A Case of Infantile Hepatic Hemangioendothelioma/Hemangioma at Maharaj Nakorn Chiang Mai Hospital.

Infantile hepatic hemangioendothelioma/hemangioma is the most common benign hepatic vascular tumor of infancy, comprising approximately 1% of all childhood tumors. The tumor can present during the fetal or neonatal period as a hepatic mass. Common presentations include abdominal distension and a palpable hepatic mass. Clinico-radio-pathological correlation is essential for a definite diagnosis. Frequent complications such as congestive heart failure, thrombocytopenia, anemia, and Kasabach-Merritt syndrome should be investigated. Chemotherapy has been reported as an effective treatment option. Surgical resection has an essential role for symptomatic patients with medical treatment failure or other certain conditions such as refusal to take medication. Furthermore, prenatal diagnosis is essential for better patient outcomes due to prompt treatment in the neonatal period. We report a case of a female infant at 39 weeks of gestation who was delivered from a 32-year-old mother. The infant was in utero diagnosed by ultrasonography with a hepatic mass, most likely hemangioma. The mass was resected after birth and it was diagnosed as infantile hepatic hemangioendothelioma type II. The course of the disease was excellent and the patient was cured after treatment.
