title: Melanin pigmentation of the larynx.
abstract: Five cases of melanosis of the larynx, verified by biopsy, are reported. All occurred in male patients. Melanocytes and melanin-laden epithelial cells were microscopically seen in the laryngeal mucosa. In one case squamous carcinoma coexisted. Current theories on melanin pigmentation at atypical sites are reviewed.
