A new diagnostic sampling method in pure neural leprosy: the scraping of the myelin sheath.
Pure Neural Leprosy (PNL) is a form of leprosy characterized by neural involvement without any skin lesions.1 PNL affects about 3%–10% of patients with leprosy and it can occur in any spectrum, although it is more frequent in the tuberculoid type.2 We present a case of a patient affected by PNL diagnosed through the scraping of myelin sheaths of the ulnar nerve, Ziehl-Neelsen (ZN) staining, and Polymerase Chain Reaction (PCR).
