Peutz-Jegher syndrome in childhood: need for updated recommendations?

We reviewed our institution's experience with Peutz-Jegher syndrome (PJS) in children to determine whether current recommendations on timing of screening and follow-up should be modified.

We reviewed the charts of all of the children with a diagnosis of PJS at our institution from 2000 to 2011 abstracting data on intussusceptions events, polyp characteristics, Sertoli cell (SC) tumors, family history, imaging, and interventions.

Of 14 children identified, 10 were boys. Median age at first clinical evaluation was 4.5 years, and family history and/or mucocutaneous pigmentation were the 2 most common factors stimulating screening. Median age at first screening test was 5 years (range 1-16), and at first polyp identification, 5 years (range 1 to 18). There were 7 intussusception events in 5 children, with median age of 10 and range 5 to 16 for first event. Two boys had SC tumors at 8 and 11 years. Polyps were identified during initial screening in 9 of 14 patients. Polyps were found in the stomach or duodenum in 5 (36%), small bowel in 7, (50%) and colon in 3 (21%) children. Large polyps were identified in 9 children at median age of 7 years.

Polyps causing significant clinical consequences can occur frequently in children with PJS younger than 8 years. Revised guidelines should consider initial screening at age 4 to 5 with capsule endoscopy and upper and lower endoscopy as well as evaluation for SC tumors and re-evaluation whenever symptoms suggest polyp-associated complications.
