A case is reported in whom the triad generalized lymphedema, nail dystrophy, and pleural effusion was associated to protein-losing enteropathy. This combination, not previously described, was also characterized by exacerbations of pleural effusion with recurrent episodes of broncho-pneumonia. Albumin turnover study showed depletion of the total body pool, decreased catabolic rate, and elevated albumin removal through the gastrointestinal tract. During bronchopneumonia, increased capillary permeability due to pleural involvement may worsen the basic deficit of pleural lymphatic drainage.
