Multiple congenital mesenchymal tumorsMultiple vascular leiomyomas in several organs of a newborn

Abstract

A case of multiple congenital mesenchymal tumors is described. The tumors involved the lungs, the small intestine, the colon, and the subcutaneous tissues. Twenty cases are reviewed, and comparisons are made. The features in the 20 cases are basically similar, and resemble one another; the tumors are multiple, congenital, and mesenchymal in origin. It is felt that the present case, perhaps as well as Bartlett's 4 cases, represents a different age of the tumors from those of the other cases, and shows a greater degree of differentiation.
