Hemangioma hepático congénito gigante: síndrome de Kasabach-Merritt / Giant Congenital Liver Hemangioma: Kasabach Merritt Syndrome

Resumen Los hemangiomas son las proliferaciones más frecuentes en la edad pediátrica, y el hemangioma hepático es de los más comunes entre los viscerales. El diagnóstico precoz es importante para orientar el tratamiento. Se presenta el caso de un neonato con compromiso ventilatorio secundario al efecto de una masa gigante, que ecográficamente correspondió a un hemangioma hepático. Se realizó resección quirúrgica y, ulteriormente, fue enviada a patología, que confirmó el diagnóstico.

Abstract Hemangiomas are the most frequent proliferations in children, and liver hemangiomas are the most common among those in the viscera. Early diagnosis to focus treatment is important. We present the case of a neonate with compromised breathing secondary to the effect of a giant mass that echographically appeared to be a hepatic hemangioma. Surgical resection and subsequent pathology confirmed the diagnosis.

Intrathoracic hemangioendothelioma presenting as refractory unilateral pleural effusion and thrombocytopenia

A variety of diseases are associated with the development of unilateral pleural effusion. Although unilateral pleural effusion is common, refractory unilateral pleural effusion is rare. It is important to make an accurate diagnosis using proper diagnostic tools. Thrombocytopenia is one of the rare conditions occurring from various diseases such as severe infection or autoimmune diseases. It can be life-threatening if accurate diagnosis and treatment are delayed and be a clue to accurate diagnosis in differential diagnosis from refractory pleural effusion. Kasabach-Merrit syndrome (KMS) is often accompanied by extensive vascular tumors and characterized by consumptive coagulopathy with profound thrombocytopenia. It is also important to have a high index of suspicion for the diagnosis. We report a case of KMS in a 2-month-old female infant with a vascular tumor on her left intrathoracic cage, who had presented refractory unilateral pleural effusion and thrombocytopenia. Initially, the patient was diagnosed as having complications of severe infection, and a chest tube was inserted for aggressive treatment. However, her unilateral pleural effusion persisted, and thrombocytopenia and hypofibrinogenemia were refractory. Chest imaging revealed an infiltrating large vascular tumor involving the cardiac border, diaphragm, and chest wall. The patient’s unilateral pleural effusion was misidentified as an infectious condition at the initial stage. As a result of the ultrasonography-guided biopsy, it was revealed to be Kaposiform hemangioendothelioma. The patient was cured after treatment for KMS.
