Capecitabine-induced sarcoidosis in an oncology patient: Clinical presentation with arthritis.

Sarcoidosis is a multisystemic granulomatous disease of uncertain etiology. Several drugs have been linked to the development of sarcoidosis or systemic granulomatous reactions indistinguishable from this disease. We present the clinical case of a patient diagnosed with breast cancer and undergoing treatment with capecitabine who, after developing systemic and musculoskeletal symptoms, was ultimately diagnosed with capecitabine-induced sarcoidosis.
