Primary malignant fibrous histiocytoma (MFH) of the chest wall is rare. We report a case of primary MFH arising from the chest wall, which was thought to be a metastasis or myeloma. The imaging study revealed a single mass of the chest wall involving a rib. Resection and chest wall reconstruction was done. The histologic diagnosis was storiform-pleomorphic primary MFH. Although MFH of the chest wall is an uncommon pathology, it should be considered in the differentiation of a single bony destructive lesion involving the rib with a soft tissue component.

We report a case of giant cell tumor originating from the anterior arc of the rib. The tumor and the surrounding chest wall were completely resected, and the chest wall defect was covered with Marlex mesh. Giant cell tumor of the bone usually originates from the epiphysis of long bones. Even when the tumor occur in ribs, it usually occur in the posterior aspect. However, giant cell tumor should be included in the differential diagnosis of a tumor originating from the anterior arc of the ribs.

We report on a 41-year-old woman with a chest wall desmoid tumour who was successfully treated with a computed tomography (CT)-guided steroid injection. She presented with a palpable mass in the right upper chest wall and was treated by surgical excision and postoperative radiation therapy due to recurrence of the mass at the surgical site. At 20 months after the second operation, a recurrent mass was again detected in the anterosuperior portion of the previous surgical site on CT. We performed a CT-guided steroid injection weekly for 4 weeks by applying a mixture of 3 mL of triamcinolone acetonide (40 mg/mL) and 3 mL of 1% Lidocaine, administering 4-6 mL of the mixture, to the lesion. Six months later, CT showed a marked decrease in the size of the mass.
