mes·en·chy·mo·ma
(mes'eng-kī-mō'mă),Rarely used term for a neoplasm in which there is a mixture of mesenchymal derivatives, other than fibrous tissue. A benign mesenchymoma may contain foci of vascular, muscular, adipose, osteoid, osseous, and cartilaginous tissue; such neoplasms are sometimes classed under a compounded name, for example, angioleiomyolipoma, and the like, but the broader term may be preferred. A malignant mesenchymoma may also occur as a similar mixture of two or more types of mesenchymal cells that are malignant (other than fibrous tissue cells).
