Abstract

Chronic occupational exposure to lead leads to significant mucocutaneous changes in lead factory workers. Although lead poisoning rarely manifests as melanonychia, clinicians should be aware of this atypical presentation, especially in high-risk groups such as those working in the battery industry. Dear Editor, A 25-year-old man who worked in the battery industry presented with a 2-year history of (a) gingival brown hyperpigmentation, (b) hyperpigmented macules on the upper extremities and total melanonychia (b),[1] accompanied by headache, paraesthesia and insomnia.[2] (c) Onychoscopy revealed regular longitudinal pigmented bands.
