Adenoma of ceruminous glands has rarely been reported. The first such report was made by Haug1 in 1894. He called an adenoma acinosum of sebaceous glands a tumor akin to adenoma of ceruminous glands. The tumor was in a man 35 years old in whom the only abnormal finding was a growth in the entrance of the external auditory canal. Microscopic examination revealed a tumor composed of glandular alveoli with fibrous septums showing (1) alveoli lined with epithelial cells which were larger at the periphery and smaller toward the lumen and (2) vacuolated alveoli lined with a double row of epithelial cells. This second pattern he regarded as an abnormal pattern of sebaceous gland structure. Haug described a second case as one of "adenocarcinoma of the aural sweat glands with myxomatous degeneration of the stroma" in a man whose only abnormality was an ulcerated nodule of the external auditory meatus
