It is often associated with Cowden syndrome and is pathognomonic for this disease.
It was described by Jacques Jean Lhermitte and P. Duclos in 1920.
Epidemiology
Lhermitte-Duclos disease is a rare entity; approximately 220 cases of LDD have been reported in medical literature. It's most common in 3. and 4. decade of life.
Etiology
Cowden disease is caused by mutations of PTEN gene.
