abstract: A 47-year-old woman presented with a nodular lesion in the left retroauricular area. The lesion was enucleated and a diagnosis of malignant pilomatricoma was made. This was treated by wide excision and no residual tumour was found. The patient remained disease-free at the 18 months follow-up.
