Pseudoangiomatous stromal hyperplasia (PASH) is a rare benign breast lesion, which commonly affects premenopausal women. It occurs as a single node, which is mobile, firm and usually unilateral. PASH is characterized by a benign overgrowth of fibrous connective tissue of the breast, which produces numerous spaces resembling vascular structures. The diagnostic alternative is currently provided by the ultrasound guided percutaneous biopsy or stereotactic biopsy, which determines the nature of the lesion and rules out malignancy, such as angiosarcoma, in order to avoid unnecessary surgical biopsies. We present two lesions that were classified as BI-RADS 4c in the initial control by mammography, which led to a needle biopsy.
