A 61-year-old presented to the emergency department with lightheadedness. Vital signs included blood pressure of 120/76 mmHg, heart rate of 100 bpm, and oxygen saturation of 99% on room air. Physical examination was normal, except for pallor. The patient had a history of hypertension, well controlled on three different categories of antihypertensives. There was also a history of bleeding diathesis, which was attributed to use of nonsteroidal anti-inflammatory drugs (NSAID). Patient's medical history was unremarkable for trauma, surgery, or instrumentation to the kidneys. Family history did not include bleeding disorders or genetic renal abnormalities.
Laboratory results revealed normocytic anemia with hemoglobin of 70 g/mL, mildly increased serum creatinine of 103 U/L, as well as borderline low serum potassium of 3.5 mmol/L. Further investigation included endoscopy, which revealed a large mass lesion in the cecum, consistent with villous adenoma.
