Malignant melanoma may metastasize to any anatomic site via the hematogenous route. A patient is described in whom a metastasis developed in the left maxillary antrum and nasal cavity and who received successful palliative surgical and radiotherapeutic treatment.

Metastatic carcinoma involving the paranasal sinuses has been reported most frequently secondary to renal cell tumors, followed by carcinoma of the lung and breast (Jortay, 1971; Robinson, 1973; Friedmann and Osborn, 1965; Bernstein et al., 1966). These tumor deposits are often diagnosed in a setting of diffuse metastatic disease or discovered at post-mortem examination. A patient recently treated at Pondville Hospital had symptomatic metastatic melanoma involving the left maxillary antrum and nasal cavity. Following surgical treat-ment, palliative radiotherapy was successfully delivered on three occasions providing symptomatic relief over the subsequent 17 months prior to the patient's death.
