초록

Infantile myofibromatosis is a rare benign neoplasm which is usually found in males. Most cases of the infantile myofibromatosis are discovered before the age of two years and about half of cases are found at muscle, tendon, and soft tissue of head-neck region. However, it is especially uncommon that infantile myofibroma occurs at the pre-auricular area. In current case, we report a twenty two months old male patient with $2.5{\times}1.5cm$ sized pre-auricular mass at right side. It was surgically removed and histologically showed broad bundle of plump myoid spindle cells with eosinophilic cytoplasm and weakly positive smooth muscle actin expression in myoid cells. In three months of follow up, there was no recurrence.
