This is a case report of a 6-year-old female child with asymptomatic multiple squamous papillomatosis involving the hypopharynx and the entire length of the oesophagus. Total spontaneous regression of the papillomata occurred within 2 years of presentation. Associated asymptomatic laryngeal papillomata were removed by suction diathermy under general anaesthesia. The diagnosis was confirmed by direct microlaryngoscopy, oesophagoscopy, barium swallow and histology. The laryngeal hypopharyngeal and oesophageal lesions were identical histologically and macroscopically.
