Benign salivary gland tumour with lymphoid tissue covered by epithelium. Found almost exclusively in the parotid glands, which occurs bilaterally, and is more common in men than in women. Typically, it is an encapsulated, smooth, round lesion with multiple communicating cysts. It has two components, lymphoid and epithelial, with two layers of cells; the surface row consists of tall columnar cells, and the deep row contains cuboidal, rounded, or polygonal calls.
