Atrophy of the tongue as the presenting feature of metastatic prostate cancer.

Prostate cancer is the most frequently diagnosed solid organ cancer in men and is the second leading cause of cancer-related deaths in men in the United Kingdom. Commonly, it metastasizes to bones and lymph nodes, however, in advanced hormonerefractory disease it may involve the skull base leading to associated cranial nerve palsies. Cranial nerve palsy as the presenting feature of advanced hormone-sensitive prostate cancer is extremely rare. To the best of our knowledge, we report the first case of solitary hypoglossal nerve palsy as the presenting feature of advanced prostate cancer. Neurologists, neurosurgeons and otolaryngologists may be the first clinicians to see such a patient; therefore, prostate cancer should be amongst the differential diagnoses considered in middle-aged and elderly men presenting with a cranial neuropathy and evidence of skull metastasis.
