Gastric neuroendocrine tumour, atrophic gastritis and autoimmune haemolytic anaemia: a case report and review.

Gastric neuroendocrine tumours are rare. We describe a unique case of a 66-year-old male patient who presented with shortness of breath and malaise, eventually attributed to severe autoimmune haemolysis in the context of atrophic gastritis and multiple type-1 gastric neuroendocrine tumours. The patient had also positive anti-cardiolipin antibodies. A favourable outcome was attained with corticosteroids plus subtotal gastrectomy for the treatment of the underlying neoplastic disease. This case illustrates that the differential diagnosis of any associated causes of autoimmune haemolytic anaemia can be challenging, and may extend to unexpected conditions.
