Abstract
Abstract
This case study demonstrates a 48-year-old, white, premenopausal female with a palpable, painless lump in her right breast who came in for a regularly scheduled mammogram. The mammogram came back abnormal, and the patient was referred to ultrasound. The ultrasound visualized a small, round, well-circumscribed hypoechoic mass in the middle-upper quadrant of the breast, correlating to the location of palpation. The mass was suspected to be a fibroadenoma, however the patient was scheduled for a biopsy in order to confirm this. The biopsy results instead indicated pseudoangiomatous stromal hyperplasia (PASH). PASH is a benign proliferative lesion of stromal tissue found within the breast, typically in women who are premenopausal. It is believed to be influenced by hormones and is often asymptomatic. It has been known to have a significant recurrence rate when surgically removed. This case study demonstrates that not all well-circumscribed hypoechoic masses are fibroepithelial lesions and aims to address why differentiating between PASH and a fibroadenoma can be important for treatment in some cases.
