Abstract
-
Glomus tumors are benign neoplasms that are derived from modified smooth muscle cells known as glomus cells. Histologically, it can be subdivided as glomus tumor proper, glomangioma, and glomangiomyoma according to relative proportions of components. Glomangiomyomas are the least frequent type and their overall architectural pattern may resemble glomus tumor proper or glomangioma, but there is a gradual transition from glomus cells to elongated mature smooth muscle cells. This transition is most obvious in the region surrounding large vessels. We present a case of glomangiomyoma of the left upper arm and the left fourth finger, in which ten-year history of two painful, bluish-colored subcutaneous nodules. On histologic examination, this case showed marked smooth muscle cell proliferation around large vessles and mucinous stromal change.
