A 60-year-old Woman With an Incidentally Discovered Right Renal Mass

      A 60-year-old woman presented to our clinic for evaluation of a right renal mass, incidentally discovered on a computed tomography (CT) scan obtained during a workup for shortness of breath. Her medical history was significant for hypertension, hyperlipidemia, hypothyroidism, and asthma. She had undergone several abdominal surgeries, including laparoscopic gastric banding, splenectomy, hysterectomy, and bilateral salpingo-oophorectomy. She denied a history of tobacco, heavy alcohol, or illicit drug use. She had no family history of kidney disease or genitourinary malignancy. On a review of systems, she reported intermittent nausea, vomiting, and dyspepsia but denied fevers, night sweats, weight loss, gross hematuria, dysuria, or a change in bowel habits. Her vitals signs were within normal limits, and her body mass index was 32.4 kg/m2. Her abdomen was soft, not distended, and without palpable masses, although several surgical scars were present. Routine laboratory tests, including complete blood count, electrolytes, creatinine, coagulation studies, and urinalysis, were performed. The complete blood count with differential demonstrated mild thrombocytosis (473 K/μL) and leukocytosis (13 K/μL) but was otherwise normal. The results from the remainder of the laboratory studies were also within normal limits.
