Methylation class plexus tumor, subclass pediatric A
- Name: Methylation class plexus tumor, subclass pediatric A
- Description: The methylation class "plexus tumor, subclass pediatric A" comprises cases diagnosed as choroid plexus papillomas and atypical choroid plexus papillomas. These tumors occur preferentially supratentorial in the lateral or 3rd ventricle but also infratentorial in or around the 4th ventricle; median age is 0 years (range 0 to 9). Additional characteristic molecular features of this class are not known to date. Numeric whole chromosome changes are frequent in this class, often including gain of chromosome 5, 8, 9, 11, 12, 14, 15, 20 and X (each in over 40% of cases).
- Histological diagnosis: Atypical choroid plexus papilloma (8; 53.3%); Choroid plexus papilloma (7; 46.7%)
- Localisation: supra (11; 78.6%), PF (3; 21.4%)
