Familial isolated congenital asplenia
Familial isolated congenital asplenia is a rare non-syndromic potentially life-threatening visceral malformation characterized by the absence of normal spleen function resulting in a primary immunodeficiency. Typically the condition manifests with severe recurrent overwhelming infections (especially pneumococcal sepsis) in otherwise apparently healthy infants. In adults with no history of severe sepsis in infancy thrombocytosis may be the presenting sign. Howell-Jolly bodies on blood smears and an absent spleen on abdominal ultrasound examination are highly suggestive associated findings.
