Breast Sarcoidosis: An Unusual Manifestation

Abstract

Breast involvement in the context of systemic sarcoidosis is rare and may mimic a malignant lesion. Imaging studies contribute to the detection of breast lesions but are not useful in establishing a definitive diagnosis. Thus, malignancy must be excluded by histological biopsy in order to confirm the early diagnosis. We report a case of breast involvement by sarcoidosis in a 63-year-old woman with known systemic sarcoidosis. Mammography shows multiple oval nodular opacities with microlobulated edges and high density, without associated microcalcifications. Ultrasonographically, they corresponded to solid hypoechoic masses with microlobulated contours in both breasts, findings that were considered suspicious for malignancy. The breast Magnetic Resonance showed multiple bilateral nodules with endovenous contrast uptake. Histological examination confirmed breast involvement by sarcoidosis.
