Breast hamartomas: a hidden diagnosis

Breast hamartomas are rare and poorly defined tumors made of glandular, adipose and fibrous tissue. We present two cases of breast hamartomas diagnosed within one year. Mammograms performed for both patients were not suggestive of a breast hamartoma and a prospective diagnosis could only be obtained through MRI in one patient. Both diagnoses were confirmed by histopathology. Despite the increasing incidence of breast hamartomas as a result of increased screening, the diagnosis of breast hamartoma may be missed due to the variability in its mammographic and histopathological findings
