Abstract: The patient, a 70-year-old woman, presented with a mass in the right nasal cavity accompanied by recurrent nosebleeds for 3 months. Physical examination revealed a mass in the right nasal vestibule, with a diameter of about 1.5 cm. The surface of the mass was not smooth and nasal CT showed a mass in the right nasal vestibule, which could be surgically removed. Immunohistochemical results of the tumor showed CKpan(3+), CK5/6(3+), p40(3+), p53(+), CD10(-), AR(-), Bcl-2(-), ki-67(+20%). Pathological diagnosis was acantholytic dyskeratotic acanthoma. This disease is rare and easy to be misdiagnosed, so it is necessary to pay attention to identification.
