The authors present a case of primary intracranial extraosseous myxoid chondrosarcoma without any attachment to the cranium or the meninges. The clinical and radiological findings of the primary intraparenchymal tumor are described with a review of the literature concerning cranial and intracranial myxoid chondrosarcoma.

Primary cardiac myxosarcoma is extremely rare, which is uncommon in primary cardiac tumors. We report a primary cardiac myxosarcoma in a 40-year-old female patient who was admitted to the hospital because of exertional dyspnea and palpitation. The patient underwent emergency operation immediately after the intracardiac (left atrium) tumor was discovered by an echocardiography. Palliative tumor removal was done and final pathologic diagnosis was primary cardiac myxosarcoma. She was discharged without complications.

Many different abnormalities, such as, neoplasm, infection, traumatic hematoma, or congenital or immune myopathy, may be found in the paravertebral muscles. However, neoplasms of paravertebral muscle are an uncommon cause of back pain. Such neoplasms may arise from local lesions or due to metastatic spread from a distant malignancy. The differential diagnoses of a primary soft tissue malignancy and metastatic spread from a skeletal muscle tumor are important. In cases of soft tissue sarcoma, histopathological findings and surgical margins are both related to local recurrence and metastasis, therefore, percutaneous needle biopsy may be helpful before surgical excision. A degree of surgical excision is decided based on considerations of muscular function and histopathological findings.

A case of primary malignant fibrous histiocytoma of the breast is reported. The patient was a 48-yr-old woman with a huge tumor involving almost the entire left breast. The central portion of her left breast was already rotted by extensive necrosis and inflammation. She was treated by radical mastectomy and axillary lymphadenectomy to level I. Pathologic examination supported by an immunohistochemical staining confirmed the tumor as malignant fibrous histiocytoma of giant cell type. Axillary lymph nodes were free from tumor metastasis. She had not taken any postoperative adjuvant therapy. The metastasis to lungs was found 2 months after the operation, and she died within 6 months.

OBJECTIVETo study the clinicopathological features, immnophenotype and differential diagnosis of low-grade fibromyxoid sarcoma (LGFMS).
METHODSThe clinical, radiological and pathological features of 9 cases of LGFMS were reviewed.
RESULTSThe patients consisted of six males and three females with ages ranging from 11 to 65 years (mean 31.4 years). Clinically, most cases presented as slowly growing painless masses located in the extremities, trunk and neck. Two cases had a history of a rapid recent enlargement. Three cases presented with recurrent diseases after incomplete resection. Ultrasound showed heterogeneous signal. Precontrast CT and T1-weighted MRI showed a nodular mass of low to isodensity, while contrast-enhanced CT and T2-weighted MRI demonstrated contrasting zonal areas of hypo/hyperintensity. The tumors measured 3 to 16 cm (mean 7.7 cm), with a fibrous to myxoid appearance on cut surface. Histologically, they were composed of alternating collagenous and myxoid areas. A transition between the two areas could be identified. Giant rosette-like structures were observed in 3 cases. The center of the giant rosettes was composed of eosinophilic collagen, which showed centrifugal in arrangement. There was also gradual transition between the giant rosettes and the fibromyxoid component. On high magnification, the tumor was composed of ovoid to spindle-shaped cells with hyperchromatic nuclei. Nuclear atypia was inconspicuous. The tumor cells were arranged mostly in interlacing fascicles or whorls. Vessels were not prominent and necrosis was absent. Immunohistochemically, the tumor cells showed unique staining for vimentin, consistent with a fibroblastic differentiation.
CONCLUSIONSLGFMS is a distinctive low grade fibroblastic sarcoma of young adults. Recognizing the characteristics of the rare entity may help to avoid misdiagnosis. Wide local excision is recommended to avoid local recurrences.

10.Myxoid Chondrosarcoma of the Sinonasal Cavity in a Child: a Case Report.

Chondrosarcomas are malignant tumors of cartilage that rarely involve the sinonasal region, and myxoid chondrosarcoma is a rare histologic variant of chondrosarcoma that usually occurs in the soft tissue of extremities. Although several case reports and results of small series of chondrosarcomas in the sinonasal region in children are available, myxoid type chondrosarcoma is extremely rare. We recently experienced a case of low grade myxoid chondrosarcoma involving the sinonasal cavity in a 10-year-old boy, and here we report its radiologic-pathologic findings. In this case, chondroid calcification on CT and septal and marginal enhancement on MRI suggested a chondrosarcoma. Whole body PET-CT demonstrated no definite metastatic lesion and a low peak standardized uptake value primary tumor. However, no definite distinguishing imaging features were observed that distinguished low grade myxoid chondrosarcoma from conventional chondrosarcoma.
