Myxoinflammatory Fibroblastic Sarcoma

Myxoinflammatory fibroblastic sarcoma of the soft tissues is a rare low-grade tumor of uncertain origin that most often occurs on the extremities of adults. The tumor predominantly involves the subcutaneous tissues of the hands and feet. Despite being a rare neoplasm, owing to its varied histologic appearance, myxoinflammatory fibroblastic sarcoma should be differentiated from various benign and malignant soft-tissue lesions. Myxoinflammatory fibroblastic sarcoma has been well described in pathology journals but not in the surgical literature. We report a case of myxoinflammatory fibroblastic sarcoma in a 19-year-old man with a plantar ulcer lesion in his left foot. To our knowledge, this is the first reported case in the literature involving the epidermis. (J Am Podiatr Med Assoc 100(6): 497–501, 2010)

Low-grade fibromyxoid sarcoma, also known as Evans tumor, is a low-grade sarcoma that most commonly arises in the deep soft tissue of the proximal extremities or trunk in young adults. It is very rare in the viscera as a primary site, with only a few cases reported in the literature. Here, we present a case of Evans tumor occurring in an unusual and rarely reported location; an intrathoracic mass arising from the diaphragmatic pleura.

Abstract Ameloblastic fibrosarcoma (AFS) is a rare, aggressive malignant odontogenic tumor. AFS is seen most frequently in second and third decades of life. We are reporting a case of a low grade AFS in a 21-year-old male complaining of a painless swelling in the right side of the maxilla. The patient was treated with surgical excision followed by radiotherapy, which is considered the most effective approach for most of soft tissue sarcomas. AFS has a high-reported recurrence rate (up to 37%); therefore, long-term surveillance for recurrence is crucial.

Rare Case Report

Chondrosarcoma is a rare variant of bladder tumor and one of the rare types of soft tissue sarcoma. This case happened on a 36-year-old male who complained of lumps in his lower abdomen, accompanied by difficulties in passing urine and painful urination, without hematuria. We performed TURBT and histopathological examination showed low-grade chondrosarcoma. The patient was diagnosed with low-grade bladder chondrosarcoma. The patient was treated for chemotherapy and radiotherapy. However, after undergoing one cycle of chemotherapy, the patient refused to continue the therapy.

Dermatofibrosarcoma protuberans (DFSP) is a malignant fibrohistiocytic tumor that appears exclusively on the skin. It is a low-grade malignant soft tissue tumor of subcutaneous tissues that has a propensity for local recurrence but seldom metastasizes. It may rarely occur on the head and neck accounting for less than one percent of total head and neck malignancies. We present a man with a giant DFSP on the face. Oncological, functional, and aesthetic aspects are set forth.

Extraskeletal chondroma is a benign cartilaginous tumor that occurs predominantly in the soft tissues near small joints of the hands and feet. There are rare reports of the lesion in other sites, such as the head, neck, trunk, oral cavity, larynx, and pharynx. We present a case of an axillary mass in a 15-year-old girl who underwent MRI examination and resection, with the ultimate diagnosis of an extraskeletal chondroma, in order to expand the differential diagnosis of an axillary soft tissue mass in an adolescent.

Background: Ultrasonography is useful for distinguishing between benign and malignant soft-tissue tumors. However, no study has focused on its usefulness in the differential diagnosis between low-grade and high-grade soft-tissue sarcomas. We conducted a retrospective study to determine the usefulness of the parameters of ultrasonograph and to develop a practical scoring system for distinguishing between high-grade and low-grade sarcomas. Methods: Twenty-two cases of low-grade and 43 cases of high-grade malignant soft-tissue sarcoma were enrolled. Ultrasonography parameters including the longest diameter, depth of the tumor, echogenicity, tumor margin, and vascularity defined according to Giovagnorio’s criteria were analyzed as factors to distinguish between the two types of sarcoma. Significant factors were entered into a multivariate model to define the scores for distinction according to the odds ratio. The usefulness of the score was analyzed via receiver operating characteristic analyses. Results: In univariate analysis, tumor margin, echogenicity, and vascularity were significantly different between low- and high-grade sarcomas. In the multivariate regression model, the odds ratio for high-grade vs. low-grade sarcoma was 8.8 for tumor margin, 69 for echogenicity, and 8.3 for vascularity. Scores for the risk factors were defined as follows: 1, ill-defined margin; 2, hypoechoic echogenicity; and 1, type IV in Giovagnorio’s criteria. The sum of each score was confirmed by receiver operating characteristic analysis. The area under the curve was 0.95, with a cut-off score of 3, indicating that the scoring system was useful. Conclusion: The ultrasonography parameters of tumor margin, echogenicity, and vascularity are useful for distinguishing between low- and high-grade sarcomas.

First Case

Sclerosing epithelioid fibrosarcoma (SEF) is a rare, aggressive soft-tissue tumor, commonly occurring in upper and lower extremities, the limb girdle, and the head and neck, which shows morphologic and molecular overlap with low-grade fibromyxoid sarcoma. For SEF in soft tissues, 100 case reports have been published. To our knowledge, the present case is the first to be reported in English literature for a primary SEF of the stomach with a rare FUS-CREM fusion. We report a case of gastric SEF in a 35-year-old female who presented with nonspecific symptoms, including night sweat, cough, and iron deficiency anemia for the past few months. Further workup showed, on computed tomography, a large, heterogeneously enhancing and centrally necrotic left upper quadrant mass, which measured approximately 8.4 cm. A laparoscopic partial gastrectomy with distal pancreatectomy and splenectomy was performed. Histological examination and immunohistochemical staining suggested the diagnosis of primary gastric SEF, which was later confirmed by sarcoma fusion panel showing FUS-CREM fusion. In this article, we report this first case of SEF in the stomach with a rare FUS-CREM fusion, which has been previously reported only once in SEFs of soft tissue.
