Abstract:
We describe a case of extramammary Paget's disease (EMPD) in the lateral part of the breast of a woman with known psoriasis. The eczema was treated as psoriasis for three years. There were no macroscopic changes of the nipple or areola. Nodular swellings beneath the eczema proved to be infiltrating ductal carcinoma. The eczema showed the pattern of EMPD. A mastectomy was performed. Two foci of ductal carcinoma in situ were found in the mammary body and two foci of Paget's disease were found in the areola and nipple. Fourteen axillary lymph nodes were examined without signs of malignancy.
