Carcinoma of the pharynx in a 10-year-old Jamaican boy

A case of hypopharyngeal carcinoma developing in a ten-year-old Jamaican boy is presented. This is the youngest case of hypopharyngeal carcinoma by many years to be reported as far as can be determined from the available literature. The possible aetiological factors responsible for a cancer developing in one so young and the failure to find involvement of the regional lymphatic system with tumour cells is discussed. The relationship of cancer developing in the unaffected twin of a pair of mono- or dizygotic twins is also examined (AU)
