The signs and symptoms of carcinoid syndrome depend on which chemicals the carcinoid tumor secretes into your bloodstream. The most common signs and symptoms of carcinoid syndrome include:

  • Skin flushing. The skin on your face and upper chest feels hot and changes color — ranging from pink to purple. Flushing episodes may last from a few minutes to a few hours or longer.

    Flushing may happen for no obvious reason, though sometimes it can be triggered by stress, exercise or drinking alcohol.

  • Facial skin lesions. Purplish areas of spiderlike veins may appear on the nose and upper lip.
  • Diarrhea. Frequent, watery stools sometimes accompanied by abdominal cramps may occur in people who have carcinoid syndrome.
  • Difficulty breathing. Asthma-like signs and symptoms, such as wheezing and shortness of breath, may occur at the same time you experience skin flushing.
  • Rapid heartbeat. Periods of a fast heart rate could be a sign of carcinoid syndrome.
