Nerve
Histiocyte: Free in endoneurial space

Histiocyte: With lipid droplets & myelin debris
|
Histiocyte: Outside Schwann cell basal lamina & Myelin sheath
Demyelinating Neuropathy

Histiocytes: Inside Schwann cell basal lamina
Demyelinating Neuropathy
A Schwann cell process neighbors the macrophage

Histiocytes
One large cell, with lipid debris, is inside a Schwann cell basal lamina
A second, smaller histiocyte (Below) is in the endoneurium
