Lhermitte-Duclos disease associated with Cowden syndrome.

Abstract: Lhermitte-Duclos disease or dysplastic gangliocytoma of the cerebellum, is a rare cerebellar lesion, which can cause mass effects in the posterior fossa. It may occur sporadically, or in association with Cowden syndrome. Cowden syndrome or multiple hamartoma-neoplasia syndrome, is an uncommon autosomal dominant condition characterized by mucocutaneous lesions and systemic malignancies. We report two patients with Lhermitte-Duclos disease and associated Cowden syndrome. The clinical, radiological and histopathological features and management strategies of this rare disease complex are discussed. [Copyright &y& Elsevier]
