Urticaria-like skin flushing

Gastric carcinoids can produce histamine-like skin flushes because they may secrete histamine. Carcinoids, also known as carcinoid tumors, are a group of pheochromic cells that occur in the gastrointestinal tract and other organs. The clinical, histochemical, and biochemical characteristics of new organisms can vary depending on where they occur. Such tumors can secrete biologically active factors such as serotonin (serotonin), kinins, and histamine, which cause vascular movement disorders, gastrointestinal symptoms, heart and lung diseases, etc., and are called carcinoid syndrome. ).
