INVASIVE MICROPAPILLARY BREAST CARCINOMA DISCOVERED DURING THE INVESTIGATION OF ACUTE RESPIRATORY DISTRESS IN A POSTPARTUM WOMAN: A CASE REPORT

Invasive micropapillary carcinoma of the breast is a rare histological entity among breast cancers, representing 2 to 3% of breast carcinomas. Its clinical and radiological presentation is similar to other carcinoma entities. Diagnosis is primarily histological but remains challenging and dependent on the operator. It is an aggressive tumor with both local and distant extension (lymphatic, cutaneous, etc.). In this study, we present a case of invasive micropapillary carcinoma of the breast discovered during acute respiratory distress due to serous extension (pleural effusion). Through this case, we will discuss the various clinical, radiological, therapeutic, and particularly histological aspects of this rare type of carcinoma.
