Delayed Diagnosis of Metastatic Prostatic Adenocarcinoma in Temporal Bone / 대한이비인후과학회지

ABSTRACT

Metastasis to the temporal bone is uncommon. In some cases, metastasis may be the first evidence of malignant dissemination, but more frequently, the diagnosis is unsuspected, possibly because ear symptoms are overshadowed by those deriving from the primary tumor. It is not until they have symptoms like hearing loss, otalgia, facial nerve paralysis, periauricular swelling, otorrhea, or even an aural mass that patients usually undergo treatment at the late stage of the disease course. Tumors of the breast, lung, and kidney are the most common sources of temporal bone metastasis. Although axial bone and cranial metastases are common in patients with prostatic carcinoma, temporal bone involvement is extremely rare. We report a case of metastatic prostatic adenocarcinoma in the temporal bone which was diagnosed with delay.
