Sarcoid-Like Reactions in Breast Cancer Patients: A Report of Two Cases.

Sarcoid-like reactions (SLR) in patients with malignancies are a relatively common finding. Defined by the presence of non-caseating granulomas, SLR does not meet the clinical criteria for classic sarcoidosis. In cancer patients, SLR often presents a challenging differential diagnosis, as it must be distinguished from disease progression due to malignancy. We present two cases of SLRs associated with breast cancer, underscoring the need for heightened vigilance among physicians. SLR should always be considered a potential diagnosis in these patients, with histological confirmation being essential for accurate identification.
