Definition
Beckwith-Wiedemann syndrome (BWS) is a complex overgrowth disorder caused by a number of genes that are subject to genomic imprinting. A high incidence of solid childhood tumors is seen in patients that present with BWS.
Characteristics
Diagnostic Criteria
Beckwith-Wiedemann syndrome is a disorder first described by Beckwith in 1963 at the 11th annual meeting of the Western Society for Pediatric Research. Later, Wiedemann and Beckwith described the syndrome in more detail [2]. BWS is characterized by a great variety of clinical features, among which are abdominal wall defects, macroglossia, pre- and post-natal gigantism, earlobe pits or creases, facial nevus flammeus, hypoglycemia, renal abnormalities, and hemihypertrophy. BWS patients have a 7.5% risk of developing (mostly intra-abdominal) childhood tumors. Tumors most frequently found are Wilms tumor(WT), adrenocortical carcinoma (ACC), rhabdomyosarcoma (RMS), and hepatoblastoma (HB). Patients can be classified as having...
