Three unrelated stillborn infants (cases 1-3) are presented here with a distinct constellation of multiple anomalies: namely, multiple pterygia involving chin-to-sternum, cervical, axillary, antecubital, crural and/or popliteal areas, flexion contractures of multiple joints, small chest, hydrops, characteristic abnormal facial appearance with hypertelorism, markedly flattened nasal bridge with hypoplastic nasal alae, cleft palate, micrognathia, apparently low-set malformed ears, short neck with a cystic hygroma at the back of the neck and head, and pulmonary and cardiac hypoplasia. Radiographic studies, in addition, showed scalp edema, microbrachycephaly, flattened mandibular angle, lack of normal curvature at the cervico-thoracic junction, marked bony fusion of posterior spinous processes of older fetuses (cases 1, 2), thin crowded ribs, markedly hypoplastic scapulae, hypoplastic iliac wings, ischia and pubic bones, undermodeling of tubular bones, and radio-ulnar synostosis. Histologic studies of the skeletal system showed cartilaginous and bony fusion of the spinous processes (cases 1, 2), fusion of epiphyseal cartilages of distal humerus and proximal ulna, a poorly developed joint space, an abnormal growth plate, and weak safranin staining of the resting cartilages (cases 1, 2). To the best of our knowledge, this pattern of anomalies constitutes a previously undescribed syndrome. Prenatal diagnosis of this entity is possible by ultrasonographic studies on the basis of nonimmune fetal hydrops, a cystic hygroma at the back of the head and neck, diminished fetal activity, short and fixed limbs, and/or maternal hydramnios. Three additional cases (cases 4-6) are also presented to show a possible heterogeneity of this syndrome.
