Abstract:
Griscelli syndrome (GS) is a rare autosomal recessive immunodeficiency disorder in which the affected children present with characteristic silvery-white hairs. The hair microscopy of these children is characteristic and is helpful in differentiating GS from Chediak-Higashi syndrome which also presents with immunodeficiency and silver hairs. We report a 17-month-old boy with GS type 2 who presented with severe anemia. Bone marrow examination of the child suggested parvovirus B19 as the cause of severe anemia, which was later confirmed by DNA polymerase chain reaction.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
