RESUMO
BACKGROUND: We report a rare case of a large congenital hemangioma (CH) in the maxillofacial region in a female neonate that caused thrombocytopenia and heart failure. With close multidisciplinary collaboration, the congenital hemangioma was successfully resected with good results. CASE SUMMARY: The patient was delivered at gestational age of 36 wk by cesarean section due to cephalopelvic disproportion and lack of onset of labor (birth weight: 2630 g). A right-sided facial tumor was detected in the fetus during routine antenatal ultrasound examination of the mother at 32 wk of gestation. Physical examination revealed a 7 cm × 7 cm × 3 cm hard, dull purple-colored mass on the right maxillofacial region. The mass was tense and had prominent surface telangiectasias. Laboratory investigations revealed reduced hemoglobin and platelet count, and increased activated partial thromboplastin time, prothrombin time, and thrombin time. International normalized ratio, fibrin degradation products, and D-Dimer levels were significantly increased. Thromboelastography showed increased alpha angle, mean amplitude, and the clot formation speed. Thyroid-stimulating hormone level was significantly elevated. The patient was administered prednisone, propranolol, euthyrox, vitamin K1, milrinone, and digoxin. After operation, cefepime was administered for anti-infection and propranolol was prescribed at discharge. CONCLUSION: We report a rare case of CH in the right maxillofacial region causing thrombocytopenia and heart failure.
