Congenital multiple plaque-like glomangiomyoma in trunk--a case report.

Congenital glomus tumor is a rare variant of glomus tumor, and glomangiomyoma is the least frequent histological type of glomus tumor. We present a case of congenital multiple plaque-like glomangiomyoma in an 11-year-old child with multiple diffuse plaques on his right lateral trunk. Histopathologic study showed a picture of typical glomus cell undergoing transition to smooth muscle cell. After literature review, this might be the first case report of congenital multiple plaque-like glomus tumor in trunk with histological appearance of a glomangiomyoma.
