Pseudoangiomatous stromal hyperplasia (PASH) of the breast is a benign mesenchymal
lesion with incidental histologic findings. Surgical excision is recommended as the
treatment of choice for PASH, although the recurrence rates after excision range from
15% to 22%. A 46-year-old-female presented with a six-month history of bilateral breast
enlargement and painful sensation mimicking inflammatory carcinoma. Imaging studies
demonstrated innumerable enhancing nodules in both breasts. Due to the growth of the
lesions and progressive clinical symptoms, bilateral subcutaneous mastectomy was performed.
Grossly, the specimens were round and well-circumscribed, and the histologic examination
revealed PASH. After mastectomy, we created a pocket with the pectoralis major muscle
and a lower skin flap, which was deepithelized. Anatomical mammary implants were inserted,
and the nipple areolar complex was transferred to a new position as a free graft.
The aesthetic result was satisfactory after twelve months of follow-up.
