Giant pilomatricoma simulating carcinoma of the male breast.

We present the case of a 65-year-old man with a large calcifying epithelioma in the right breast. The case is unusual not only for the size of the tumour but also for its location in a male breast. Despite its large size (12 x 10 x 7 cm), the tumour did not show any clinical, radiological or histological evidence of malignancy or aggressive behaviour. One year after surgery there was no recurrence or metastatic disease. The possibility of malignancy, recurrence or metastasis of these large tumours, as well as the necessity of follow-up and investigations, are emphasised.
