A case of congenital infantile fibrosarcoma of the right hand.
Congenital infantile fibrosarcoma is a rare soft-tissue malignant tumor that usually presents as a mass involving the arm or leg. We report a case of congenital fibrosarcoma on the right hand of a newborn infant. The patient was a 12-day-old male. From the time of delivery, he had a red tumor on his dorsal right hand. The tumor was initially associated with bleeding within a hemangioma and compressed. The course was observed. It appeared that the tumor might be malignant because it increased in size to 10 x 8 x 3 cm, and ulceration and bleeding appeared on the surface after 10 days. A biopsy suggested a fibrosarcoma. The tumor was resected 32 days after birth at the narrow margin in consideration of preservation of function. However, a recurrence was observed under the graft after 2 weeks and another resection was performed. Because the tumor had passed through the interosseous muscle and invaded the palm of the hand, the middle finger, ring finger, and little finger had to be amputated. One year and 7 months postoperatively, no recurrence or metastasis has been observed.
