Women with complex fibroadenomas may therefore be managed with a conservative approach, similar to the approach now recommended for women with simple fibroadenomas. Because of their high mobility, they are also referred to as mouse in the breast/breast mouse. It is important to recognize the disease entity and characteristic cytomorphological findings of CFA to reach accurate FNA diagnosis of breast lesions.
