Adenomyomatosis of the gallbladder in childhood.
Adenomyomatosis of the gallbladder (ADMG) is defined as an acquired disease characterized by localized or diffuse hyperplastic extensions of the mucosa into, and often beyond, the thickened gallbladder muscular layer (Rokitansky-Aschoff's sinuses). In recent years, attention has been drawn to its malignant potential. The occurrence of ADMG has never been reported in children. The authors report the case of a 5-year-old boy with symptomatic ADMG, who was successfully treated by laparoscopic cholecystectomy.
