Aplastic crisis and leg ulceration: two rare complications of hereditary sideroblastic anaemia.

Aplastic crisis as a result of parvovirus infection is seen in a number of haematologic disorders characterized by decreased red cell survival, and leg ulceration due to unknown causes is seen in a number of haemolytic anaemias. Neither of the two has been reported in a case of sideroblastic anemia. We report one case with each of these complications in association with sideroblastic anaemia.

Acquired haemoglobin H disease in a case of myelodysplastic syndrome.

A case of acquired haemoglobin H (HbH) disease with underlying myelodysplastic syndrome in the form of acquired idiopathic sideroblastic anaemia is reported. Family studies and subsequent drop in HbH percentage strongly supported the acquired nature of the defect.
