Phacomatosis pigmentovascularis type 2b (phacomatosis cesioflammea) with double superior vena cava, abdominal varicosities, and natal tooth: Novel associations.

Phacomatosis pigmentovascularis is characterized by coexistent extensive cutaneous vascular (capillary) and pigmentary anomalies. We describe a 2-month-old infant presenting with classic features of phacomatosis pigmentovascularis 2b (phacomatosis cesioflammea). He was also found to have hitherto unreported associations in the form of extensive venous anomalies presenting as striking abdominal wall varicosities and persistent left superior vena cava and natal tooth.
