Incidentally diagnosed renal cancer following investigation for new-onset hyperglycemia

Yukinori Harada, Yuuta Hara


Detecting paraneoplastic syndrome is important for the diagnosis of renal cancer. We present an incidentally detected case of renal cancer during the investigation of new-onset hyperglycemia in a 68-year-old woman. The patient presented with palpitations and weight loss; her laboratory findings showed hyperglycemia, anemia, and elevated C-reactive protein and alkaline phosphatase levels. Computed tomography revealed a right renal cancer. Following tumor removal, her glycemic control improved, and insulin therapy, which was needed preoperatively, was not needed anymore. Clinicians should suspect renal cancer in patients with new-onset hyperglycemia occurring simultaneously with interleukin-6-associated paraneoplastic syndrome.
