We presented a case of axillary Paget's disease. The patient was a 75-year-old man who noticed on his left axillary area a round shaped erythema of 2 centimeters in diameter. In 2 months, he had an itch and he consulted us. By punch biopsy, we diagnosed Paget's disease as carcinoma in situ. But, histological examination of excision specimen showed microinvasion of Paget's cells in dermis.
In extra-mammary Paget's disease, axillary Paget's disease is rare compared with external genital Paget's disease. About microinvasion in dermis, in axillary Paget's disease it is more frequent than in external genital Paget's disease. In the case of single axillary Paget's disease as well as extermal genital Paget's disease, we have to treat it as cancer.
