What Is a Skin Biopsy?

A skin biopsy involves removing a small sample of skin—typically from the lower leg or thigh—to examine nerve fiber density and function. This procedure helps identify nerve damage, inflammation, and degenerative changes that may contribute to neurological symptoms such as:

Chronic pain, burning, or tingling sensations
Unexplained numbness or weakness
Temperature sensitivity
Unexplained autonomic dysfunction (sweating abnormalities, dizziness, or blood pressure issues)

What Conditions Can a Skin Biopsy Help Diagnose?

Small Fiber Neuropathy

  • Affects the small nerve fibers responsible for pain and temperature sensation

Peripheral Neuropathy

  • Damage to the peripheral nerves from conditions like diabetes, autoimmune diseases, or infections

Neurodegenerative Disorders

  • Assists in diagnosing Parkinson’s disease

Autoimmune & Inflammatory Disorders

  • Helps detect conditions like vasculitis, lupus, and sarcoidosis
