• An otherwise normal 11-year-old boy had greatly reduced acral pain and temperature sensation with associated trophic damage. The disorder was present at birth, and there was no family history of similar problems. The patient also exhibited complete anhidrosis. The case may be an "overlap" between what has been termed as hereditary sensory neuropathy (HSN) type 2 and type 4.
