Abstract
BackgroundInvasive Papillary Carcinomas (IPC) are rare and account for approximately 0.5% of all invasive breast carcinomas. Most of them are seen in post-menopausal women and have a good prognosis. These tumors lack the myoepithelial cell layer (MCL) within the papillae or at the periphery of the tumor with areas showing stromal invasion or invasion into lymphovascular spaces. Immunohistochemistry (IHC) for myoepithelial cells and basement membrane is essential for the diagnosis of invasive cancer.Case presentationWe present a rare case of IPC in a 74-year-old woman who presented with complaints of gradually increasing painless retroaerolar mass in the left breast of two months duration. The mass was irregular, having an oblong as well an adjacent high density mass lesion on mammography. Ultrasound (US), and Magnetic Resonance Imaging (MRI) helped in the diagnosis of the possibility of a malignant breast lesion. Left-sided modified radical mastectomy was performed and the specimen was histopathologically diagnosed as Invasive Papillary carcinoma. Immunohistochemistry confirmed the diagnosis.ConclusionsInvasive Papillary Carcinomas of the breast are rare cancers in post-menopausal women. We have highlighted the role of Mammography, US, and MRI in early diagnosis so that timely management is possible.
Highlights
We have highlighted the role of Mammography, US, and Magnetic Resonance Imaging (MRI) in early diagnosis so that timely management is possible
Ultrasound and MRI can help in making a diagnosis of Invasive Papillary Carcinoma of the breast
We would like to emphasize on the rare presentation of this Invasive Papillary Carcinoma as an Intraductal mass filling the dilated duct along with extension outside the duct as a solid mass lesion
Summary
We would like to emphasize on the rare presentation of this Invasive Papillary Carcinoma as an Intraductal mass filling the dilated duct along with extension outside the duct as a solid mass lesion.
