Abstract

Pathological specimens of 131 surgically removed craniopharyngiomas were obtained from the registry of the National Institute of Neurosurgery, Budapest between 1977 and 1991. The cases were reviewed statistically with reference to their gross and microscopic features and clinical characteristics. Macroscopically, 34% of the tumours were cystic, 23% solid and 43% mixed. Histologically, 38% of the cases belonged to the adamantinous group, 26% were squamous epithelial type, 15% were combined, that is expressing the characteristics of both. In 21% of the cases the surgically removed samples did not contain enough material for correct histopathologic classification. There was no recurrence in the group with the squamous epithelial type tumours, while 59% of the adamantinous, and 36% of the combined craniopharyngiomas recurred. The 5-year survival proportion was 73% at the squamous epithelial, 60% in the adamantinous, and 55% at the combined histological types.
