Non-salivary diseases that might be misdiagnosed as parotid lesions due to their localization are reviewed. These are classified into lymphadenopathies including inflammation and metastasis, masseteric muscle lesions including benign hypertrophy and tumors, odontogenic lesions, and dermal lesions including inflammations and cysts and parapharyngeal tumors. Imaging such as CT, echography and CT sialography are indispensable for differential diagnosis. Benign masseteric hypertrophy and odontogenic periostal abscess are misleading to otolaryngologists, whereas metastasis from the head and neck regions is often misdiagnosed by others. The earlier and more appropriate the examination and treatment plans are established, the better results are obtained.
