Adult polyglucosan body disease (APBD) presents with neurological and autonomic dysfunction. Skin biopsy offers a less invasive diagnostic alternative to nerve biopsy for APBD.

Area of Science:

  • Neurology
  • Pathology
  • Genetics

Background:

  • Adult polyglucosan body disease (APBD) is a rare genetic disorder.
  • It is characterized by progressive neurological deficits, including peripheral neuropathy, upper motor neuron signs, and autonomic dysfunction.

Observation:

  • A case study detailing a patient with APBD presenting with typical clinical symptoms.
  • Diagnostic findings from sural nerve biopsy revealed intra-axonal polyglucosan bodies under electron microscopy.
  • Inclusions were identified as branched filaments (6-8 nm) primarily within myelinated nerve fibers.

Findings:

  • Skin biopsy from the axilla confirmed the diagnosis by showing similar polyglucosan inclusions in myoepithelial cells of apocrine glands.
  • This supports skin biopsy as a diagnostic method for APBD.

Implications:

  • Skin biopsy may serve as a less invasive and simpler diagnostic alternative compared to sural nerve or brain biopsies for APBD.
  • This finding could potentially simplify the diagnostic pathway for patients with suspected APBD.
