The simultaneous occurrence of benign and malignant tumours in the ipsilateral parotid gland is extremely rare. The cases of five patients with synchronous multiple parotid gland tumours consisting of diverse combinations of benign and malignant histological types are presented here. In addition, all published cases of this entity identified in the PubMed, Embase, and Web of Science databases up to January 2018 were reviewed. It is concluded that clinical vigilance should be raised when multifocal tumours are indicated by imaging examinations, in the presence of unmovable, painful, and rapid growth or symptoms of facial nerve palsy. In such cases, resected specimens should be sectioned meticulously, especially for tiny lesions, during histopathological sampling. Based on the possibility of the co-existence of benign and malignant neoplasms, it is necessary for clinicians to pay attention to this entity in order to have a favourable outcome.

D010808	Physical Examination	Systematic and thorough inspection of the patient for physical signs of disease or abnormality.	Physical Exam,Examination, Physical,Physical Examinations and Diagnoses,Exam, Physical,Examinations, Physical,Exams, Physical,Physical Examinations,Physical Exams
D005158	Facial Paralysis	Severe or complete loss of facial muscle motor function. This condition may result from central or peripheral lesions. Damage to CNS motor pathways from the cerebral cortex to the facial nuclei in the pons leads to facial weakness that generally spares the forehead muscles. FACIAL NERVE DISEASES generally results in generalized hemifacial weakness. NEUROMUSCULAR JUNCTION DISEASES and MUSCULAR DISEASES may also cause facial paralysis or paresis.

D012189	Retrospective Studies	Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
