Three mm punch biopsies of skin undertaken confirmed multifocal small fiber neuropathy, suggested by loss of protein gene product 9.5 immunolabeled nerve fibers in the dorsum of left foot, over the extensor digitorum brevis muscle (2.1 fibers/mm of skin; normal >3.0) and left upper thigh at the level of ischial tuberosity (3.8 fibers/mm of skin; normal >6.0), and low normal intra‐epidermal nerve fiber density (IENFD) in the calf segment, 10 cm above the lateral malleolus (4.7 fibers/mm of skin; normal >4.3). Scale bar represents 20 μm. Interpretation of IENFD was done by Corinthian Reference Laboratory, Benbrook, TX [Color figure can be viewed at wileyonlinelibrary.com]
