Giant fibroadenoma of the breast: A case report of a 37-year-old woman during the second trimester of pregnancy

Abstract

Fibroadenomas are the most common benign breast tumors in young women aged between 20-30 years. Giant fibroadenomas are often larger than 5 cm, weigh more than 500 g or occupy 80% of the breast. They can mimic malignant tumors because they grow rapidly and cause breast deformity. We present a young female patient, in the second trimester of her pregnancy, who had a rapidly growing giant fibroadenoma. Since the mass was suspected of malignancy and caused deformity in the breast, surgical excision was indicated. The operation was performed without complications and the patient was discharged on the second postoperative day. Although the second trimester is suitable for semielective surgeries that cannot be postponed, the timing of the operation is decided by a multidisciplinary team including surgeons, anesthesiologists, obstetricians and perinatologists.

“…The prevalence of fibroadenoma during the adolescent period is 2.2% and 1-8% of fibroadenomas are giant juvenile fibroadenomas [8,9]. "Giant" fibroadenomas are called fibroadenomas larger than 5cm or heavier than 500grams or when the mass is greater than 80% of the normal breast size [4]. In our case, fibroadenoma was complex, larger than 5 cm (22cm) and its weight was heavier than 500 g (1600 g).…”

“…It is defined as "giant" when the fibroadenoma is larger than 5cm, weighs more than 500 g or occupies for at least 80% of breast volume. Giant fibroadenoma of the breast usually occurs in patients younger than 20 years of age [4,5]. Fibroadenomas are ought to be benign lesions but they have tendency to grow faster.…”
