Granular-cell myoblastoma of the oral cavity

ABSTRACT

The granular cell myoblastoma is an uncommon lesion that occurs in many parts of the body; the oral cavity, particularly the tongue being the most common location. Whether the lesion is reactive or neoplastic remains to be determined but it is almost always innocent possessing practically no malignant potentials. Nevertheless, the lesion may simulate a malignant growth both clinically and pathologically. A correct pre-operative recognition is essential to avoid a major operation in a lesion that responds well to simple excision
