RESUMO
Malignant TS-GCT is an extremely rare and aggressive tumor with only few cases published in the literature, due to the small number of cases is not completely understood and is diagnostically challenging. Although surgical treatment is the primary treatment modality, there is no consensus regarding adjuvant treatment. Regardless of mode of treatment, the tumor still caries unfavorable prognosis. In this paper, we reviewed the literature for cases of malignant TS-GCT. We also would like to present an additional case of malignant TS-GCT that was found in an unusual location in subcutaneous tissue of the midthigh.
RESUMO
INTRODUCTION: Macrodystrophia lipomatosa is a rare benign condition characterized by a progressive persistent proliferation of the mesenchymal components and elements, with a disproportionate increase in fibro-adipose tissue. It causes a debilitating functional and psychological effect on the patient and his family. CASE PRESENTATION: A 25-years-old male patient presented complaining of left middle finger swelling which was painless and progressive in size with no restriction of range of motion. Plain X-ray films of the left hand showed a heterogeneous lobulated soft tissue mass on the volar aspect of the middle finger which was confirmed by MRI scan. Surgery was performed by doing a left middle finger soft tissue excision and diagnosis of Macrodystrophia lipomatosa was confirmed by the histopathology report. Patient was on regular follow up in the clinic with no tumour recurrence and an excellent cosmetic as well as functional result with full finger joints range of motion. CONCLUSION: Macrodystrophia lipomatosa should be suspected with this kind of presentations. Combination of the clinical history and examination with the aid of radiological assays aided in the diagnosis of this extremely rare case and led to the appropriate management by excising this mass and restoring the normal function of the patient's hand.
RESUMO
Resection of large lipomatous tumours in the subdeltoid region remains technically challenging due to the risk of injury to the axillary neurovascular bundle. We describe a novel deltoid release and reinsertion technique for resection of large lipomatous tumours of the sub-deltoid region and report the functional and oncologic outcomes of six patients who underwent this procedure. Three cases were diagnosed histologically as atypical lipoma and three cases were diagnosed as lipoma. There was one local recurrence in a case of an atypical lipoma. Rotator cuff function was comparable to that of the contralateral side in all cases and the average Constant Score adopted by the European Shoulder and Elbow Society was 84 (range 81 to 92) out of 100. We conclude that patients with large sub-deltoid lipomatous tumours who undergo resection through a previously undescribed deltoid release and reinsertion technique have excellent functional outcome with a low risk for recurrence.
RESUMO
BACKGROUND: The goal of this study was to determine the oncologic outcomes in localized resectable soft-tissue sarcoma after pre- versus postoperative radiation. METHODS: Literature searches through MEDLINE, EMBASE, CancerLit, and the Cochrane Database were performed with the following search terms: sarcoma, radiation, preoperative, and postoperative. Two reviewers independently assessed all eligible publications with the Detsky Quality Scale for Randomized Trials and the Newcastle-Ottawa Quality Assessment Scale for case-control studies. The primary outcome measure was the pooled odds ratio and 95% confidence intervals (95% CI) for the risk of local recurrence calculated through the fixed- and random-effects methods. Time-dependent survival data were calculated as an average across all studies. RESULTS: Five eligible studies were identified including a total of 1,098 patients. The P value for heterogeneity was 0.259, and the variability (I (2)) in results across studies due to true differences in treatment effect was 25%. The risk for local recurrence was lower in the preoperative group with an odds ratio of 0.61 (95% CI 0.42-0.89) by means of the fixed-effects method, and an odds ratio of 0.67 (95% CI 0.39-1.15) by means of the random-effects method. Average survival was 76% (range 62-88%) in the preoperative group and 67% (range 41-83%) in the post-operative group. CONCLUSIONS: The delay in surgical resection necessary to complete preoperative radiation does not seem to increase the risk of lethal metastatic spread. The risk of local recurrence may be lower after preoperative radiation. These findings must be interpreted with caution because of the heterogeneity and bias in the available studies.
