[Extraskeletal plasma cell tumors (author's transl)].

Extraskeletal plasmacytomas are very rare malignant plasma cell tumors. They often seem to arise from a pathologic plasma cell reaction to an antigenic stimulation and are characterized by the variety of their locations and the frequent absence of monoclonal dysproteinemia. The authors are reporting three new observations of extraskeletal plasma cell tumors. Some pathological, biological and pathogenic features of these tumors are emphasized.

[Esophagogastroduodenal localizations of Crohn's disease are frequent].

The purpose of this study was to determine the endoscopic features, actual frequency and consequences of upper digestive involvement in Crohn's disease (CD). Between April 1973 and April 1985, one or several upper digestive tract endoscopies with biopsies were performed in 129 of 195 patients admitted for ileal and/or colorectal CD. Endoscopic lesions were small and superficial: aphtous and superficial ulcerations, or erythematous areas. The diagnosis of upper digestive involvement was probable in 36 of the 129 patients who underwent upper endoscopies (28 p. 100), certain (microscopic evidence of granuloma) in 21 patients (16 p. 100). Lesions were isolated or multifocal but their preferential sites were the antrum and proximal duodenum. Histologic study of biopsies showed that granuloma were as frequent in upper as in lower intestinal lesions of CD. A frequency of 20 p. 100 seems to us to be more correct than the 5 p. 100 usually admitted. In our experience, upper digestive involvement in CD could not be regarded as a pejorative prognostic factor. It was sometimes possible to identify colitis or a peptic ulcer disease as a lower or upper digestive manifestation of CD, respectively.

[Bile plug syndrome. A rare cause of curable cholestatic jaundice in the infant].

An eight week old baby who presented with a cholestatic jaundice had a bile plug in the ampulla of Vater. The plug was removal via a transduodenal approach. The bile plug syndrome is a rare cause of extrahepatic biliary cholestasis and is different from the inspissated bile syndrome in which the involvement is predominantly hepatocellular.
