Lhermitte-Duclos disease
Lhermitte-Duclos disease, abbreviated LDD, is a rare neuropathology.
It is also known as dysplastic cerebellar gangliocytoma[1] and dysplastic gangliocytoma of the cerebellum.
General
- Cerebellar lesion.
- May be associated with Cowden syndrome.[2]
- Rarely bilateral.[3]
- ICD-O code: 9493/0
Microscopic
Features:[4]
- The outer (molecular) layer has increased cellularity.
- Purkinje cells absent.[1]
- Large (polygonal) cells with round nuclei and prominent nucleoli in the inner (granular) layer - key feature.
- +/-Microcalcifications.
IHC
- Synapto+ve.
- Calbindin+ve.
- PTEN-ve.
- MIB-1 almost absent.
