Unusual presentation and inconclusive biopsy render fibroadenoma in two young females a diagnostic dilemma
Two young, nonlactating, nulliparous women presented with acutely painful breast masses. Sonographic features showed mixed echogenic masses. Core biopsies were not diagnostic, and surgical excision revealed infarcted fibroadenomas in both cases. Although fibroadenomas are common, they do not commonly infarct, and only rarely in non-lactating or non-pregnant females. These two cases highlight the clinical and imaging characteristics of an important differential diagnosis.
