ABSTRACT
The majority of neuropathies due to systemic diseases do not require a nerve biopsy for diagnosis. Diagnosis is made by clinical evaluation and laboratory data. However, there are a few neuropathies which do necessitate a nerve biopsy for confirmation of diagnosis. These include vasculitic neuropathy, sarcoid neuropathy, sensory perineuritis, leprosy, and lymphomatous neuropathy. Vasculitic neuropathy was discussed in Chapter 6.
