Bilateral Lobular Invasive Carcinoma

case report

Abstract

Invasive Lobular Carcinoma (CLI) is a malignant disease and it was described in 1946 by Foote and Stewart. It is the second histological type of breast cancer representing 5–10% of all carcinomas. It is histopathologically characterized as an invasive lobular intraepithelial neoplasia, with the presence of small and uniform cells. We report the case of 61 year old that after 6 months of monitoring, her mammography study showed an architectural distortion in the Upper External (QSE) of right breast corresponding to textural changes associated with posterior acoustic shadow evident on ultrasonography (USG), spiculated and ill-defined nodule in the left breast QSE, BI -Rads 4c. A fine needle (FNA) puncture in the ME report with grouping of small and atypical epithelial cells with the carcinoma hypothesis most likely to be held. The patient underwent bilateral segmentectomy and sentinel lymph node of left breast. The Histopathology Report showed CLI lymph node of the left breast free of neoplasia. The histopathological and clinical characteristics of the CLI are the imaging features of the lesions are of variable appearance. Therefore, the correlation between the different imaging modalities help to determine the extent and number of injuries.
