary to be careful in the differential diagnosis.
