A 61‐year‐old female presented with a longstanding parotid mass with recent change in size. Histologically, the mass was composed of extensively necrotic tissue with a peripheral rim of ribbons of epithelium. In one focus, a double layer of oxyphilic epithelium overlying a lymphoid stroma in a papillary configuration was present, establishing the diagnosis of adenolymphoma (AL). The possibility of infarction and/or infection complicating AL is discussed. In any parotid gland lesion clinically presenting as a longstanding tumor with recent change clinically suggestive of infarction and/or infection, the diagnosis of AL should be considered. In the pathologic specimen with extensive necrosis, areas of preserved epithelium and stroma should be searched for carefully to confirm the diagnosis. ACTA PATHOL. JPN. 34 : 1469–1474, 1984.
