NF3 develops in adulthood and is often associated with chronic pain. Dysesthesia and paresthesia may also be present. Common localizations include the spine, peripheral nerves, and the cranium."

It typically progresses for one to two years and then stabilizes. Hyperpigmentation is usually the only symptom but there are isolated reports of other symptoms, involving mostly the central nervous system, musculoskeletal system, and heart. While most cases of LWNH are sporadic, apparent genetic transmission rarely has been described. A few people with LWNH have been diagnosed with chromosomal mosaicism."
