Abstract
Bone marrow involvement in sarcoidosis is rare and poorly understood. This case highlights the hematologic complexity of sarcoidosis, including its association with aplastic anemia and T-cell large granular lymphocytic leukemia (T-LGLL). We report a 70-year-old male with longstanding sarcoidosis who developed multiple hematologic complications, including bone marrow granulomatous infiltration, aplastic anemia, and T-LGLL.
