Radiotherapy and hyperthermia in the treatment of primary Merkel cell carcinoma of the skin: a case report.

We report a case of a large Merkel cell skin tumor (left cheek) in an 83 year-old woman treated by a combination of radiotherapy and hyperthermia. A complete response to the treatment was observed and without side effects. The patient has now been followed for 12 months without signs of recurrence, nodal disease, or distant metastasis.
