Case Reports
Duodenal Obstruction Caused by the Long-term Recurrence of Appendiceal Goblet Cell Carcinoid.
A 38-year-old Japanese man who had been diagnosed with appendiceal carcinoid and undergone ileocecal resection 8 years before presented with duodenal obstruction caused by a submucosal tumor-like appearance. He was diagnosed with long-term recurrence of appendiceal goblet cell carcinoid (GCC) with a multi-morphological pattern based on the histological assessment of a duodenal biopsy and his previously resected appendix. ⋯ The GCC recurred at the nearby ileo-colic anastomosis and invaded the duodenum. This late recurrence might have resulted from the unique features of his GCC, which contained cells with different degrees of malignancy.

We herein report two cases of autoimmune gastritis without complete atrophy of the corpus. Both were positive for anti-parietal cell antibodies. ⋯ Histopathological examinations of these nodules showed focal and patchy atrophy and preserved fundic glands with parietal cell pseudohypertrophy. Follow-up endoscopy and a repeated biopsy demonstrated the development of gastric atrophy on the greater curvature in both cases.

Cerebral Infarction and Myalgia in a 75-year-old Man with Eosinophilic Granulomatosis with Polyangiitis.
Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare condition of systemic vasculitis of small to medium-sized blood vessels. We herein report the case of a 75-year-old man who presented with hemiplegia on his right side due to cerebral infarction following myalgia and a high fever. ⋯ His hemiplegia improved rapidly after corticosteroid therapy. This case suggests that EGPA should be a differential diagnosis of cerebral infarction with myalgia and eosinophilia.

Case Reports
Recurrent Fulminant Myocarditis Accompanied by Lymphoid Follicle Formation in Myocardium.
A 76-year-old man developed repeated fulminant myocarditis in a short period, and immunosuppressive therapy was remarkably effective. A pathologic evaluation showed that inflammatory cells had infiltrated the myocardium. ⋯ This is the first report of recurrent autoimmune myocarditis with a lymphoid follicle in the myocardium. These findings may suggest a novel pathogenesis of myocarditis.
