[Familial Waldmann's disease]. / Maladie de Waldmann familiale.

We report the observation of a mother and her daughter who presented edema, hypoprotidemia and lymphopenia due to protein-losing enteropathy. Radiological, endoscopic and histological investigations revealed the diagnosis of primary intestinal lymphangiectasis or Waldmann's disease. Dietary treatment with middle chained triglycerides was effective. Familial cases are rarely described.
