RESUMEN

Objective: This novel pilot study constructs a social deprivation index (SDI) and utilizes an area deprivation index (ADI) to evaluate the link between social determinants of health and rhinology patient experiences. Methods: Adult patients undergoing outpatient care of chronic rhinitis and chronic rhinosinusitis at a tertiary academic medical center were recruited to participate in a telephone survey assessing symptoms, social/emotional consequences of disease, and barriers to care on a 5-point Likert scale. Sociodemographic characteristics were utilized to rate SDI on an 8-point scale. ADI was obtained by area code of residence. Ordered logistic regression was used to examine associations between the SDI/ADI and perceptions of rhinology care. Results: Fifty patients were included. Individuals with higher SDI scores (i.e., more socially deprived) experienced more severe nasal congestion (p = .007). Furthermore, higher national ADI correlated with increased severity of smell changes (p = .050) and facial pressure (p = .067). No association was seen between either deprivation index and global/psychiatric symptoms. While no correlations were found between higher SDI and difficulties with the costs of prescriptions, rhinologist's visits, or saline, higher SDI was correlated with decreased difficulty with surgery costs (p = .029), and individuals with higher national ADI percentile had increased difficulties obtaining nasal saline (p = .029). Conclusion: Worse social deprivation is associated with difficulties obtaining saline rinses and increased severity of nasal/sinus symptoms in an urban, underserved, majority-Black population. These findings suggest social factors affect access to and quality of rhinology care in a complex and nuanced way and highlight the need for a specific SDI to further study social determinants of health in rhinology. Level of Evidence: 2c.

RESUMEN

BACKGROUND: Genetic research in nonsyndromic craniosynostosis remains limited compared with syndromic craniosynostosis. This systematic review aimed to comprehensively summarize the genetic literature of nonsyndromic craniosynostosis and highlight key signaling pathways. METHODS: The authors performed a systematic literature search of PubMed, Ovid, and Google Scholar databases from inception until December of 2021 using search terms related to nonsyndromic craniosynostosis and genetics. Two reviewers screened titles and abstract for relevance, and three reviewers independently extracted study characteristics and genetic data. Gene networks were constructed using Search Tool for Retrieval of Interacting Genes/Proteins (version 11) analysis. RESULTS: Thirty-three articles published between 2001 and 2020 met inclusion criteria. Studies were further classified into candidate gene screening and variant identification studies ( n = 16), genetic expression studies ( n = 13), and common and rare variant association studies ( n = 4). Most studies were good quality. Using our curated list of 116 genes extracted from the studies, two main networks were constructed. CONCLUSIONS: This systematic review concerns the genetics of nonsyndromic craniosynostosis, with network construction revealing TGF-ß/BMP, Wnt, and NF-κB/RANKL as important signaling pathways. Future studies should focus on rare rather than common variants to examine the missing heritability in this defect and, going forward, adopt a standard definition.

RESUMEN

Background: To describe a novel technique to modify the proportional length of the anterior-to-posterior digastric muscles to improve neck aesthetics. Objective: To provide an objective measure to quantify neck rejuvenation and a novel technique to adjust the digastric ratio. Design: We retrospectively compared 52 patients who had neck rejuvenation with or without digastric manipulation. Preoperative and postoperative images were analyzed and compared with computer software using a novel analysis technique to measure the digastric ratio and neck height. Distances between the menton, cervical point (CP), and gonion were measured. Results: The anterior-to-posterior digastric ratio improved an average of 26.5% (p < 0.01) in the new technique group, 15.9% in the control group. Distance of the CP to the inferior edge of the mandible decreased an average of 13.9% using the new technique. Conclusion: The ratio of anterior-to-posterior digastric muscle appears to improve as well as the neck height with manipulation of the digastric muscles.

RESUMEN

Objectives: To quantify the current proportion of women in otolaryngology at different levels of professorship and determine whether these proportions differ by US region. Methods: Academic rank and gender at all ACGME-accredited otolaryngology programs in the United States were determined from departmental websites, Doximity, and LinkedIn from November 2021 to March 2022. Individuals were then further organized using US Census Bureau-designated regions. Results: Among the 2682 faculty positions at 124 ACGME-accredited programs, women held 706 (26.3%) of these positions. Female representation was highest at the assistant professorship level, with women holding 286 (37.2%) positions out of a total 769. At the associate professorship level, women held 141 (27.6%) of the 511 total positions. The largest gender disparity is seen at the full professorship level; only 69 (13.6%) positions out of 508 were held by women. Out of every region and rank, only assistant professorship in the West had no significant difference in percentages of men and women (p = .710). Female representation of professors in the Northeast was significantly lower than that of our reference group (the South; ß = -10.9, p = .020). Conclusions: Otolaryngology has exhibited great progress in increasing female representation, with assistant professorship in the West reaching gender parity. However, the gender gap at other faculty levels still leaves much to be desired, particularly in senior ranks. The lack of otolaryngologists at senior ranks is detrimental to mentorship of junior faculty, residents, and medical students. Renewed efforts should be made to decrease the gender disparity in the South, Northeast, and particularly at the professorship level.

RESUMEN

OBJECTIVES: Health-related quality of life has been well studied across transplantation fields, but factors associated with lung transplant preoperative and postoperative quality of life remain unknown. Here, we determine factors associated with health-related quality of life in lung transplant candidates and recipients to identify patients at risk of lower health-related quality of life. MATERIALS AND METHODS: From January 2021 to May 2022, health-related quality of life was measured in candidates and recipients using the RAND 36-Item Short Form Health Survey questionnaire. We reviewed demographic parameters and clinical information and scored frailty according to the modified 5-item frailty index. We performed Fisher exact test and the Pearson chi-square test and used linear regression models to determine covariate associations on physical component summary, mental component summary, and self-reported health scores (α = 0.05). RESULTS: Eleven candidates and 17 recipients comp-leted the survey. Compared with candidates, transplant recipients reported significantly higher scores in 4 of the 8 health domains and in the physical component summary (P < .01), mental component summary (P = .05), and self-reported health score (P < .01). In candidates, higher body mass index and higher modified 5-item frailty index scores were negatively associated with the physical component summary and mental component summary, respec-tively (P < .05). In recipients, higher body mass index and higher lung allocation scores were associated with lower values for the physical component summary (-2.29; P < .05) and self-reported health score (-0.33; P < .05), respectively. CONCLUSIONS: Body mass index, the modified 5-item frailty index, and the lung allocation score were significantly associated with health-related quality of life in lung transplant recipients. Future interventions should target these modifiable associations to maximize candidate and recipient health-related quality of life.

RESUMEN

Introduction: There is a lack of qualitative analysis of the personal experiences within Couples Matching. In this qualitative study, we aim to record personal attitudes, reflections, and advice on experiences with the Couples Match process. Methods: Our survey, consisting of two open-ended questions regarding the experience of Couples Matching, was distributed from January 2022 to March 2022 via email to 106 otolaryngology program directors across the nation. Survey responses were analyzed iteratively using the constructivist grounded theory to construct themes related to pre-match priorities, match-related stressors, and post-match satisfaction. Themes were developed inductively and refined iteratively as the dataset evolved. Results: 18 Couples Match residents responded. In response to the first question: "What was the most difficult part of the process for you and/or your partner?", we identified the following themes: cost and financial burden, increased stress on the relationship, sacrificing top choices, and finalizing the match list. In response to the second question: "Using your experience as a previous applicant, what advice would you give to another couple planning on couples matching?", we identified four common themes: compromise, advocacy, dynamic conversations, and applying broadly. Conclusion: We sought to understand the Couples Match process through the perspective of previous applicants. Analyzing the views and attitudes of Couples Match applicants, our study captures the most challenging aspects of the experience and highlights possible areas to improve advising for couples, including important factors to consider when applying, ranking, and interviewing.

RESUMEN

Objectives Insurance coverage plays a critical role in head and neck cancer care. This retrospective study examines how insurance coverage affects nasopharyngeal carcinoma (NPC) survival in the United States using the Surveillance, Epidemiology, and End Results (SEER) program database. Design, Setting, and Participants A total of 2,278 patients aged 20 to 64 years according to the International Classification of Diseases for Oncology (ICD-O) codes C11.0-C11.9 and ICD-O histology codes 8070-8078 and 8080-8083 between 2007 and 2016 were included and grouped into privately insured, Medicaid, and uninsured groups. Log-rank test and multivariable Cox's proportional hazard model were performed. Main Outcome Measures Tumor stage, age, sex, race, marital status, disease stage, year of diagnosis, median household county income, and disease-specific survival outcomes including cause of death were analyzed. Results Across all tumor stages, privately insured patients had a 59.0% lower mortality risk than uninsured patients (hazard ratio [HR]: 0.410, 95% confidence interval [CI]: [0.320, 0.526], p < 0.01). Medicaid patients were also estimated to have 19.0% lower mortality than uninsured patients (HR: 0.810, 95% CI: [0.626, 1.048], p = 0.108). Privately insured patients with regional and distant NPC had significantly better survival outcomes compared with uninsured individuals. Localized tumors did not show any association between survival and type of insurance coverage. Conclusion Privately insured individuals had significantly better survival outcomes than uninsured or Medicaid patients, a trend that was preserved after accounting for tumor grade, demographic and clinicopathologic factors. These results underscore the difference in survival outcomes when comparing privately insured to Medicaid/uninsured populations and warrant further investigation in efforts for health care reform.

RESUMEN

OBJECTIVE: To examine the oral microbiome in the context of oral cavity squamous cell carcinoma. STUDY DESIGN: Basic science research. SETTING: Academic medical center. METHODS: Oral swabs were collected from patients presenting to the operating room for management of oral cavity squamous cell carcinoma and from age- and sex-matched control patients receiving surgery for unrelated benign conditions. 16S ribosomal RNA (rRNA) sequencing was performed on genetic material obtained from swabs. A bacterial rRNA gene library was created and sequence reads were sorted into taxonomic units. RESULTS: Thirty-one control patients (17 males) and 35 cancer patients (21 males) were enrolled. Ages ranged from 23 to 89 (median 63) for control patients and 35 to 86 (median 66) for cancer patients. Sixty-one percent of control patients and 63% of cancer patients were smokers. 16S analyses demonstrated a significant decrease in Streptococcus genera in oral cancer patients (34.11% vs 21.74% of the population, p = .04). Increases in Fusobacterium, Peptostreptococcus, Parvimonas, and Neisseria were also found. The abundance of these bacteria correlated with tumor T-stage. CONCLUSION: 16S rRNA sequencing demonstrated changes in bacterial populations in oral cavity cancer and its progression compared to noncancer controls. We found increases in bacteria genera that correspond with tumor stage-Fusobacteria, Peptostreptococcus, Parvimonas, Neisseria, and Treponema. These data suggest that oral cancer creates an environment to facilitate foreign bacterial growth, rather than implicating a specific bacterial species in carcinogenesis. These bacteria can be employed as a potential marker for tumor progression or interrogated to better characterize the tumor microenvironment.

RESUMEN

Background: Pasteurella multocida, is a bacterium that is frequently transmitted to humans from domestic pets. Infections are generally localized, but previous reports have exhibited that Pasteurella can cause systemic infections such as peritonitis, bacteremia and in some rare cases tubo-ovarian abscess. Case presentation: We present a case of a 46-year-old woman who came to the emergency department (ED) with complaints of pelvic pain, abnormal uterine bleeding (AUB), and fever. A non-contrast computed tomography (CT) of abdomen and pelvis showed uterine fibroids with sclerotic changes in lumbar vertebrae and pelvic bones causing a high degree of suspicion for cancer. On admission, blood culture, complete blood count (CBC) and tumor markers were drawn. Additionally, an endometrial biopsy was performed to rule out the possibility of endometrial cancer (EC). The patient underwent an exploratory laparoscopy with hysterectomy and bilateral salpingectomy. After diagnosis with P. multocida the patient was treated with five days of Meropenem. Conclusion: There are few cases of P. multocida peritonitis reported; in addition, findings of AUB with sclerotic bony changes in a middle-aged woman is often associated with EC. Thus, clinical suspicion from patient history, infectious disease work-up and diagnostic laparoscopy are essential for proper diagnosis and management.

RESUMEN

OBJECTIVE: To compare outcomes of juvenile nasopharyngeal angiofibroma (JNA) resection between embolized and non-embolized cohorts, and between transarterial embolization (TAE) and direct puncture embolization (DPE). DATA SOURCES: Per PRISMA guidelines, PubMed, Embase, Web of Science, Scopus, and Cochrane databases were searched for publications prior to or in 2021. MATERIALS AND METHODS: Original English manuscripts investigating the resection of JNA with and without preoperative embolization were included. Embolization type, recurrence rate, complication rates, blood loss, and transfusions were extracted. Risk of bias was assessed by the Risk of Bias in Non-randomized Studies-of Interventions method. RESULTS: There were 61 studies with 917 patients included. Preoperative embolization was performed in 79.3% of patients. Of those embolized, 75.8% (N = 551) underwent TAE and 15.8% (N = 115) underwent DPE. JNA recurrence in embolized patients was lower than in non-embolized patients (9.3% vs. 14.4%; odds ratio [OR]: 0.61, 95% confidence interval [CI]: 0.35, 1.06). DPE resulted in lower rates of disease recurrence (0% vs. 9.5%; OR: 0.066, 95% CI: 0.016, 0.272) and complications (1.8% vs. 21.9%; OR: 0.07, 95% CI: 0.02, 0.3) than TAE. A random effects Bayesian model was performed to analyze the difference in mean blood loss in 6 studies that included both embolized and non-embolized patients. This analysis showed a mean reduction in blood loss of 798 mL in the embolized group. CONCLUSIONS: We found embolization decreases blood loss in JNA resection. DPE led to improved recurrence and complication rates when compared to TAE, but future prospective studies are needed to further evaluate which embolization technique can optimize outcomes in JNA. LEVEL OF EVIDENCE: NA Laryngoscope, 133:1529-1539, 2023.

RESUMEN

BACKGROUND: Thrombocytopenia is an abnormally low level of blood platelets (less than 150,000/mL) resulting in an increased risk for bleeding. Typically, patients with platelet levels below 50,000/mL should delay arthroplasty or be transfused with platelets before surgery. However, existing studies are mixed regarding the effects of more moderate thrombocytopenia in terms of total knee and hip arthroplasty outcomes. METHODS: This level III retrospective chart review examined the effects of different severities of preoperative thrombocytopenia on length of hospitalization, readmission, and transfusion rates in 5,617 primary total knee and hip arthroplasties at one tertiary academic medical center. Preoperative platelet levels were sectioned into clinically relevant groups and compared with clinical outcomes using univariable and multivariable models. RESULTS: On univariate analysis, having platelet levels of <100,000/mL and 100 to 149,000/mL was associated with a longer length of stay. However, after controlling individual demographics, there was no association between platelet levels and length of stay, nor with 30-day readmission. Finally, on univariate analysis, patients with platelet levels of <100,000/mL and 100 to 149,000/mL were more likely to have a blood transfusion, which remained true for those with <100,000/mL after controlling for individual demographics. CONCLUSIONS: Total hip and total knee arthroplasty are safe in patients with varying platelet levels and not associated with increased length of stay or 30-day readmission. However, patients with more severe thrombocytopenia are more likely to receive red blood cell transfusions than patients with milder thrombocytopenia.

RESUMEN

OBJECTIVES: Histoplasma capsulatum is a prevalent dimorphic fungus, reaching an exposure rate of 90% in endemic areas such as the Midwest and Central United States. We report an unusual presentation of dysphonia due to right vocal cord paralysis caused by mediastinal lymphadenopathy from histoplasmosis. METHODS: A 73-year-old male presented to an otolaryngology clinic with 4 months of hoarseness. Flexible strobolaryngoscopy demonstrated right vocal cord paralysis in lateral position and a full length glottic gap. Computerized tomography (CT) scan showed enlargement of a right paratracheal node. RESULTS: A lymph node biopsy was obtained and showed histoplasmosis. He was treated with a 3-month course of pozaconazole. He then received a vocal cord medialization injection 2 months after symptom onset, which produced favorable improvement of his symptoms at 8-month follow up. CONCLUSIONS: One other case report in the literature has reported left vocal cord paralysis related to histoplasmosis. This first case of right vocal cord paralysis was extremely unusual and is not often included in the differential diagnosis of vocal cord paralysis.

RESUMEN

Little attention has been paid to olfactory changes during pregnancy with contemporary studies limited in number and sample size. We examined whether pregnancy is associated with differences in olfactory performance and if there were any specific gestational ages at which these differences occur through a comprehensive systematic review and meta-analysis of the current literature. An initial electronic database search identified 234 citations, which were screened at the abstract level. Twenty-three citations were germane for full-text review, and 13 met criteria for inclusion. Our review assessed 5 olfactory measures of interest: odor identification (n = 11 articles), threshold (n = 8), discrimination (n = 5), hedonics (n = 6), and intensity (n = 5). Nine of these 13 studies contained sufficient data for meta-analysis, and these studies included a total of 523 pregnant women and 365 non-pregnant controls. Despite previous subjective and objective reports of odor intolerances and odor hypersensitivity, we did not find any significant differences between pregnant and non-pregnant women in odor discrimination, thresholds, or hedonics. However, meta-analysis of 506 cases and 333 controls showed worse odor identification in pregnant women compared to controls in a random-effects model. Thus, we demonstrate worse performance at odor identification during pregnancy. In this review, we discuss the current evidence (and lack thereof) regarding olfaction in pregnancy as well as highlight current knowledge gaps in this field.

RESUMEN

INTRODUCTION: Actinomycosis is a granulomatous infection that rarely involves the larynx or pharynx. Three cases of actinomycosis of the larynx or pharynx from our institution were reviewed and a systematic literature review was performed to better define surgical management, antibiotic therapy, risk factors, and incidence of recurrence or complications. MATERIALS AND METHODS: PubMed/Medline, Cochrane, Embase, and Google Scholar were searched on November 30, 2021 using the terms "laryngeal actinomycosis", "pharyngeal actinomycosis", "actinomycosis AND larynx", and "actinomycosis AND pharynx." Articles which did not describe appropriate sites or were non-English were excluded. Results were collected for demographic information, site(s) of infection, comorbidities, lesion characteristics and treatments. RESULTS: Along with three cases reported from our institution, 40 unique cases were reviewed from 37 studies for a total of 43 patients (Table 1). 34 (81.0 %) of the patients were male with the highest incidence of infection in the seventh decade (54.8 %). The most common site for the infection was the larynx (69.0 %) followed by the pharynx (16.7 %). Risk factors included a history of radiation therapy, immunosuppression, inhalational irritant, and diabetes (Table 3). The duration of antibiotic therapy varied greatly, from one month to one year and total follow up ranged from 1 month to 2.5 years (Table 1). CONCLUSIONS: A comprehensive review of the literature on pharyngolaryngeal actinomycosis shows that this infection has increased prevalence within the head and neck cancer patient population. Similar to cervicofacial actinomycosis, these atypical sites have shown favorable responses to extended antibiotic therapy and generally do not require aggressive surgical management.

RESUMEN

Ovarian tissue cryopreservation (OTC) is the only pre-treatment option currently available to preserve fertility for prepubescent girls and patients who cannot undergo ovarian stimulation. Currently, there is no standardized method of processing ovarian tissue for cryopreservation, despite evidence that fragmentation of ovaries may trigger primordial follicle activation. Because fragmentation may influence ovarian transplant function, the purpose of this systematic review was (1) to identify the processing sizes and dimensions of ovarian tissue within sites around the world, and (2) to examine the reported outcomes of ovarian tissue transplantation including, reported duration of hormone restoration, pregnancy, and live birth. A total of 2,252 abstracts were screened against the inclusion criteria. In this systematic review, 103 studies were included for analysis of tissue processing size and 21 studies were included for analysis of ovarian transplantation outcomes. Only studies where ovarian tissue was cryopreserved (via slow freezing or vitrification) and transplanted orthotopically were included in the review. The size of cryopreserved ovarian tissue was categorized based on dimensions into strips, squares, and fragments. Of the 103 studies, 58 fertility preservation sites were identified that processed ovarian tissue into strips (62%), squares (25.8%), or fragments (31%). Ovarian tissue transplantation was performed in 92 participants that had ovarian tissue cryopreserved into strips (n = 51), squares (n = 37), and fragments (n = 4). All participants had ovarian tissue cryopreserved by slow freezing. The pregnancy rate was 81.3%, 45.5%, 66.7% in the strips, squares, fragment groups, respectively. The live birth rate was 56.3%, 18.2%, 66.7% in the strips, squares, fragment groups, respectively. The mean time from ovarian tissue transplantation to ovarian hormone restoration was 3.88 months, 3.56 months, and 3 months in the strips, squares, and fragments groups, respectively. There was no significant difference between the time of ovarian function' restoration and the size of ovarian tissue. Transplantation of ovarian tissue, regardless of its processing dimensions, restores ovarian hormone activity in the participants that were reported in the literature. More detailed information about the tissue processing size and outcomes post-transplant are required to identify a preferred or more successful processing method.

RESUMEN

OBJECTIVES: Parathyroid cysts are rare benign lesions of the head and neck that account for less than 1% of cystic neck masses. We present a rare case of a large 6 cm substernal parathyroid cyst. PRESENTATION OF CASE: An otherwise healthy 65 year-old female presented to the otolaryngology clinic for evaluation of an anterior, midline neck mass. On physical exam, she was noted to have a fullness in the anterior neck extending to the sternal notch. CT demonstrated an enlarged thyroid with a cyst extending to the aortic arch. Initial evaluation suggested a bilateral goiter with substernal extension. The cyst was managed with drainage and observation. After two years of continued growth, the patient underwent a left thyroid lobectomy and mediastinal mass resection via the cervical approach. Final pathology was consistent with a parathyroid cyst. CONCLUSIONS: Parathyroid cysts are a rare cause of neck mass in an adult, and a 6 cm substernal parathyroid cyst represents an unusual site and size for these cysts. Parathyroid cysts are not often considered on the differential of neck and mediastinal cystic lesions. However, appropriate steps should be taken to ensure a proper diagnosis for any cystic lesion in the neck.

RESUMEN

BACKGROUND: Ex vivo lung perfusion (EVLP) is used to assess and preserve lungs prior to transplantation. However, its inherent immunomodulatory effects are not completely understood. We examine perfusate and tissue compartments to determine the change in immune cell composition in human lungs maintained on EVLP. METHODS: Six human lungs unsuitable for transplantation underwent EVLP. Tissue and perfusate samples were obtained during cold storage and at 1-, 3- and 6-h during perfusion. Flow cytometry, immunohistochemistry, and bead-based immunoassays were used to measure leukocyte composition and cytokines. Mean values between baseline and time points were compared by Student's t test. RESULTS: During the 1st hour of perfusion, perfusate neutrophils increased (+22.2 ± 13.5%, p < 0.05), monocytes decreased (-77.5 ± 8.6%, p < 0.01) and NK cells decreased (-61.5 ± 22.6%, p < 0.01) compared to cold storage. In contrast, tissue neutrophils decreased (-22.1 ± 12.2%, p < 0.05) with no change in monocytes and NK cells. By 6 h, perfusate neutrophils, NK cells, and tissue neutrophils were similar to baseline. Perfusate monocytes remained decreased, while tissue monocytes remained unchanged. There was no significant change in B cells or T cell subsets. Pro-inflammatory cytokines (IL-1b, G-CSF, IFN-gamma, CXCL2, CXCL1 granzyme A, and granzyme B) and lymphocyte activating cytokines (IL-2, IL-4, IL-6, IL-8) increased during perfusion. CONCLUSIONS: Early mobilization of innate immune cells occurs in both perfusate and tissue compartments during EVLP, with neutrophils and NK cells returning to baseline and monocytes remaining depleted after 6 h. The immunomodulatory effect of EVLP may provide a therapeutic window to decrease the immunogenicity of lungs prior to transplantation.

RESUMEN

Since the founding of the National Archives (1934) and the Society of American Archivists (1936), archival scholars, educators, and practitioners have discussed and debated the challenges of and future directions for graduate archival education. This exploratory qualitative case study uses semistructured interviews with 33 tenure-track and tenured faculty members from North American graduate archival programs to explore the most pressing issues facing archival education in the twenty-first century. Showing both continuity and change, findings extend and enrich the literature regarding faculty, curriculum, interdisciplinarity and collaboration, DEI, technology, and sustainability.

RESUMEN

INTRODUCTION: Granular cell tumors (GCT) are rare tumors that most frequently present in the oral cavity. While some present within the gastrointestinal tract, a GCT near the trachea is an extremely rare occurence. PRESENTATION OF CASE: A 42-year-old man presented to the Emergency Department after a motor vehicle accident. A computerized tomography (CT) scan revealed an incidental soft tissue 3.2 × 5.5 cm mass anterior to the esophagus and posterior to the trachea with no adjacent lymphadenopathy. The patient denied dyspnea, voice changes, or dysphagia. Due to its size and location, the patient underwent a transcervical excision of the retrotracheal tumor. Tumor cells were positive for CD68, CD163, S100, and SOX10, confirming a GCT. CONCLUSION: This is a distinctive presentation of a large (5 cm) GCT in the plane between the trachea and esophagus. GCTs are not often on the differential diagnosis of masses that present in this region.
