Malignant tumors of the temporal bone are rare. They include a wide histological variety. They are mostly primary tumors with an estimated incidence of 0.8-1.0 per 1,000,000 inhabitants per year [1]. Metastases form an uncommon subgroup. The clinical features of these temporal bone metastases are nonspecific and predominantly consist of hearing loss, vertigo, facial palsy, tinnitus, headache, otalgia or otorrhoea [2]. The aim of our publication is to report a rare case of metastasis in the temporal bone as initial manifestation of lung cancer. Our patient was a 44-year-old man who presented for a right mastoid swelling with a grade VI right facial nerve palsy. Imaging and biopsy confirmed the diagnosis of small cell lung carcinoma petrous metastasis. The treatment was palliative. An osteolytic lesion of the temporal bone in an elderly patient may fit with a primary tumor of the temporal bone. It must, also, suggest the diagnosis of metastasis. The malignant tumor most frequently responsible is breast cancer, but lung cancer must also be considered in smoking patients.
