Neuropathy and Fabry's disease.

Fabry's disease is a multisystem disorder that is commonly associated with a painful, debilitating neuropathy. The common coexistence of arthralgias and an elevated erythrocyte sedimentation rate may lead to the misdiagnosis of a rheumatic condition. We report a 38-year-old man who was evaluated for progressive neuropathy and limb pain in the setting of longstanding arthralgias, presumed juvenile rheumatoid arthritis, and past renal transplantation. Histopathologic assessment of nerve and muscle biopsy specimens led to the diagnosis of Fabry's disease, thus allowing the patient to receive enzyme replacement therapy that may slow progression and preserve the transplanted kidney.
