Abstract:
We report an extremely rare case with a total of 50 fibroadenomas simultaneously presented in bilateral breasts and left axillary accessory breast, up to 8 cm in size, in a 20 year-old Chinese woman. The histopathologic and immunophenotypic features of the fibroadenomas are described and possible underlying pathogenesis is discussed. To our knowledge, this is the first case with such a large number of bilateral multiple breast fibroadenomas in a young female reported in the literature.
