A physical examination revealed no abnormalities except for skin eruptions on the bilateral elbows, knees and hips (Figure 1).
Light micrograph of a sural nerve biopsy and a bone scintigram. Light micrograph of a sural nerve biopsy showing a moderate reduction in the density of large myelinated fibers, with (A) abnormally thin myelin relative to axonal caliber (arrows) in a cross section (bar=30mum) and (B) teased fibers with short, thinly myelinated internodes (arrows), indicating remyelination (bar=100mum). (C) A bone scintigram showing an abnormal accumulation of 99mTc in both of the sternocostoclavicular joints and the right clavicular region.

A sural nerve biopsy showed a moderate reduction in density of large myelinated fibers (Figure 2A), with remyelinated fibers comprising 21.8% of all teased fibers (Figure 2B). His sternocostoclavicular joints and right clavicular region showed active uptake of the radioisotope 99mTc, consistent with osteitis of the clavicle and manubrium (Figure 2C).
