Abstract

We report a case of mammary Paget disease with non-invasive ductal carcinoma (comedo carcinoma) . The patient was reconstructed by de-epithelized transverse rectus abdominis musculocutaneous flap successfully and cosmetically.
A 49-year-old female showed the erosion with slight itching on her left nipple. On the pathological study of a skin biopsy, mammary Paget disease was diagnosed. Furthermore, it was expected that the lesion progressed to the intraductal region on the findings of the graphical studies. After resection of left mammary gland with left nipple and areola, the tissue defect was successfully reconstructed by de-epithelized transverse rectus abdominis musculocutaneous flap. On the pathological studies postoperatively, the intra mammary lesion was diagnosed as non-invasive ductal carcinoma.
