The histopathology is characterized by a well-circumscribed area of myxomatous tissue in which fusiform or stellate fibroblasts are present {299}. Reticular fibres are sparse or absent. The mucinous material shows alcianophilia at pH 2.5. The histologic differential diagnosis includes soft-tissue myxoma, myxoma-tous change in fibrous lesions, nerve sheath myxoma, and mucous retention phenomenon. The lack of reticular fibres and the sharp delineation distinguishes FOM both from soft-tissue myxoma and from myxomatous changes in fibrous lesions {2615}. Nerve sheath myxoma usually shows a lobular architecture and, conspicuously, contains numerous mast cells. The mucous retention phenomenon is surrounded by a wall of granulation tis sue or an epithelium-lined wall, while the mucoid material contains histiocytic cells; such features are lacking in FOM.
