Spontaneous regression of Merkel cell carcinoma of the skin.
We report a 65-year-old man who presented with a Merkel cell carcinoma on his right ear, a small satellite nodule and regional lymph node metastases. No treatment was given because of his generally poor state of health. Spontaneous regression of all the lesions was observed within a month. Merkel cell carcinoma is a potentially aggressive tumour. Only four cases of spontaneous regression have been reported previously.
