Among the tumours of the major and minor salivary glands there is a group that is characterized by the participation of two cellular components, the epithelium and the lymphoid tissue. Lymphatic tissues may be seen within or closely associated with oral mucosa in a variety of anatomic & pathologic conditions.  Lymphoepithelial lesions are a group of lesions which share in common the dual participation of the epithelial tissue & the lymphoid tissue. The majority of these lesions involve the salivary gland & the neck region. In this paper the author has reviewed the main etiological and pathological features of these lesions and tried to classify the lesions in different groups according to their etiology, gross pathological and histological features and prognosis by reviewing different articles in literature.
