A case of cesarean scar endometriosis with myxoid
change and decidualization in a 24 year-old pregnant is
presented. Patient in the second trimester complained
of mass in the scar tissue of previous cesarean section.
At 40th week of gestation, pregnancy was terminated
and subcutaneous mass was removed. Microscopic examination
revealed a lesion with lobular pattern and
prominent myxoid change in the stroma. Each lobule
was containing dilated cystic spaces resembling lymphatic
vessels. Also signet-ring like vacuolated cells were
present in myxoid stroma. The diagnosis was decidualized
scar endometriosis with myxoid change. However,
histological features of the lesion may cause diagnostic
confusion with benign or malignant tumors such as
myxoma, myxoid sarcomas and mucinous adenocarcinoma.
Immunohistochemical study and thus recognizing
cellular characteristics could help to prevent this
misinterpretation.
