Pseudo Angiomatous Stromal Hyperplasia of the Breast: A Case of A 19-Year-Old Asian Girl

Abstract

Pseudo Angiomatous Stromal Hyperplasia (PASH), a benign disease with extremely low incidence, is manifested as giant breasts, frequent relapse after surgery, or endocrine disorder. Cases with unilateral breast and undetailed endocrine condition have been reported in African and American. In this case, a 19-year-old Asian girl suffered from bilateral breast PASH after the human placenta and progesterone treatment for 3-month delayed menstruation. Her breasts enlarged remarkably 1 month after the treatment, with extensive inflammatory swell in bilateral mammary glands and subcutaneous edema in retro mammary space. The patient received the bilateral quadrantectomy plus breast reduction and suspension surgery to terminate the progressive hyperplasia of breast. During the whole treatment period, the patient was given tamoxifen treatment for 4 months, and endocrine levels were intensively recorded. The follow-up after 4 months showed recovered breast with normal shape and size, and there was no distending pain, a tendency toward breast hyperplasia, or menstrual disorder. Level of Evidence: Level IV, case study. Keywords: Pseudo angiomatous stromal hyperplasia; 19-year-old Asian girl; Tamoxifen
