[Two resected cases of malignant fibrous histiocytoma originated from the thoracic soft tissues].

Two resected cases, a 56-year-old man and a 49-year-old man, of malignant fibrous histiocytoma originated from the soft tissues of chest wall were reported. In both cases, MFH was histologically diagnosed prior to our radical operation. One patient received an incisional biopsy and the other was a recurrent case after excisional resection in other hospital. We resected the whole chest wall together with the tumor sufficiently apart from the tumor margin. In one patient the defect of chest wall was reconstructed with the material made of bone cement which sandwiched between 2 sheets of marlex heavy mesh and covered by latissimus dorsi muscle flap on it. The other was reconstructed with single sheet of marlex heavy mesh and covered by rectus abdominis muscle flap. Recurrence was not seen in either of two patients, in spite of the general acknowledgment that MFH recurs frequently and locally. We considered that the extended wide resection including the whole chest wall should be performed, and that marlex heavy mesh and the pedunculated musculo-cutaneous flap was useful for the reconstruction of chest wall defect.

[A case report of solitary bone cyst of rib detected from pathological fracture].

A case of solitary bone cyst of rib was reported. The patient was 28-year-old man who was admitted to our hospital complaining of chest pain caused by pathological fracture of the left 10th rib. Chest x-ray film revealed a solitary cystic lesion of the 10th rib. The tumor was removed by extrapleural rib partial resection and the histological examination confirmed the diagnosis of solitary bone cyst.
