Abstract

We present a case of length-dependent sensory axonal polyneuropathy due to lead exposure from a cosmetic product. Serial follow-ups showed a direct relationship between the lead level, clinical symptoms, and the polyneuropathy. Our patient had a relatively short-term exposure to lead after misusing a hair dye on his beard. Nerve conduction studies showed a predominantly axonal sensory neuropathy that correlated with lead blood levels and reached 3 times the upper limit of normal. The patient had an unexpected sensory predominant neuropathy. He had a full recovery after stopping the lead-containing product. Blood lead levels were noted to be below previously reported toxic levels. No other systemic signs of lead toxicity were noted. This could be related to the mucosal route of absorption inducing a reversible injury at lower than previously reported lead levels and after a shorter duration of exposure.
