A Case of Spontaneous External Auditory Canal Cholesteatoma

External auditory canal cholesteatoma (EACC) is a disease that is characterized by desquamating tissue and bone erosion. EACC is a disease with a postoperative or post-traumatic etiology, secondary to stenosis of the external auditory canal or, very rarely idiopathic (spontaneous or primary). Clinically, Primary external auditory canal cholesteatoma presents with nonspecific symptoms but many patients can be silent or even asymptomatic.
