A case of castration-resistant prostate cancer metastasis to an external auditory canal is described. Prostate cancer (cT3aN1M1b GS5+5) was discovered in a 68-year-old man. Despite the fact that abiraterone, docetaxel, and cabazitaxel were administered and PSA levels were reduced, liver metastasis developed [1-15].Hearing loss was also noted in the left ear, and the patient was referred to an otolaryngologist for an examination, which revealed a neoplastic lesion in the external auditory canal. The results of the biopsy revealed that the patient had adenocarcinoma. Details of a rare case of prostate cancer metastasis to an external auditory canal are presented here.
