Is Cronkhite-Canada Syndrome necessarily a late-onset disease?

Cronkhite-Canada Syndrome is a non-inherited, non-congenital disease characterized by juvenile hamartomatous gastrointestinal polyps with a typically late onset. In the case described herein the disease was diagnosed in a 17-year-old male with type I diabetes and thalassaemia minor, in coincidence with severe symptomatic intestinal candidiasis. Following the disappearance of the mycosis and correction of the protein and electrolyte imbalance, the ectodermal abnormalities returned to normal and the patient remained asymptomatic during a 7-year follow-up period, despite proteinuria resulting from membranous glomerulopathy. The concept that Cronkhite-Canada Syndrome is a late-onset disease should probably be reconsidered as it may remain asymptomatic, and thus not diagnosed, for a long a time.
