[Paget's disease of the breast in a male].

The case of a 78-year-old man with Paget's disease of the breast, described herein, appears to be only the 22nd histologically proven case of this rare condition; in over 100 years less than 50 cases have been reported. Since this patient had no underlying tumour or nodal involvement the operation consisted of total mastectomy with removal of axillary nodes only, rather than the classical radical mastectomy. All eczematoid lesions of the areola of the breast that persist for more than 2 weeks or are unilateral should be considered Paget's disease until proven otherwise by biopsy.
