title: Ovarian cysts and tumours in infancy and childhood.
abstract: Cysts and tumours of the ovary are not uncommon in childhood. In 33 years between 1950 and 1982 106 patients were operated on at Alder Hey Children's Hospital and the Royal Liverpool Children's Hospital. Of these 71 were pre-menarchal. The mode of presentation, pathology and diagnostic difficulties of the pre-menarchal lesions are reviewed. The value of ultrasound scanning has become apparent in recent years. Most cysts and tumours are benign, but dysgerminomas are the most common malignant tumours encountered. Even when there is evidence of spread of the tumour the prognosis in these remains reasonably good.
