Background: Cutaneous neuroendocrine neoplasms are typically malignant. Benign cutaneous neuroendocrine tumors are uncommon. Methods: We report the case of a 32-year-old female who presented with a granular mass in the right external auditory canal. Results: Microscopic examination of a shave biopsy revealed a poorly circumscribed neoplasm with glandular differentiation. While cytologic atypia and mitotic activity were not evident, pagetoid spread was observed. Immunohistochemistry was indicative of neuroendocrine origin. Conclusions: This case report of neuroendocrine adenoma indicates that this entity should be entertained in the repertoire of conditions affecting the external ear.
