Giant fibroadenoma of the breast in late third trimester

Abstract

Giant fibroadenomas (GFs) occurring during pregnancy are extremely rare, and only a few cases have been reported. Although it is a benign condition, it often requires biopsy or even surgery to exclude malignancy. The authors report a new case of GF in a 29-year-old pregnant woman with a family history of breast cancer. She presented at 37 weeks of gestation with a large mass in her left breast. Tru-cut biopsy was suggestive of fibroadenoma. After delivery, enucleation of the mass was performed, and histology confirmed the previous diagnosis. Benign neoplasms should be suspected in any pregnant woman with a rapidly enlarging breast mass. Early surgical excision should be offered as a standard treatment to avoid structural damage to the breast and the need for reconstructive surgery.
