In conclusion, primary sarcomas of the larynx a re rare but tend to present with early symptoms. This likely allows for earlier detection and intervention as compared to their counterparts in other deep soft tissue locations. Pathologically, it is important, although difficult in some cases, to distinguish these neoplasms from sarcomatoid carcino ma and reactive processes. Careful morphologic and immunohistochemical evaluation, as well as correlation with the clinical and radiologic findings, is important for accurate tumor classification.
We report a case of a 53-year-old lady who was incidentally diagnosed to have giant anterior mediastinal mass while undergoing preoperative evaluation for another surgery. She came for surgery after 2 years when she became symptomatic. A large 6.7-lb (2800 g) tumor occupying both hemithoraces and engulfing heart was excised in its entirety through a clamshell thoracotomy under cardiopulmonary bypass standby. Histopathology revealed the final diagnosis as well as differentiated liposarcoma. She is now able to walk 2 km without any symptoms at the end of a 24-month follow-up.
AbstractDedifferentiated liposarcoma (DDLPS) is a rare type of neoplasm which can originally rise in cardiac chamber. Owing to the recurrence and distant metastasis, the prognosis of the primary malignant cardiac tumor is extremely poor and remains a challenge for cardiac surgeons. Here, we report a patient with an intracavitary mass which was diagnosed as DDLPS by postoperative pathological examinations, experienced repeated in ‐situ recurrence of the malignant cardiac tumor.
ConclusionsThe undifferentiated myxoid lipoblastoma is a very rare tumor in infant. Histologically, prominent myxoid change, a plexiform vascular pattern and lacking of mature adipocytes make it indistinguishable from myxoid liposarcoma, PMMTI and aggressive angiomyxoma. The S-100 positive lipoblasts and genetic rearrangement of PLAG1 helps in confirming the diagnosis. Even if there were no mature adipocytes, myxoid lipoblastoma was still a diagnosis that can not be ignored in myxoid tumors in children.
CONCLUSION: Radiomics is a promising, non-invasive method for differentiating between WDLPS and lipoma, outperforming the scores of the radiologists. Further optimization and validation is needed before introduction into clinical practice. PMID: 31747074 [PubMed - in process]
mes L. Chen Soft tissue sarcomas (STS) are diverse tumors with heterogenous alterations. Platforms to detect circulating tumor DNA (ctDNA) have rapidly increased in popularity as they may avoid invasive biopsy morbidity. However, ctDNA profiling concordance with standard solid tumor comprehensive genomic profiling (CGP) is poorly characterized. Here, we report the outcomes of a single-institution experience comparing mutational results from commercial ctDNA and solid tumor CGP in advanced STS subjects. We identified STS subjects who had undergone solid tumor based CGP in four distinct cohorts: Dedifferentiated liposarc...
We present a case of advanced type 1 papillary sarcomatoid renal cell carcinoma infiltrating adjacent organs and showing positivity for MDM2 by immunohistochemistry andMDM2 amplification by fluorescence in situ hybridization. This finding, together with sarcomatoid morphology, poses a potential pitfall for diagnosis with dedifferentiated liposarcoma. MDM2 is known to be altered in various human sarcomas. Only recently, MDM2 alterations have been reported in carcinomas. The presented case illustrates the need of thorough sampling with clinic-pathological correlation before making a final diagnosis in sarcomatoid retroperito...
Publication date: Available online 10 November 2019Source: Seminars in Cancer BiologyAuthor(s): Jessica Burns, Christopher P Wilding, Robin L Jones, Paul H HuangAbstractSarcomas are a rare group of mesenchymal cancers comprising over 70 different histological subtypes. For the majority of these diseases, the molecular understanding of the basis of their initiation and progression remains unclear. As such, limited clinical progress in prognosis or therapeutic regimens have been made over the past few decades. Proteomics techniques are being increasingly utilised in the field of sarcoma research. Proteomic research efforts h...
CONCLUSIONS: Currently, there is no evidence-based recommendation available regarding the management of lipomas detected during open or laparoscopic inguinal hernia surgery. Due to the extremely low risk of the presence of a liposarcoma routine histologic examination cannot be recommended unless the diameter exceeds 10 cm.

ConclusionMedicine cannot provide much care for these advanced cases of multicentric liposarcoma so far. Therefore, more research should be conducted to improve the ability to manage these entities and to identify potential novel therapies.
