Malignant thyroid teratoma: an integrated analysis of case series and case reports

Malignant thyroid teratoma (MTT) is a very rare thyroid malignancy. These neoplasms have been reported only in case reports and small-sized case series so far. In this study, we searched for MTTs in the Surveillance, Epidemiology, and End Result (SEER) program during 1975-2016. Subsequently, we incorporated the SEER data with published MTT cases in the literature to analyze the characteristics and prognostic factors of MTTs. Integrated data were analyzed using Chi-square or Fisher’s exact test for categorical covariates, and t-test or Mann-Whitney test for continuous variables. We included 28 studies with 36 MTT cases and found additional 8 cases from the SEER program for final analyses. Our results showed that MTT is typically seen in adult females. These neoplasms were associated with an aggressive clinical course with high rates of extrathyroidal extension (80%) and nodal involvement (62%). During follow-up, the development of recurrence and metastases were common (42% and 46%, respectively), and one-third of patients died at the last follow-up. Large tumor size (p = 0.022) and the presence of metastases during follow-up (p = 0.008) were associated with a higher mortality rate. In conclusion, our study demonstrated the characteristic features of MTT patients and outlined some parameters associated with a negative outcome which could help clinicians better predict the clinical course of these neoplasms.

Abstract BACKGROUND Synovial sarcoma of the nerve is a rare entity with several cases and case series reported in the literature. Despite an improved understanding of the biology, the clinical course is difficult to predict. OBJECTIVE To compile a series of patients with synovial sarcoma of the peripheral nerve (SSPN) and assess clinical and pathological factors and their contribution to survival and recurrence. METHODS Cases from 2 institutions collected in patients undergoing surgical intervention for SSPN. Systematic review including PubMed and Scopus databases were searched for related articles published from 1970 to December 2018. Eligibility criteria: (1) case reports or case series reporting on SSPN, (2) clinical course and/or pathological features of the tumor reported, and (3) articles published in English. RESULTS From patients treated at our institutions (13) the average follow-up period was 3.2 yr. Tumor recurrence was seen in 4 cases and death in 3. Systematic review of the literature yielded 44 additional cases with an average follow-up period of 3.6 yr. From pooled data, there were 10 recurrences and 7 deaths (20% and 14%, respectively). Adjuvant treatment used in 62.5% of cases. Immunohistochemical markers used in diagnosis varied widely; the most common are the following: Epithelial membrane antigen (EMA), cytokeratin, vimentin, cluster of differentiation (CD34), and transducin-like enhancer of split 1 (TLE1). Statistical analysis illustrated tumor size and use of chemotherapy to be negative predictors of survival. No other factors, clinically or from pathologist review, were correlated with recurrence or survival. CONCLUSION By combining cases from our institution with historical data and performing statistical analysis we show correlation between tumor size and death.

Secondary Hemorrhage

Introduction: Dural artertiovenous fistulae (dAVF) are rare causes of secondary intracranial hemorrhage (ICH) and there remains a paucity of knowledge regarding their natural history. To date our knowledge comes from small case series. CONDOR, (Consortium for Dural Arteriovenous Fistula Outcomes Research), a large multi-institutional retrospective registry, provides a unique opportunity to evaluate the outcomes of patients presenting with dAVF related hemorrhages. Methods: We performed a retrospective review of 1077 dAVF patients from the CONDOR registry and selected those patients who presented with hemorrhage secondary to the dAVF. Patient characteristics, clinical presentation/follow-up, and radiographic details were analyzed for associations with patient outcomes. An outcome of mRS 0-2 was categorized as a “good” outcome and 3-6 as “poor”. Statistics were performed in SAS 9.4 with chi square, fisher’s exact test, and stepwise select variable multivariate analysis; P<.05 was marked as the level for statistical significance. Results: Evaluation of the CONDOR dataset yielded 267 patients who presented with hemorrhage. The mean age of the population was 59 ±13y.o, 30% were female, 40% had a history of smoking and 93% were not on anticoagulants. The median follow-up was 1.4 years. The mortality was 4.0 % at follow-up, and 83% of patients had a good outcome (mRS 0-2). Univariate analysis found age (p=0.001), anticoagulant use (p=0.006), and presentation mRS (p=0.03) were associated with poor outcome at follow-up. Subtype of hemorrhage (parenchymal hemorrhage or subarachnoid hemorrhage), smoking, and cortical venous shunting of the lesion, (i.e. Cognard grade IIb and greater) did not reach statistical significance. On multivariate analysis age (p=0.023) and mRS (p=0.035) at presentation but not anti-coagulant use (p=0.11) was associated with follow-up mRS. Conclusion: Within the largest individual patient series to date, we found that dAVF presenting with hemorrhage was associated with a relatively low risk of mortality. Age and mRS at presentation were most strongly predictive of outcome. Our results suggest that dAVF hemorrhage may be associated with a less morbid outcome than other forms of secondary hemorrhage.

Diagnostic Pitfalls

The combined colonic adenoma/microcarcinoid tumor is a rare intestinal neoplasm featuring intermingled adenomatous and carcinoid components. A few case reports and small case series have suggested that this entity exhibits an indolent clinical course. Here, we report two cases with these tumors, and describe the morphological features and clinical follow-up. A 61-year-old male and 78-year-old male presented with heme-positive stools at their medical checkups. Colonoscopy revealed masses in the colons; we performed endoscopic mucosal resection. Both lesions featured low-grade adenomas and low-grade neuroendocrine tumors. We diagnosed combined colonic adenomas/microcarcinoids. The clinical courses of both patients were benign at follow-up at 2.5 and 6 years. Awareness of this rare colonic tumor should prevent potential diagnostic pitfalls and may help clarify the natural history of these tumors and their possible relationships with composite glandular/carcinoid tumors.

OBJECTIVEThe role of mechanical thrombectomy in pediatric acute ischemic stroke is uncertain, despite extensive evidence of benefit in adults. The existing literature consists of several recent small single-arm cohort studies, as well as multiple prior small case series and case reports. Published reports of pediatric cases have increased markedly since 2015, after the publication of the positive trials in adults. The recent AHA/ASA Scientific Statement on this issue was informed predominantly by pre-2015 case reports and identified several knowledge gaps, including how young a child may undergo thrombectomy. A repeat systematic review and meta-analysis is warranted to help guide therapeutic decisions and address gaps in knowledge.METHODSUsing PRISMA-IPD guidelines, the authors performed a systematic review of the literature from 1999 to April 2019 and individual patient data meta-analysis, with 2 independent reviewers. An additional series of 3 cases in adolescent males from one of the authors’ centers was also included. The primary outcomes were the rate of good long-term (mRS score 0–2 at final follow-up) and short-term (reduction in NIHSS score by ≥ 8 points or NIHSS score 0–1 at up to 24 hours post-thrombectomy) neurological outcomes following mechanical thrombectomy for acute ischemic stroke in patients < 18 years of age. The secondary outcome was the rate of successful angiographic recanalization (mTICI score 2b/3).RESULTSThe authors’ review yielded 113 cases of mechanical thrombectomy in 110 pediatric patients. Although complete follow-up data are not available for all patients, 87 of 96 (90.6%) had good long-term neurological outcomes (mRS score 0–2), 55 of 79 (69.6%) had good short-term neurological outcomes, and 86 of 98 (87.8%) had successful angiographic recanalization (mTICI score 2b/3). Death occurred in 2 patients and symptomatic intracranial hemorrhage in 1 patient. Sixteen published thrombectomy cases were identified in children < 5 years of age.CONCLUSIONSMechanical thrombectomy may be considered for acute ischemic stroke due to large vessel occlusion (ICA terminus, M1, basilar artery) in patients aged 1–18 years (Level C evidence; Class IIb recommendation). The existing evidence base is likely affected by selection and publication bias. A prospective multinational registry is recommended as the next investigative step.

Struma Ovarii

Struma ovarii is a rare variant of the mature ovarian teratoma composed of more than 50% thyroid tissue. Thyroid type carcinoma can occur in 5% of struma ovarii. Given the rarity of this pathology, as well as the different clinical course, approaches to the treatment of this disease are controversial. The proposed approaches to treatment vary from ovarian resection to total hysterectomy with bilateral salpingo-oophorectomy and adjuvant therapy. We present here 6 case reports of thyroid type carcinoma in struma ovarii and outcome of patients treated in our clinic. All patients had pelvic surgery of different extent, followed by thyroidectomy and radioiodine therapy. The incidence of metastasis is 67% (4/6), 2 - intraperitoneal metas-tases, 2 - bone metastases. Among patients with metastases, 2 have reached a complete response, one with a good response continues treatment, one had progression. The follow-up period is 1 to 15 years (median 4 years). One patient with follicular carcinoma died of progression 8 years after diagnosis. The remaining patients are alive.

Abstract Background Human papillomavirus (HPV) type 16 accounts for a larger share of cervical cancer and has been a major health problem worldwide for decades. The progression of initial infection to cervical cancer has been linked to viral sequence properties; however, the role of HPV16 variants in the risk of cervical carcinogenesis, especially with longitudinal follow-up, is not fully understood in China. Methods We aimed to investigate the genetic variability of HPV16 E6 and E7 oncogenes in isolates from cervical exfoliated cells. Between December 2012 and December 2014, a total of 310 single HPV16-positive samples were selected from women living in the Taizhou area, China. Sequences of all E6 and E7 oncogenes were analysed by PCR-sequencing assay. Detailed sequence comparison, genetic heterogeneity analyses and maximum-likelihood phylogenetic tree construction were performed with BioEdit Sequence Alignment Editor and MEGA X software. Data for cytology tests and histological diagnoses were obtained from our Taizhou Area Study with longitudinal follow-up for at least 5 years. The relationship between HPV16 variants and cervical carcinogenesis risk was analysed by the chi-square test or Fisher’s exact test. Results In this study, we obtained 64 distinct variation patterns with the accession GenBank numbers MT681266-MT681329. Phylogenetic analysis revealed that 98.3% of HPV16 variants belong to lineage A, in which the A4 (Asian) sublineage was dominant (64.8%), followed by A2 (12.1%), A1 (11.4%), and A3 (10.0%). The A4 (Asian) sublineage had a higher risk of CIN2+ than the A1–3 (European) sublineages (OR = 2.69, 95% CI = 1.04–6.97, P < 0.05). Furthermore, nucleotide variation in HPV16 E6 T178G is associated with the development of cervical cancer. Conclusion These data could provide novel insights into the role of HPV16 variants in cervical carcinogenesis risk in China.

Background: Patients with hidradenitis suppurativa (HS) are still often disappointed with the current treatments offered and there is a clear demand for more effective options. Since the late 1990s there has been a revival in the use of radiotherapy (RT) for different benign diseases, including HS. During the past 20 years one case series and some scattered case reports have described promising results of RT. Objectives: To evaluate the long-term efficacy of RT in early-stage HS. Methods: A postal survey-based long-term follow-up with simple factual questions of partly retrospective and partly contemporary characteristics was performed. Sixty-four patients (96 axillae), diagnosed with mild to moderate HS were irradiated with a orthovoltage unit with 100 kV, 3 mm Al or 200 kV, 0.5 Cu filtering, respectively. Four to six biweekly fractional doses ranging from 0.75 to 1 Gy up to a total dose of 6 Gy in one series, and in chronic cases followed by four daily fractions of 2 Gy up to a total dose of 14 Gy, were given. Late treatment toxicity and the rate of remission of the disease were evaluated. Results: The overall response rate of the survey was 64.1% with 40.6% (26/64) valid, complete questionnaires. In total, 40 axillae were irradiated in these 26 patients. After a median follow-up of 40 years (range 32–52) complete remission of the lesions occurred in 34 of the 40 sites (85%). None of the 26 patients with 40 irradiated sites reported adverse effects at the time of the survey. Conclusions: RT appears to be an effective treatment for early and mild HS in the majority of patients. In this case series, no side effects were reported after a median follow-up period of 40 years.

We describe the case of a patient with hemolysis-associated Clostridium perfringens septicemia and review all similar cases published in the literature since 1990, with specific focus on the relationship between treatment strategy and survival. We searched PubMed for all published cases of C. perfringens-associated hemolysis, using the medical subject terms “clostridia,” “clostridial sepsis,” and/or “hemolysis.” All case reports, case series, review articles, and other relevant references published in the English literature since 1990 were included in this study. There were no exclusion criteria. Each case was examined with respect to presenting features of illness, antibiotic regimen, time-to-antibiotic therapy, additional interventions, complications, and patient survival. These variables were entered into a data set and then systematically analyzed with the aid of a statistician, using serial t tests and chi-square analyses. Since 1990, 50 patients of C. perfringens septicemia with hemolysis have been reported. Median age was 61 years (range 31-84), and 58% were male. Mortality was 74%, with a median time to death of 9.7 hours (range 0-96 hours). Of the patients, 35 (70%) were treated medically, while 15 (30%) received antibiotics and surgery. Surgical intervention was associated with significantly improved survival (risk ratio [RR] 0.23, 95% confidence interval [CI] 0.10, 0.53) as was the use of a combination of penicillin and clindamycin (RR of death 0.46, 95% CI 0.25, 0.83). Four patients utilizing hyperbaric oxygen therapy (HBOT) have been reported, and all patients survived. In cases of clostridial sepsis with hemolysis, strong predictors of survival include early initiation of appropriate antibiotics as well as surgical removal of infected foci. The HBOT may also be associated with survival. The disease often progresses rapidly to death, so rapid recognition is critical for the patient survival.

Gastrointestinal Neuroendocrine Tumor

Abstract Gastrointestinal neuroendocrine tumor (NET) associated with a metachronous intestinal adenocarcinoma is rare. We report the case of a 71-year-old man with an ileal NET. Patient has previously undergone a left colectomy for sigmoid cancer. We report a complete review both of the metachronous and synchronous NET. A comprehensive systematic literature search in PubMed, EMBASE, and MEDLINE identified a total of 35 relevant studies. This study includes an analysis of review articles, case reports, case series, retrospective studies and population-based studies. In the English literature to date, there are 21 case reports (19 synchronous cases and 2 metachronous cases), 3 case series and 3 review articles, and less than 10 retrospective studies or population-based studies. A total of 31 patients in 24 articles were included in the study: 28 patients with a synchronous gastrointestinal NET and colorectal adenocarcinoma and 3 patients with metachronous gastrointestinal NET and colorectal adenocarcinoma. The incidence of synchronous cancer (particularly for colorectal and gastric cancer) with a gastrointestinal NET ranges from 10 to 50%, while for the metachronous ones it is still unclear. This is the third metachronous case report and the first descriptive case of gastrointestinal NET diagnosed 2 years after a colorectal adenocarcinoma. An endoscopic follow-up program for gastrointestinal NET patients and/or for first-degree relatives of NET patients appears recommendable.

This study aims to assess the risk of severe forms of COVID-19, based on clinical, laboratory, and imaging markers in patients initially admitted to the ward. This is a retrospective observational study, with data from electronic medical records of inpatients, with laboratory confirmation of COVID-19, between March and September 2020, in a hospital from Juiz de Fora-MG, Brazil. Participants (n = 74) were separated into two groups by clinical evolution: those who remained in the ward and those who progressed to the ICU. Mann–Whitney U test was taken for continuous variables and the chi-square test or Fisher’s exact test for categorical variables. Comparing the proposed groups, lower values of lymphocytes ( p = <0.001) and increases in serum creatinine ( p = 0.009), LDH ( p = 0.057), troponin ( p = 0.018), IL-6 ( p = 0.053), complement C4 ( p = 0.040), and CRP ( p = 0.053) showed significant differences or statistical tendency for clinical deterioration. The average age of the groups was 47.9 ± 16.5 and 66.5 ± 7.3 years ( p = 0.001). Hypertension ( p = 0.064), heart disease ( p = 0.048), and COPD ( p = 0.039) were more linked to ICU admission, as well as the presence of tachypnea on admission ( p = 0.051). Ground-glass involvement >25% of the lung parenchyma or pleural effusion on chest CT showed association with evolution to ICU ( p = 0.027), as well as bilateral opacifications ( p = 0.030) when compared to unilateral ones. Laboratory, clinical, and imaging markers may have significant relation with worse outcomes and the need for intensive treatment, being helpful as predictive factors.
