다국어 초록 (Multilingual Abstract)

A 5-year-old boy presented with pea-sized vascular lesions on the neck, 2 months ago. The lesions consisted of 6 mm width, 2 mm height sized, indurated, yellowish and firm lesion. The lesion was asymptomatic and had been enlarged in size. He had no specific personal medical history, nor the family history of the lesion. The lesion was suspected as molluscum contagiosum, so we tried to remove through curettage and it was easily removed as whole mass without residual mass tissue visually. In histopathologic examination, mass was consisted with bland-looking spindle cells, with lower than 1 per 10 HPF of mitotic activity. We suspected myofibroma or fibroma, so we performed immunohistochemical staining. The results were positive in SMA stain, negative in CD 34 stain, and negative in desmin stain. Cutaneous tumors are relatively common in children, and most are benign. Spindle cell tumor with cutaneous involvement in children include myofibroma, a variety of cutaneous fibroblastic and myofibroblastic tumors, smooth muscle tumors and other variants. The differential diagnosis with a combination of clinical and histological features and immunohistochemistry is important.
