["Dysphagia lusoria". Physiopathological discussion apropos of a clinical case]. / "Dysphagia lusoria". Discussion physio-pathologique à propos d'un cas clinique.

We report the observation of a patient suffering from dysphagia lusoria, a dysphagia caused by an anomalous form of the right subclavian artery. The diagnosis was confirmed by aortic arch angiography and cine-oesophagogram. Oesophageal manometric study revealed segmental hypoperistalsis and anti-peristalsis. Dysphagia disappeared with cisapride. This observation suggests that dysphagia lusoria is caused by oesophageal motility disorders and not by vascular compression.

Primary lymphoplasmacytic lymphoma of the liver associated with a serum monoclonal peak of IgG kappa.

We report a case of primary lymphoma of the liver successfully treated by major liver resection. The tumor exhibited the immunohistological features of a B-cell low-grade lymphoma of the lymphoplasmacytic type. Tumoral plasmacytic cells showed cytoplasmic-positive staining for IgG and kappa light chains. In addition, we detected a serum monoclonal peak of IgG kappa, a finding that has not been reported previously. Clinical, pathological, and immunohistochemical data from the literature are reviewed.

[Collagenous colitis: a new case of exudative enteropathy]. / La colite collagène: une nouvelle cause d'entéropathie exsudative.

Collagenous colitis with intestinal protein loss was discovered in a sixty-six year-old female who presented with recurrent and prolonged diarrhea associated with hypoprotidemia, hypoalbuminemia, and increased clearance of alpha-1-antitrypsin. Histologic lesions of collagenous colitis were found during each episode of diarrhea. Biological and histological examinations were normal during the remission phases. Intestinal protein loss appeared to be due to collagenous colitis because of the parallel course of the clinical, biological and histological signs, and because no other cause had been discovered. The possibility of protein exudation, probably secondary to the extent of the epithelial detachment, could be an additional argument for the inflammatory etiology of collagenous colitis.

[Whipple's disease and tuberculosis. A previously unreported association]. / Maladie de Whipple et tuberculose. Une association inédite.

Whipple's disease and pulmonary and lymph node tuberculosis have been diagnosed in a 70 year-old man hospitalized for weight loss and fever. The tuberculous or Whipple's disease-related nature of associated non-necrotizing epithelioid hepatic granulomas could not be determined. The existence of cellular immune defects in Whipple's disease could explain the association with tuberculosis, which has not been previously reported in the literature.
