Hereditary cleft lip/palate and wilms tumor: A rare association

Objective: The association of cleft lip/palate (CLP) with other anomalies is not uncommon, but its association with Wilms tumor (WT) is very rare, especially in a familial pattern. In this report, we present a family in which six members in two generations were affected with CLP, WT, or both. Patients and Results: A male patient presented with right complete CLP. He had a family history of facial cleft and abdominal tumor. Lip repair was performed at 3 months of age. An abdominal mass was noticed at 12 months of age, which proved to be WT. Surgical excision of the tumor and chemotherapy were conducted. He subsequently underwent palate repair. His father had an unrepaired microform cleft lip. Three of his aunts were known to have similar problems: one had both facial cleft and WT, one had WT only, and the other had facial cleft only. One of his cousins also was affected with WT. Conclusions: This is a unique family affected with a rare association of CLP and WT. Pedigree study revealed an autosomal dominant hereditary pattern.
