Fetal rhabdomyoma of the tongue, with a discussion of the two histologic variants of this tumor.

Fetal rhabdomyomas are rare benign tumors of skeletal muscle that must be distinguished histologically from various sarcomas, including rhabdomyosarcoma. They have recently been subdivided into two histologic variants myxoid and cellular fetal rhabdomyomas, respectively. This article describes the sixth fetal rhabdomyoma to be reported in the oral regions, illustrates the histologic features of the two types, and discusses the means of distinguishing these lesions from various other conditions with which they may be confused.
