Hemangioma is the most common liver benign tumor, however the associated with an adult KASABACH-MERRITT syndrome is rare; to date there is no multi case report or literatures reviews are available, in the last 30 years only 17 cases have been described in the literature.  we report in this work the case of a patient with a giant liver hemangioma associated to a KARABACH-MERRITT syndrome for which an ALPPS procedure have been realized.

The associated of Kasabach-merritt syndrome with a giant liver hemangioma cause serious coagulation disorders, which presents thrombocytopenia, hemolytic anemia, prolonged prothrombin time and hypofibrinogenemia, this association is rare in adult’s patients and most report adult’s patients are single case report [1].

Treatments are liver resection, enucleation and liver transplantation. Abnormalities in hematological and coagulative systems can return to normal after operation, A total of 17 cases were reported, with a mean age of 49.8 years (27–83 years). The size of the hemangioma was an average of 23.4cm [2, 3, 4].

A 46 years old woman without estrogen therapy was presented to the emergency department for abdominal pain in the right hypochondrium with feeling of abdominal heaviness and generalized mucocutaneous pallor, a computed tomography scan objectified a hepatomegaly by the presence of a well limited tissue formation tacking the contrast delimiting a central hypo dense zone occupying all the right liver, mensuration’s was 29 cmX17.86cmX16.21cm (Figure 1).

 She had a coagulation disorder of thrombocytopenia at 160 /mm3, anemia at 7g/L, prolonged prothrombin time at 74 percentage, and hypofibrinogenemia 69 mg/ld., D-dimers was very high at 10500 μg/L for a normal at 500 μg/L, factor V at 65 percentage, Liver enzymes were normal, tumors markers (ACE, CA19, 9, aplhafoeotprotein) were normal too and her albumin level was 30 g/l. In view of the size of the lesion and of the low hepatic volume remaining after hepatectomy an associated liver partition and portal right vein ligation for staged hepatectomy was done. Abnormalities in hematological and coagulative systems were improved after ligation and returned to normal after hepatectomy.

Hemangioma is the most common benign liver tumor; accounting for 73 percentage of all benign liver tumors [5], however the association with an adult Kasabach-merritt syndrome is too rare, which is more common in children and uncommon in adults, over 30 years only 17 cases was reported in literature. Giant hemangioma is all tumors with size Greater then 10 cm [6], Hemangioma are more common in middle-aged women 49.8 years, the average size was 23.4 cm; a surgical treatment was realized in 73 percentage of patients [7], 

For patients with adult Kasabach-Merritt syndrome associated with giant liver hemangioma, intratumor thrombus consumed a large amount of coagulation factors, linked to an abnormal and proliferating endothelium 

resulting in coagulation disorders and thrombocytopenia, which was a valid indication for surgical treatment [8, 9, 10], For patients with Kasabach-Merritt syndrome associated with liver hemangioma, the tumor is usually extremely giant, posing a significant risk during liver resection.

There was still a debate on the surgical procedures for liver hemangioma; those who are for liver resection [11, 12] and who are for enucleation.

The role of arterial embolization as a treatment for primary and secondary hepatic neoplasms is Well established [13, 14] for hepatic hemangioma and Kasabach-Merritt syndrome there are limited Data, but one report utilizing intravenous cryoprecipitate plus infusion of intra-arterial thrombin and aminocaproic acid resulted in complete stasis within the hepatic hemangioma. Unfortunately, in most cases, embolization is only temporarily effective in reducing the size of the hemangioma and improving the Bleeding diathesis [13].

Currently, the primary treatments for liver hemangioma include; liver resection, enucleation, and interventional embolism, liver transplantation has been used to treat Kasabach- Merritt syndrome associated with giant liver hemangioma, with good recovery of coagulation and platelets after transplant [15]. Enucleation is associated with a few intra-abdominal complications; it should be preferred when location and size permit [16] if not a liver resection is required.

Adult Kasabach-merritt syndrome associated with a giant liver hemangioma is uncommon, Abnormalities and disorders in hematological and coagulative system return to normal after surgery. Different therapeutic options are available; enucleation, liver resection, embolization then resection and hepatic transplantation.
