Osteopetrosis

Osteopetrosis is an inborn error of skeletal development and regulation of bone formation and resorption which results in generalized sclerosis and hardening of the bone. Because this process drives out the bone marrow, anaemia and extra-medullar haematopoiesis results, also splenomegaly.
