Cyclosporin A-induced fibroadenomas of the breast: Report of five cases

Five female patients undergoing cyclosporin A therapy had newly developed b reast masses. Masses were bilateral in three of the five patients and palpa ble in four patients. The imaging findings were suggestive of fibroadenomas , and biopsy results were used to confirm the diagnosis. With the developme nt of new breast lesions in patients after transplantation surgery, the dia gnosis of cyclosporin A-induced fibroadenomas should be considered.
