To the Editor:
Girard et al. recently reported the association ofAdamsOliver syndrome and hepatoportal sclerosisin two unrelated children [Girard et al., 2005]. Theauthors raise the question of whether this associationis fortuitous or due to common vascular thromboticmechanism. We report on the same association ofboth disorders in an additional case.
A male of French origin was the first child born tonon-consanguineous healthy parents. Family historywas unremarkable. He was born at 41 weeks ofgestation with a birth weight of 2,800 g and did notreceive a venous umbilical catheter. Aplasia cutiscongenital, limb defects (syndactyly of left toes twoand three, absence of middle phalanx of left toes twoand five and right toe five, hypoplasia of distalphalanx of each left toe), and cutis marmorata werenoted at birth. Chromosome analysis showed anormal 46,XY karyotype.
At 3 years of age, he underwent plastic surgeryfor aplasia cutis repair and a thrombocytopenia(70 109/ml) was noted pre-operatively. At examina-tion splenomegaly was also noted but there was noliver enlargement and liver function tests werenormal. Prothrombin time was 70% (normal >65%)and factor V 61% (normal>65%). Portal hypertensionwas suspected. Endoscopyof theupper digestive tractfound Grade II esophageal varices. AbdominalDoppler echography and tomodensitometry withinjection neither show any obstruction of hepaticportal vein nor left and right portal intrahepatic vein.Percutaneous liver biopsy showed histological pat-
terns consistent with the diagnosis of hepatoportalsclerosis: portal fibrosis, loss of intrahepatic portalveins with dilated neocapillaries, and neoveinulesin place of host veins. No nodular regenerationwas observed. Other causes of cirrhosis andportal hypertension were excluded. Thrombophiliatesting included factor V Leiden, prothrombin 20210Amutation, methylene tetrahydrofolate reductase defi-ciency, anticardiolipin antibodies, antithrombin defi-ciency, protein S deficiency, and protein C deficiencywas negative. A 1-year follow-up showed increasingesophageal varices Grade III.
Until now only three cases of the association ofAdamsOliver syndrome and hepatoportal sclerosishave been reported [Swartz et al., 1999; Girard et al.,2005]. The pathological mechanism of hepatoportalsclerosis remains unclear. Girard et al. propose thatvasculopathy and thrombosis, possibly favored by agenetic pre-disposition, could lead to different typesof lesions and to the association of AdamsOliversyndrome and hepatoportal sclerosis. Girard et al.reported decreased activity of anticoagulant proteinsin their two cases. Pre-disposing factor of thrombosis

was not identified in our case. Unlike the twocases reported by Girard et al., the girl described bySwartz et al. and our child presented a pure case ofhepatoportal sclerosis since no obstruction of any ofthe portal veins was found.
This additional case reinforces the hypothesis thatAdamsOliver syndrome and hepatoportal sclerosisshare a vascular thrombotic mechanism and that thisassociation is not fortuitous. Careful clinical exam-ination and liver ultrasonography should be per-formed for patients with AdamsOliver syndrome to
detect portal hypertension that could appear duringthe first years of life.
