This is a very rare, possibly benign uterine tumor that is characterized by a cytologically bland and largely mitot-ically inactive proliferation of spindle cells in a myxoid matrix. The main differential diagnostic considerations include myxoid leiomyoma and leiomyosarcoma and endometrial stromal neoplasm with myxoid stroma. All inflammatory myofibroblastic tumors reported in the largest series were ALK-positive, which is similar to what has been described to occur in other sites. " All uterine mesenchymal neoplasms studied were ALK-negative, including smooth muscle and endometrial stromal tumors and carcinosarcomas.
