Mammary Paget's disease in a young woman: A rare occurrence

Mammary Paget's disease (MPD) is a rare intraepithelial carcinoma involving the nipple-areolar complex, often linked to underlying ductal carcinoma. We report a case of a 47-year-old woman presenting with progressive swelling of the left nipple, without pain, discharge, or inflammatory signs. Imaging revealed ductal dilation and nipple thickening, classified as BI-RADS 4, with MRI confirming additional suspicious findings. Histopathological analysis of a biopsy confirmed MPD associated with underlying ductal carcinoma in situ. This case underscores the importance of multimodal imaging and histopathology in diagnosing and managing this uncommon breast malignancy.
