She reports that her gastrointestinal symptoms have worsened and she now has recurrent bouts of diarrhea with little relation to food intake. Upon further questioning, the patient reports she is also experiencing occasional flushing episodes as well. Her blood pressure is 110/70 mmHg, heart rate is 66/min, and temperature is 36.8 °C (98.24 °F). On physical examination, the patient appears tall and slender. The physician also notes diffusely hypertrophied lips that contain numerous yellowish-white, sessile, painless nodules. The patient's eyelids are also thickened and everted. Laboratory studies are remarkable for elevated concentration of serum calcitonin. Development of which of the following tumors is this patient most at risk for?]] |
