Primary thyroid teratomas are rare, usually benign, and typically occur in children. We report the unusual occurrence of a malignant thyroid teratoma in a young man. Initial ultrasound and CT studies revealed an 8.5 heterogeneous mass involving the entire right thyroid lobe causing tracheal compression and deviation. Fine‐needle aspiration (FNA) revealed malignant cells with possible neuroendocrine features. Similar findings have been previously reported, with an occasional interpretation as possible medullary thyroid carcinoma. In no report, as with our case, has the correct diagnosis been suggested with FNA. The surgical specimen contained abundant primitive neuroepithelium with a very minor component of mature ectodermal tissue in one area. Like this case, an abundance of immature neuroepithelium has been reported in essentially all previous reports of primary malignant thyroid teratoma, sometimes creating a challenge to find another type of germ cell tissue. Array comparative genomic hybridization studies in this case revealed a markedly complex karyotype including gain of chromosome 12 and loss of 17p. Amplification of MYCN, EWSR1 rearrangement and isochromosome 12p were not identified, providing no evidence for neuroblastoma or Ewing sarcoma/peripheral neuroectodermal tumor, both of which have also rarely been reported as primary thyroid tumors. With the use of cisplatinum‐based chemotherapy combined with radiation, survival times have increased dramatically. Our patient is now disease free and back to his normal activities after relatively short follow‐up. Although rare, it is important to be aware that teratomas may present as a thyroid nodule. Recognition by FNA is challenging, and requires multiple modalities for full identification.
This mass-gathering motorsport event had a moderate number of patients requiring medical attention. The preparedness plan was implemented successfully with minimal impact on EMS resources and local medical facilities. This medical preparedness plan may serve as a model to other cities preparing for an inaugural motorsports event.
It is the aim of our study to determine if the assessment of intraoperative breast cancer margins leads to decreased incidence of repeat operations and decreased cost. We collected data prospectively from two hospitals in Austin, TX, University Medical Center at Brackenridge (UMCB) and Seton Northwest Hospital (SNW), over a 2-year period. Comparison was made to see if intraoperative margin assessment affected total surgical costs and need for reoperation. One hundred and seven cases met criteria for inclusion in the study (UMCB = 45, SNW = 62). Intraoperative margin assessment was used in zero cases at SNW (0%) and in 17 at UMCB (38%). Intraoperative assessment was used in 16 per cent of total cases. Sixty per cent of cases at SNW required subsequent return to the operating room. Twenty-four per cent of cases at UMCB required subsequent reoperation ( P < 0.05). The average number of surgical interventions required was 1 ± 0.3 with intraoperative assessment, 2 ± 0.6 without, ( P < 0.05). Total surgical costs were $15,341 ± $4,328 with intraoperative assessment and $22,013 ± $13,821 without ( P < 0.05). Use of intraoperative margin assessment for breast cancer operations leads to both a decrease in reoperations as well as a decrease in total operative costs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
