Rare Form of Breast Cancer and Lung Foci: Do We Always Have to Wait for Metastases?

Abstract

Will the detected lung foci in patients with a burdened oncological history (breast cancer) always be metastatic? In response to the question posed, we present a clinical case of pulmonary sarcoidosis mimicking the metastatic lesion of metaplastic breast cancer. And we remind of the need for a differential diagnosis, despite the oncological history of a patient and radiation diagnostics data.
