Nerve biopsies were performed in four patients with suspected chloroquine induced neuromyopathy. Three of the patients were treated with high doses of chloroquine for connective tissue disease, while one patient was taking this drug as malaria prophylaxis. Morphological studies demonstrated the presence of segmental demyelination and remyelination in all cases. Cytoplasmic inclusions were observed in Schwann cells, in perineurial and endothelial cells, and in some interstitial cells. They were never observed within axons. Occasional curvilinear profiles were seen in perineurial and Schwann cells. Perineurial calcifications were observed in two cases. The results of this morphological study suggest that chloroquine neuropathy is essentially due primary involvement of Schwann cells.

UI MeSH Term Description Entries
D008297 Male Males
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D009410 Nerve Degeneration Loss of functional activity and trophic degeneration of nerve axons and their terminal arborizations following the destruction of their cells of origin or interruption of their continuity with these cells. The pathology is characteristic of neurodegenerative diseases. Often the process of nerve degeneration is studied in research on neuroanatomical localization and correlation of the neurophysiology of neural pathways.
