Two Cases of Myxoid Change in Decidualized Cutaneous Endometriosis in the Abdominal Scar Following Cesarean Section and immunohistochemical study

Decidualized cutaneous endometriosis infrequently arises in the abscence of pelvic disease. It is described in which the histologic features included cytologic atypia, circumscription of endometrial epithelial cells with glandular or cystically dilated space, mononuclear cells within and around the endometrial nodules, and accompanied myxoid change. This histologic pseudomalignancy is not common and be misinterpreted as metastatic carcinoma or malignant tumors arising from soft tissue due to location of nodule and histologic feature. We have experienced two cases of myxoid change in decidualized cutaneous endometriosis in the abdominal scar following Cesarean section, which is presented with a brief review of the literature.
