Ultrastructural aspect of myocarditis: its relevance for the diagnosis.

abstract：:A metastasizing carcinoid of the gastric stump found 25 years after Billroth II gastric resection for duodenal ulcer is described. Electron microscopy and optical endocrine cell staining proved the tumor to be composed of enterochromaffinlike (ECL) cells. This unusual combination further shows that, at variance with m...
