Title Alternative A case of duodenal diverticulitis in a patient receiving tocilizumab for rheumatoid arthritis
FullText URL 134_166.pdf
Author Iwamuro, Masaya| Baba, Yuki| Kawahara, Yoshiro| Okada, Hiroyuki|
Abstract  A Japanese woman was diagnosed with rheumatoid arthritis at the age of 41. At the age of 56, her rheumatoid arthritis worsened and a subcutaneous injection of tocilizumab and oral prednisolone was administered, which led to an improvement of arthritis. At the age of 57, right lower abdominal pain and vomiting suddenly appeared. Abdominal computed tomography showed a parapapillary diverticulum in the descending duodenum. The diverticulum was filled with residue, and an inflammation of the surrounding adipose tissue was observed; no free air was found. The patient was diagnosed with duodenal diverticulitis and treated with antibiotics, which resulted in an uneventful recovery. The maximum value of CRP was 1.88㎎/dL on the third day of hospitalization. Esophagogastroduodenoscopy performed on the 8th day of hospitalization revealed a parapapillary diverticulum with adhesion of pus and redness of the mucosa at the opening of the diverticulum, consistent with diverticulitis. This case highlights that diverticulitis in infrequent areas such as the duodenum may occur in patients who are treated with tocilizumab. In addition, inflammation of diverticulitis may be underestimated because abnormal laboratory values such as those induced by inflammatory reactions are less likely to occur during tocilizumab treatment.

Abstract Herein, we report two patients with autoimmune gastritis who had undergone multiple esophagogastroduodenoscopy procedures for 17 and 9 years, respectively, before their diagnosis. Instead, they had been diagnosed with and treated for Helicobacter pylori-associated gastritis. The correct diagnosis was made when scatterings of tiny whitish protrusions in the gastric mucosa were detected on esophagogastroduodenoscopy. Our findings suggest that scattered tiny whitish bumps may be a clue to the diagnosis of autoimmune gastritis.

Title Alternative Magnified observation of spontaneous morphological changes of duodenal follicular lymphoma
FullText URL 128_111.pdf

Abstract  A 63-year-old Japanese woman was diagnosed with duodenal follicular lymphoma. The initial esophagogastroduodenoscopic examination with magnifying observation revealed opaque white spots and enlarged whitish villi. Nine months later, esophagogastroduodenoscopy showed that the size of the lymphoma lesion decreased, and only opaque white spots were visible. The histological analysis of biopsy samples obtained during the initial endoscopy examination showed both neoplastic follicles and an inter-follicular infiltration of lymphoma cells, whereas the biopsy samples obtained at the endoscopy performed 9 months later showed only neoplastic follicle formation. These results suggest that the magnifying endoscopic features may reflect the underlying pathological mechanisms : enlarged whitish villi are probably due to lymphoma cell infiltration in the inter-follicular area, and opaque white spots are probably caused by neoplastic follicle formation.
