The rest two cases with smooth margin of the serosal surface showed no significant adhesion with adjacent other structures.* Location of endometriosis related with adenomyosis Separated from adenomyosis : 18 casesAbutting adenomyosis : 41 casesWe categorized adenomyosis into two groups - adneomyosis by invasion of endometriosis and adenomyosis with coincided endometriosis.Twenty-nine...\nConclusion\nInvasion of endometriosis may cause serosal sided adenomyosis and usually shows adhesion between uterus, endometriosis and surrounding organs.This information of invasion and adhesion may behelpful to determine the treatment plan of endometriosis.\nReferences\nTamai, K., et al.
