[Bilateral renal cell carcinoma of von Hippel-Lindau disease associated with von Willebrand disease: a case report].
A 42-year-old man diagnosed with von Willebrand disease 7 years earlier visited his home doctor with a chief complaint of gross hematuria. Abdominal ultrasonography showed bilateral renal tumors. He was referred to our hospital on June 15, 1993. His mother also had von Hippel-Lindau disease and was treated by hemodialysis after bilateral nephrectomy. The examination and imaging revealed bilateral renal cell carcinoma of von Hippel-Lindau disease associated with von Willebrand disease. Partial nephrectomy and enucleation for a small tumor on the right side and enucleations for five tumors on the left side were performed. Histological diagnosis of all tumors were renal cell carcinoma, clear cell subtype, grade 1 approximately 2. The patient has been well without local recurrence or distant metastasis for 16 months since the operation. This is the first case of bilateral renal cell carcinoma of von Hippel-Lindau disease associated with von Willebrand disease in Japan.
