[Castleman's disease with isolated renal location: clinical case]

Abstract

In a review of the literature the authors delineate the present nosographic and descriptive characteristics of Castleman's disease. They then report the case of an adult woman who came to their attention because of persistent, low-grade fever, sweating, malaise and polyarthralgia. Laboratory data evidenced increased acute-phase reactants, polyclonal hypergammaglobulinemia, and anemia due to "chronic disease". Diagnostic imaging documented a right renal mass. A nephrectomy was performed. Histopathological studies confirmed hyaline-vascular type Castleman's disease with monoclonal B-cell lymphoproliferation. The clinical and laboratory anomalies regressed after surgery and continue to be absent after 1 year of follow-up. The authors conclude their presentation by pointing out the peculiarities of this case that do not correspond with the traditional distinctive features of the disease.
