The authors present the case of a 47 year old woman with a history of a primary breast cancer and local recurrence, who developed disseminated pulmonary lesions, supra- and infra-diaphragmatic adenopathies and a lytic lesion of the right iliac bone nine years later. The diagnosis of disseminated carcinomatosis was initially suspected but a targeted bone biopsy surprisingly revealed the presence of sarcoidosis typical lesions. In this case, none of the sophisticated imaging tools could provide an accurate differential diagnosis. Thus for such cases, an anatomo-pathological analysis is definitively mandatory in order to avoid overtreating patients without evolutive cancer.
