Abstract
Pleomorphic adenoma is a benign tumor and the most common salivary gland neoplasm. Metastasizing pleomorphic adenoma shares histological characteristics with pleomorphic adenoma but exhibits malignant behavior, including local lymph node involvement and/or distant metastasis. Several potential risk factors for metastasizing pleomorphic adenoma have been identified, some of which are associated with incomplete tumor clearance due to inadequate surgical techniques used in the treatment of primary pleomorphic adenoma. Here, we present a rare case of metastasizing pleomorphic adenoma originating from the parotid gland and describe its clinical features. The patient was a 75-year-old female with a surgical history of enucleation of a pleomorphic adenoma in the left parotid gland. Total parotidectomy and left neck dissection were performed for the left parotid tumor this time, and the patient attended one postoperative outpatient visit but subsequently was lost to follow-up.
期刊介绍：
SAGE Open Medical Case Reports (indexed in PubMed Central) is a peer reviewed, open access journal. It aims to provide a publication home for short case reports and case series, which often do not find a place in traditional primary research journals, but provide key insights into real medical cases that are essential for physicians, and may ultimately help to improve patient outcomes. SAGE Open Medical Case Reports does not limit content due to page budgets or thematic significance. Papers are subject to rigorous peer review and are selected on the basis of whether the research is sound and deserves publication. By virtue of not restricting papers to a narrow discipline, SAGE Open Medical Case Reports facilitates the discovery of the connections between papers, whether within or between disciplines. Case reports can span the full spectrum of medicine across the health sciences in the broadest sense, including: Allergy/Immunology Anaesthesia/Pain Cardiovascular Critical Care/ Emergency Medicine Dentistry Dermatology Diabetes/Endocrinology Epidemiology/Public Health Gastroenterology/Hepatology Geriatrics/Gerontology Haematology Infectious Diseases Mental Health/Psychiatry Nephrology Neurology Nursing Obstetrics/Gynaecology Oncology Ophthalmology Orthopaedics/Rehabilitation/Occupational Therapy Otolaryngology Palliative Medicine Pathology Pharmacoeconomics/health economics Pharmacoepidemiology/Drug safety Psychopharmacology Radiology Respiratory Medicine Rheumatology/ Clinical Immunology Sports Medicine Surgery Toxicology Urology Women''s Health.
