Giant pilomatricoma simulating carcinoma of the male breast

We present the case of a 65-year-old man with a targe calcifying epitheliom a in the right breast. The case is unusual not only for the size of the tum our 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 histolo gical evidence of malignancy or aggressive behaviour. One year after surger y there was no recurrence or metastatic disease. The possibility of maligna ncy, recurrence or metastasis of these large tumours, as well as the necess ity of follow-up and investigations, are emphasised.
