Superior sternal cleft associated with PHACES syndrome: postnatal sonographic findings

"Pitted" lesions in dermatology

Cutaneous pitting, dimpling, or depressions are frequently dealt with in clinical practice. Such lesions may be primary manifestations of a disorder or develop as secondary changes during the course of the disease. Cutaneous pitting may be a manifestation of certain genodermatoses and internal disorders when it serves as a marker of such conditions. This article describes various types of pitted lesions affecting the ectodermal structures (skin, nails, and teeth) and their clinical significance along with brief description of the associated conditions.

Thoracic defects: cleft sternum and Poland syndrome

Defects of the thoracic cage with bone and/or muscle deficit are relatively rare and can present a real risk depending on the severity of manifestations. Cleft sternum results from failed midline fusion of the sternal halves that leaves the heart and great vessels unprotected, and is commonly associated with craniofacial hemangiomas. Correction is recommended during the neonatal period when compliant thorax allows direct suturing of the divided sternum. Sternal foramen requires precaution during biopsy and acupuncture as well as forensic awareness. In addition to the thoracic defect, Poland syndrome can be associated with hand anomalies, dextrocardia, renal agenesia, and various tumors. Age and gender, together with the degree of the defect, define the method of surgical correction.

Segmental Neurovascular Syndromes in Children

The concept of segmental vascular syndromes with different, seemingly unrelated, diseases is based on the embryology of the neural crest and the mesoderm migration of cells that share the same metameric origin. Migrating patterns of these cells link the brain, the cranial bones, and the face on the same side. A somatic mutation developing in the region of the neural crest or the adjacent cephalic mesoderm before migration can, therefore, be postulated to produce arterial or venous metameric syndromes, including PHACES, CAMS, Cobb syndrome, and Sturge-Weber syndrome. Although these diseases may be rare, their relationships among each other and their postulated linkage with the development of the neural crest and the cephalic mesoderm may shed light on the complex pathology and etiology of various cerebral vascular disorders.

Prenatal ultrasonography and neonatal imaging of complete cleft sternum: a case report

The prenatal diagnosis of a complete cleft sternum was established in a fetus of a twin pregnancy at 22 weeks' gestation. We present the prenatal imaging and correlation with postnatal magnetic resonance imaging and high-resolution ultrasonography. Thinned and depressed midline anterior chest wall transmitting the cardiac pulsation was the clue to the diagnosis, and the defective sternum could be identified on close sonographic observation. Successful surgical correction was undertaken at 2 months of age. There were no major associated abnormalities such as ectopia cordis or midline abdominal wall defects.
