BACKGROUND: Extremity sarcomas are challenging to manage. Total eradication of tumour has to be balanced with restoration of limb function to prevent mortality and morbidity. Disease-free survival with maximum limb function is the ultimate goal in these patients. MATERIALS AND METHODS: We present a series of ten cases of extremity malignancies, where limb salvage was attempted with microvascular free fibula for limb reconstruction from the period of 2008 to 2015...

Although chondrosarcoma is a common malignant bone tumor, cases arising in the rib are relatively rare. We experienced a case of chondrosarcoma arising in the right 10th rib during follow-up after lung cancer surgery. Although the finding of an osteolytic mass suggested a metastatic bone tumor, 18F-fluorodeoxyglucose positron-emission tomography demonstrated low fluorodeoxyglucose uptake, and a primary bone tumor was suspected. The bone tumor was resected and diagnosed as chondrosarcoma. Four years after resection, there has been no recurrence or metastasis...

INTRODUCTION: Extraskeletal chondrosarcoma (EMC) is a rare, aggressive neoplasm which has been seen in the soft tissue area. This soft tissue sarcoma is classified to myxoid and mesenchymal based on histologic criteria. The mesenchymal subtype has a poor prognosis. In approximately 50% of patient with EMC, we could observe soft tissue lesion and stippled calcification in the conventional radiography. CASE REPORT: In the current paper, we introduced a 47-year-old Iranian male patient having painless, mobile, nontender, and firm mass in left shoulder...

BACKGROUND: EWSR1 rearrangements were first identified in Ewing sarcoma, but the spectrum of EWSR1-rearranged neoplasms now includes many soft tissue tumour subtypes including desmoplastic small round cell tumour (DSRCT), myxoid liposarcoma (MLPS), extraskeletal myxoid chondrosarcoma (EMC), angiomatoid fibrous histiocytoma (AFH), clear cell sarcoma (CCS) and myoepithelial neoplasms. We analysed the spectrum of EWSR1-rearranged soft tissue neoplasms at our tertiary sarcoma centre, by assessing ancillary molecular diagnostic modalities identifying EWSR1-rearranged tumours and reviewing the results in light of our current knowledge of these and other Ewing sarcoma-like neoplasms...

Break-apart FISH probes are the most popular and reliable type of FISH probes used to confirm certain pathological diagnoses. The interpretation is usually easy, however, in some instances it is not so unequivocal. Our aim was to reveal and elucidate the problems occurring in the process of evaluation of the break-apart probe results. Altogether 301 soft tissue sarcomas with confirmed molecular tests using break-apart probes were assessed to reveal the frequency and type of unusual signal pattern. Among 89 synovial sarcoma (SS18) 11%, 12 alveolar rhabdomyosarcoma (FOXO1) 50%, 53 myxoid liposarcoma (DDIT3) 7...

In this study, we present a case of a 52-year-old male with a chondrosarcoma of the left lamina of the thyroid cartilage. Pre-operative evaluations detected typical calcifications and delineated the extent of the tumor. The patient underwent a total laryngectomy to ensure the complete resection of the tumor. The tumor was histopathologically found to consist of chondrocytes in a hyaline cartilage matrix. The patient's post-operative course has been successful apart from the permanent tracheostomy. Herien, we discuss the methods and rationales for the diagnosis and management of and recovery from this rare tumor, and also provide a review of the literature...

Lester Dr Thompson
One of the most challenging diagnostic categories within tumors of the sinonasal tract is the small round blue cell tumors. Biopsies are usually small and limited, resulting in considerable diagnostic difficulty for practicing surgical pathologists. These tumors share several overlapping histologic and immunophenotypic findings while also showing considerable variation within and between cases. Specific tumor site of origin, imaging findings, and clinical findings must be combined with the histology and pertinent ancillary studies if the correct diagnosis is to be reached...

PURPOSE OF REVIEW: The aim of this study was to describe the most recent technical nuances for resection and reconstruction of Grade 1 and 2 laryngeal chondrosarcomas, with a special emphasis on those located at the level of the cricoid plate, which is the site of origin of the vast majority of these rare tumours. RECENT FINDINGS: Even though inherently based on retrospective small clinical series or anecdotal case reports, a number of studies have been recently published focusing on conservative transoral and open-neck surgical procedures aimed at an oncologically sound removal of the tumour together with organ and function preservation...

Behjati et al recently described recurrent mutations of H3F3 genes in giant cell tumors of the bone and chondroblastomas. Both these entities belong to the spectrum of giant cell-rich bone lesions, often presenting a diagnostic challenge for the pathologist. Our aim was to investigate the value of searching for H3F3 mutations in the diagnosis of giant cell tumors of the bone and giant cell-rich chondroblastomas. Two hundred eighty-one bone lesion samples, including 170 giant cell tumors of the bone, 26 chondroblastomas and 85 other giant cell-rich and/or epiphyseal tumors, were analyzed...

Many options are available in literature for the management of delayed reconstruction following calcanectomy. In cases of low-grade tumor lesions, conservative surgery can be considered. We describe a case of delayed reconstruction by calcaneal allograft after calcanectomy for low-grade chondrosarcoma. At 12-month follow-up, the patient had no pain; MSTS score and AOFAS score were satisfactory. Subtalar nonunion was observed with no secondary displacement or graft necrosis. The aim of conservative treatment for this patient was to restore normal gait with plantigrade locomotion and function of the Achilles tendon...
