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.

The purpose of this study was to assess the effect of heat therapy on cutaneous blood flow and skin temperature at pre-auricular region. Moist heat therapy and ultrasound therapy were applied to 20 healthy subjects(male: 10, female: 10). Cutaneous blood flow and skin temperature before and after heat therapy were measured with laser doppler flowmetry and thermocouple. The results were as follows ; 1. Cutaneous blood flow and skin temperature were significantly increased after moist heat therapy and ultrasound therapy. 2. In application of moist heat therapy, cutaneous blood flow and skin temperature were more increased and maintained longer than in ultrasound therapy. 3. Before heat therapy, cutaneous blood flow and skin temperature were higher in male. 4. There was no significant gender difference in changes of cutaneous blood flow and skin temperature after heat therapy. In conclusion, both moist heat therapy and ultrasound therapy increased cutaneous blood flow and skin temperature significantly, and moist heat therapy was more effective to increase cutaneous blood flow and skin temperature and to maintain increased cutaneous blood flow and skin temperature. There was no significant gender difference in the effect of heat therapy on cutaneous blood flow and skin temperature.

The purpose of this study was to assess the effects of the superficial heat therapy on the cutaneous blood flow and the skin temperature at pre-auricular region. Two types of the superficial heat therapy-moist hot pack & infrared lamp- were applied to 20 healthy subjects(male: 10, female: 10). For each subject, the two parameters of cutaneous blood flow and skin temperature were measured before and after heat therapy, using laser doppler flowmetry(LDF). The author analyzed the differences of the effects between the two therapies and also characteristics of responsiveness between the two parameters. The results were as follows : 1. The two parameters were significantly increased after both superficial heat therapies. 2. Skin temperature showed a maximum peak immediately after both superficial heat therapies, but cutaneous blood flow showed a maximum peak 4 minutes after both superficial heat therapies. 3. Increased cutaneous blood flow after application of moist hot pack lasted longer than infrared lamp. 4. Increased skin temperature after both superficial heat therapies lasted for 60 minutes, but increased skin temperature after infrared lamp decreased more rapidly than moist hot pack. 5. Amount of changes in cutaneous blood flow after infrared lamp was larger in female than in male, but no significant gender difference was found since 20 minutes after infrared lamp. Both moist hot pack and infrared lamp showed favorable effectiveness in raising cutaneous blood flow and skin temperature. Moist hot pack was slightly superior in maintaining this effect.
