Onion bulb structures, toluidine blue stain. Hypertrophic changes with onion-bulb formation occur most commonly as a result of recurrent segmental demyelination and are most often seen in hereditary neuropathies (such as the fairly common Charcot-Marie-Tooth disease). The schwann cell doesn’t wrap around the axon properly and as a result, you get these strange involutions in the histological section.
