BACKGROUND: von Hippel-Lindau disease is an autosomal dominant disorder characterized by the development of hemangioblastomas in the cerebellum, spinal cord, and retina, renal cell carcinoma and cysts, pancreatic cysts, and pheochromocytoma. METHODS: We have studied a series of 36 French patients affected with von Hippel-Lindau disease pheochromocytoma. Thirty (83%) of them were diagnosed as having von Hippel-Lindau disease because the disease occurred in a familial von Hippel-Lindau disease setting; six (17%) were diagnosed as having von Hippel-Lindau disease because they displayed another characteristic manifestation of that disease. RESULTS: The mean age at pheochromocytoma diagnosis was 29 +/- 14 years (5 to 62 years). Bilateral tumors were documented in 15 (42%) cases, paraganglioma was associated with adrenal pheochromocytoma in four cases, and malignant pheochromocytoma occurred in three cases. Prevalence of pheochromocytoma revealing von Hippel-Lindau disease was 20 (53%) out of 36. In six cases pheochromocytoma was the only manifestation of the disease. CONCLUSIONS: In the interest of the patients themselves and of family members who are at risk, search for von Hippel-Lindau disease must be systematic in the presence of pheochromocytoma. Basic checkup may be completed with familial inquiry, ophthalmoscopy, cerebral magnetic resonance imaging, abdominal ultrasonography, and computed tomography-scan for detection of latent lesions. In the future, after characterization of von Hippel-Lindau disease gene mutations, molecular diagnosis is going to be possible in individual patients.
