Abstract Gartner's duct cyst is a rare condition consequent to an unfinished disappearance of the mesonephric duct in females. In this report we present three cases of mesonephric duct remnants cysts: two of these were originated from its proximal part ,paraooforon, whereas in the third case the cyst was originated from its paraurethral distal end. These lesions are an uncommon and extremely rare manifestations in paediatric age and more in neonatal age: therefore we believe very interesting and useful to report these cases, describe their clinical data, debate the embryogenic origins, discuss diagnostic and therapeutic problems according to international literature.
