Craniopharyngioma: Pathological and Molecular Aspects

  • Chapter
Book cover Diagnosis and Management of Craniopharyngiomas

Abstract

Craniopharyngioma (CP) (ICD-O 9350/1) is defined as a benign, partly cystic, epithelial tumour presumably derived from the Rathke’s pouch epithelium. CPs are classified in two forms with distinct morphological and molecular features: adamantinous (ACP) (ICD-O 9351/1) and papillary CP (PCP) (ICD-O 9352/1). Both ACP and PCP are regarded as grade I lesions by the World Health Organisation (WHO) Classification of Tumours of the Central Nervous System (CNS) (Rushing et al., Craniopharyngioma. In: Louis DN, Ohgaki H, Wiestler OD, Webster KC (eds) WHO classification of tumours of the central nervous system, 3rd edn. World Health Organization Press, Geneva, Switzerland, pp. 238–240, 2007). Rare tumours with mixed features of ACP and PCP have been described (Okada et al. 2010; Prieto and Pascual 2013). In this chapter, the pathological features of craniopharyngiomas as well as the latest results of molecular studies will be discussed.
