Simultaneous leukaemic infiltrate and cholesteatoma in the same temporal bone

Abstract Leukaemic relapse in the ear is very rare. We report a case of relapse of acute lymphoblastic leukaemia in the left ear. The patient presented with an aural polyp and ipsilateral facial palsy. The temporal bone showed simultaneous leukaemic infiltrate and cholesteatoma. To our knowledge, this is the first case reported with such pathology.
