The lump has been very painful and “changed” in color (Figure 80-1). Her mother is concerned about the size of the lump, having seen it only three days prior to her visit. The patient reached menarche at age 12 years and is not taking any medications. She has never been pregnant. The diagnosis of giant fibroadenoma was suspected and the girl is referred to a breast surgeon. Given the size of the lesion, and severe asymmetry, it was advised that she have an excision of this mass with reconstruction to achieve a better cosmetic result. She underwent surgical excision of the mass, which confirmed a giant fibroadenoma. After the procedure, her breasts appeared symmetrical and she healed very well.There is concern that her left reconstruction may need to be revised in the future as her other breast will mature appropriately for her age. This will need to be followed into adulthood.
