Multiple fibroadenomas with cystsarcoma phylloids in bilateral breasts of a 23- year-old Indian woman - A case report

Fibroadenomas are among the most common tumours of the female breast, occurring most frequently in women of child-bearing age, especially those under 30 years. We report a case with a total of 13 fibroadenomas presenting bilaterally of a 23-year-old woman. The histopathologic and immunophenotypic features of the fibroadenomata are described. Most fibroadenomas are present as single mass, however the presence of multiple fibroadenomata can be seen in 15-20% of the patients. It has been reported that the average number of masses in cases of multiple fibroadenomas is 3-4 in a single breast but occurrence of more than five fibroadenomas in an individual patient is much less common. There are few reports of multiple fibroadenomas. We report this case hoping to expand the literature and to provide insight to aetiology of multiple fibroadenoma formation and advice on management.
