Abstract

The metastatic spread of infraclavicular malignancies to the nasal cavity is rare. We describe the case of a 58-year-old man who presented with a 4-month history of right-sided rhinorrhoea, maxillary hypoesthesia, hyposmia and hypogeusia. Clinical examination revealed an irregular mass within the right nasal cavity. Immunohistochemical analyses of biopsies were consistent with small cell carcinoma of indeterminate origin. A positron emission tomography scan demonstrated extensive mediastinal lymphadenopathy with collapse-consolidation of the right lung's middle lobe and no other sites of metastasis. Following discussion at the lung multidisciplinary team meeting, a diagnosis of metastatic small cell lung cancer (SCLC) was made; the patient was staged with N3, M1b disease and palliative chemo-radiotherapy was started. To the best of our knowledge, this report represents the first documented case of a solitary nasal cavity metastasis arising from a SCLC.
