In fetal life myxomatous tumors are met with in those sub-cutaneous tissues from which fatty tissue is later developed the tissue appears as a homogeneous, structureless, gelatinousmass. The majority of the cells present are angiilar and stellate, withlong anastomosing prolongations; others are indistinct (owing to therefractorv nature of the intercellular substance), oval, spheric, or fusi-form in shape. The blood-vessels are readily located, but are few innumber. Frequently, l)etween the cells fine elastic hbers can be demon-strated.

Myxomata usually occur aftermiddle life, are of moderately slow growth, may be single or multiple(commonly multiple), vary in size (rarely large), and not uncommonlyrecur after removal. This return may be due to imperfect removal;after which the remaining myxomatous elementsgrow with increased activity. Myxomata, whenarising in the submucous or subcutaneous tissues,may be pedunculated or sessile; rarely, themass is lobulated. Primarily, they are benigntumors; occasionally such a tumor may becomesarcomatous and the presence of myxomatousmasses in sarcoma (myxosarcoma) is frequentlyobserved.
