Final answer:
Sarcoidosis can cause splenomegaly, anemia, and leukocytosis.
Step-by-step explanation:
Sarcoidosis is a disease characterized by the formation of granulomas, which are clumps of immune cells, in different parts of the body, including the spleen. The spleen can become enlarged, leading to a condition called splenomegaly (option A). In terms of hematological features, sarcoidosis can cause various blood abnormalities. These can include a decrease in red blood cell count, leading to anemia (option C), and an increase in white blood cell count, resulting in leukocytosis (option D). Thrombocytosis (option B), which is an increase in platelet count, is not typically associated with sarcoidosis.
