Giant fibroadenoma in a 22 year old patient: case report and literature review.

Giant fibroadenomas are a rare form of fibroadenoma that present as rapidly enlarging breast masses. They are typically greater than 5 cm or 500 grams in size and most frequently are seen in premenopausal Afro-Caribbean or East Asian females. This unique case report presents a 22-year-old female who presented with an enlarging breast mass measuring 23 × 28 cm. After core needle biopsy, the mass was diagnosed as a giant fibroadenoma and treated surgically with mastectomy. After a 5 year follow up she has not reported any signs of recurrence of the mass.
