Sonographic and Magnetic Resonance Imaging Characteristics of Juvenile Papillomatosis: Three Cases With Different Manifestations.

Juvenile papillomatosis (JP) is an infrequently seen benign proliferative lesion in women younger than 30 years. Herein, we present different clinical manifestations of histopathologically proven JP of the breast, in addition to magnetic resonance and sonographic imaging features of these cases. Patient 1 exhibited nipple discharge and papillary carcinoma accompanied after the operation. Patient 2 presented with a giant mass with cystic and numerous solid nodular components that filled the entire right breast. Patient 3 exhibited cystic areas in a well-circumscribed hypoechoic solid mass besides ahypoechoic mass with indistinct borders, which was evaluated as multifocal JP.
