Carcinoma of the larynx in childhood.
The unusual case of a 12-year-old boy with well differentiated in situ, and focally invasive squamous carcinoma of the larynx is reported, together with a review of the medical literature. In addition to this one, 54 cases of laryngeal carcinoma in children 15 years of age or younger have been reported since 1868. All were squamous except for one adenocarcinoma of a laryngeal minor salivary gland. Carcinoma of the larynx in children parallels that of adults in terms of squamous histology, predominantly vocal cord involvement, pattern of local spread, and response to treatment. However, the incidence of female patients is higher in childhood (40% of childhood cases vs. less than 10% of adult cases), and risk factors, except previous irradiation of papillomas, are rare. Although unusual, carcinoma of the larynx in children is probably more common than thought and the diagnosis should be considered in any case of a child with persistent hoarseness or cough.
