Giant fibroadenoma of the breast in adolescents: report of 2 cases

Giant fibroadenoma (GF) is an uncommon variant of fibroadenomas that represent the most frequent breast lesion in adolescents and young women. The authors present 2 cases of GF of the breast in girls aged 12 and 14 years, and the respective diagnostic workup and conservative surgical treatment. Giant fibroadenomas are benign tumors, but their rapid growth and large size together with their rarity may determine difficulties in the clinical approach. Moreover, GF must be excised in all cases to exclude a phyllodes tumor and to prevent later deformity
