Further investigations showed no proteinuria and fecal alpha-1-antytripisin clear- ance was increased. These results were consistent with a PLE. In order to clarify the etiology of exsudative enteropathy, the patient underwent an upper gastrointestinal endoscopy with gastric and duodenal biopsies which were normal.

A B After 1961, as per available literature, less than 200 cases have been reported. It is mainly seen in pediatric patients, usually diagnosed before three years of age, with an equal incidence in both genders (4). Although most cases are sporadic, PIL has been reported in multiple siblings of several families, suggesting a genetic contribution. Fur- thermore, PIL can occur as an isolated disorder or as a part of a syndrome such as Von Recklinghausen, Turner, Noonan, Klippel-Trenaunay-Weber, Hennekan and yel- low-nail syndrome. In a retrospective analysis of 84 cases in 2010, the most common symptoms were limb edema, diarrhea, ascites and lymphedema, present in 78, 62, 41 and 22%, respective- ly (7).
