History And Clinical Findings:
A 56-year-old woman presented with pronounced petechia. She complained about recurrent fever and night sweat for two weeks, having felt unwell during the past years.
Investigations:
Laboratory examinations showed thrombocytopenia, leukopenia and considerably elevated liver enzymes. Antinuclear antibodies and antibodies against double-stranded DNA were positive. Sonography showed a slightly enlarged liver with multiple surrounding lymph nodes, splenomegaly and chronic-atrophic thyroiditis. Gastroscopy revealed several polypes which were immunohistochemically classified as neuroendocrine tumors (NET).
Diagnosis, Treatment And Course:
Systemic lupus erythematosus (SLE) with involvement of several organs was diagnosed and high doses of steroids were given. The steroid was then gradually reduced and changed to azathioprine. The NET were removed endoscopically.
Conclusion:
Neuroendocrine tumors are rare and localised to the stomach in only 2 - 4 %. Only three cases of gastric NET in the context of SLE with autoimmune gastritis have been reported so far in the literature.

Gastritis II: Pathophysiology
Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
