Abstract

Myxofibrosarcoma represents one of the most common soft tissue sarcomas of the extremities in adult and elderly patients. However, it only rarely occurs in the chest wall. A 58 years old woman presented with a huge painless lump (8 ${\times}$ 6.5 cm) in the right lower parasternal area which recurred a few months following excision from General surgery of our hospital. Histology showed an infiltrative deep seated dermal and subcutaneous tumor. It had a distinctive lobular growth pattern with prominent myxoid change and moderate cellularity. Tumor cells were spindleshaped with varying degrees of pleomorphism and frequent mitotic figures. Numerous blood vessels with curvilinear growth pattern were also seen. Immunostains for S-100, CD68, Mac 387, and FX IIIa were all negative, but positive for Vimentin. The histologic feature was of an intermediate grade myxofibrosarcoma. Wide excision was performed and recovered in good condition without any physical disabilities and was discharged at one month later. Currently she is waiting for the skin graft without chemotherapy and radiotherapy.

점액성섬유육종은 성인과 장년의 환자에서 사지의 가장 흔한 연조직 육종의 하나를 나타내고 있다. 하지만 이 종양은 흉벽에서는 희귀하게 발생한다. 58세의 여자환자가 본: 병원 일반외과에서 절제에 이은 수개월 후 재발하여서 우측 아래 흉벽에서 8${\times}$6.5 cm의 거대 종양덩어리를 보였다. 조직은 침윤성 심부에 위치한 피하층 종양이었고 명확한 점액성 변화와 중등도의 세포 충실성을 보이면서 명확한 엽성 성장을 보였다. 종양세포는 다양한 정도의 세포양상과 유사분열을 갖고 있는 방추형세포였고 궁형의 혈관양상을 보였다. 5-100, CD68과 Mac387 그리고 FX IIIa의 면역염색은 음성이었고 Vimentin 염색은 양성을 보였다. 조직양상은 점액성 섬유육종의 증간등급이었다. 광범위절제를 하였고 한달 후 퇴원하였는데 항암제나 방사선치료 없이 결손부위의 피부이식을 준비하고 있다.
