Whipple's disease is caused by a ubiquitous Gram-positive bacillus, Tropheryma whipplei. The disease is extremely rare, with only 1,000 cases reported worldwide. Classic Whipple's disease is characterized by a multisystemic involvement with joint (arthralgias) and gastrointestinal (abdominal pain, diarrhea, and weight loss) symptoms. We present a case of a 48-year-old male who had a constitutional syndrome associated with an exuberant bilateral pleural effusion. The small bowel biopsy identified a rod-shaped bacterial cologne in the macrophage cytoplasm, positive for periodic acid-Schiff (PAS) staining, and the polymerase chain reaction (PCR) exam identified the DNA of Tropheryma whipplei. The patient was medicated with two weeks of endovenous antibiotherapy with ceftriaxone 2 g per day, followed by one year of oral trimethoprim 160 mg and sulfamethoxazole 800 mg twice daily. He presented good evolution with total resolution of symptoms.
