Fibromyoma Cutis. Presented by Dr. Vincent P. Burby.
This white man presents a tumor of the right groin. This tumor mass has been present for 17 years, growing slowly, and now extends from the anterior superior spine to the symphysis. The protuberant mass over the symphysis is of recent origin.
Microscopic study with hematoxylin-eosin and van Gieson's stain show the structure of a mild myoma cutis in which the muscular tissue has been partly replaced by fibrous tissue. There are, however, patches of smooth muscle fibers present in different portions of the tumor growth. Also evident throughout the tumor is a quantity of connective tissue, which in some areas appears to separate the smooth muscle bundles. The covering epithelium extends fairly deeply in several areas, but no loose cell masses are apparent and there are no signs of malignancy. Mild inflammatory involvement of the perivascular areas is apparent.
