RESUMEN
UNLABELLED: We report a case of warfarin embryopathy. This disease affects more than 6% of fetuses exposed in utero to a vitamin K antagonist. OBSERVATION: A child whose mother was treated with acenocoumarol because of a mechanical heart valve presented with signs of warfarin embryopathy. He showed chondrodysplasia punctata with telebrachydactyly, facial dysmorphism with nasal hypoplasia, a cataract, and a bilateral pyeloureteral junction syndrome. COMMENTS: Characteristics of this drug induced embryopathy are reminded, while bearing in mind the conflict of interests between the mother and the fetus. The mechanisms of this embryopathy are debated in light of the recent knowledge concerning fetal metabolism of vitamin K.

INTRODUCTION: Hypercalcemia associated with subcutaneous fat necrosis of the newborn is a well known but rare event. CASE REPORT: A newborn with a history of cesarean section, fetomaternal infection, neurological and respiratory distress was admitted with anorexia, adynamia, vomiting, polyuria and polydipsia at the age of 37 days. Physical examination showed red and violaceous infiltrated skin lesions. Skin biopsy revealed focal areas of fat necrosis with crystal-like structures. Calcium and 1,25 (OH(2) ) vitamin D serum levels were increased. Diagnostic of subcutaneous fat necrosis of the newborn with symptomatic hypercalcemia was made. Evolution was favorable after treatment including furosemide, prednisone and a diet low in calcium and vitamin D. DISCUSSION: Hypercalcemia must be detected in infants with subcutaneous fat necrosis. This major complication may have fatal outcome. Treatment of hypercalcemia includes dietary changes associated with classic treatment of hypercalcemia. Routine evaluation of serum calcium level is essential.

BACKGROUND: Behçet's disease is a multisystem illness rarely including cardiac involvement. We report a case characterized by a mural cardiac mass in the right ventricle. CASE REPORT: A 14-year-old boy presented with a full set of symptoms leading to the diagnosis of Behçet's disease. Echocardiography revealed a 60/120 mm mass in the right ventricle. With anticoagulation therapy, prednisone and cyclophosphamide, the cardiac lesion progressively resolved. DISCUSSION: This observation is exceptional because cardiac mas is rarely described in Behçet's disease. Surgical exploration, which is usually indicated to exclude malignant process, is not necessary in such cases.
