Invasive Micropapillary Carcinoma in Breast Presented as Hyperechoic Mass with Coarse Macrocalcifications: A Case Report

ABSTRACT

Invasive micropapillary carcinoma is a rare, clinically aggressive variant of invasive ductal carcinoma. Imaging findings of invasive micropapillary carcinoma are not specific, and associated microcalcifications are frequent. Our case presented with unique radiological features a mass with coarse macrocalcifications on mammography and breast computed tomography and a hyperechoic mass on breast ultrasound. Macrocalcifications and hyperechogenicity are not usual malignant characteristics. We report here on our experience with a 55-year-old woman who had invasive micropapillary carcinoma in the breast with unique radiological and pathological findings.
