Recovery from Covid-19 smell loss: Two-years of follow up.

OBJECTIVE: To report long-term patterns of recovery and non-recovery in a large nationwide cohort of subjects with COVID-19 associated smell loss. STUDY DESIGN: Prospectively, longitudinal questionnaires. SETTING: Web-based national survey. METHODS: A longitudinal survey of adults with COVID-19 and/or sudden change in smell or taste since January 1, 2020 was launched April 10, 2020. Participants were queried again in late May 2022 regarding recovery. Data from respondents with >2 years since loss were analyzed and compared to recovery status of those more recently effected. RESULTS: 1103 responded to the survey of whom 946 met inclusion criteria. Among the 267 respondents for whom at least 2 years of follow up was available, 38.2 % reported full recovery, 54.3 % partial, and 7.5 % no recovery. For the entire cohort (all with ≥3 months since smell loss), 38.7 % reported complete recovery, 51.0 % reported partial recovery (ranging from mild complaints to severe phantosmia or dysosmia), and 10.3 % reported no improvement at all. Complete recovery of smell function was significantly higher in those under 40 years old (45.6 % compared to 32.9 % in those over 40). CONCLUSION: Although the vast majority of subjects who do recover do so within the first 3 months, long-term spontaneous recovery can occur. Rates of recovery do not seem to differ depending on when during the pandemic the loss first occurred.

Predictors of smell recovery in a nationwide prospective cohort of patients with COVID-19.

OBJECTIVE: To determine which factors (demographic, symptoms, comorbidities, and treatments) are associated with recovery of smell in patients with COVID-19 associated olfactory loss. STUDY DESIGN: Prospective, longitudinal questionnaires. SETTING: National survey. METHODS: A longitudinal web-based nationwide survey of adults with COVID-19 associated smell and taste loss was launched April 10, 2020. After completing an initial entry survey, participants received detailed follow-up questionnaires 14 days, and 1, 3 and 6 months later. RESULTS: As of June 25, 2021, 798 participants met study inclusion criteria and completed 6-month questionnaires. Of demographic characteristics only age <40 years was positively associated with smell recovery (p < .003). Of symptoms, difficulty breathing was negatively associated with smell recovery (p < .004), and nasal congestion positively associated with smell recovery (p < .03). Of pre-existing comorbidities only previous head injury (p < .017) was negatively associated with smell recovery. None of the queried medications used to treat COVID were associated with better rates of smell recovery. CONCLUSIONS: Age <40 and presence of nasal congestion at time of COVID-19 infection were predictive of improved rates of smell recovery, while difficulty breathing at time of COVID-19 infection, and prior head trauma predicted worsened rates of recovery. Further study will be required to identify potential mechanisms for the other observed associations. Such information can be used by clinicians to counsel patients suffering COVID-19 associated smell loss as to prognosis for recovery.

Quality of life and safety impact of COVID-19 associated smell and taste disturbances.

OBJECTIVE: The association between COVID-19 and chemosensory loss has garnered substantial attention, however to date little is known about the real-life consequences of impairment in this unique patient population. The aim of this study is to evaluate the quality of life (QOL) and personal safety deficits experienced by patients with COVID-19 infection. STUDY DESIGN: Prospective, longitudinal questionnaires. SETTING: National survey. METHODS: A longitudinal web-based nationwide survey of adults with COVID-19 and/or a sudden change in smell and taste was launched April 10, 2020. Previously published questions on chemosensory-related QOL and safety events were asked at the 6-month follow-up survey. RESULTS: As of February 10, 2021, 480 eligible respondents took the 6-month questionnaire, of whom 322 were COVID-19 positive. Impact on QOL was substantial with 96% of subjects reporting at least one of the defined deficits, and over 75% reporting at least 3 of these. "Reduced enjoyment of food" was the most common complaint (87%), while 43% of subjects self-reported depression. The prevalence of safety-related issues was common in this population, with over 57% reporting at least one, and 36% reporting 2 or more events. Of the events asked, the inability to smell smoke that others could perceive was the most common at 45%. CONCLUSIONS: COVID-19 associated chemosensory losses have a real and substantial impact on both quality of life and safety, beyond mere inconvenience. The high prevalence of these issues despite a relatively short period of olfactory deficit should alert clinicians to the serious risks to an already vulnerable patient population.

Subjective smell and taste changes during the COVID-19 pandemic: Short term recovery.

Since the COVID-19 pandemic began, many individuals have reported acute loss of smell and taste. In order to better characterize all patients with these symptoms, a longitudinal national survey was created. Since April 10, 2020, 549 completed the initial survey, with 295 completing 14-day, and 202 completing 1-month follow up surveys. At 1-month follow-up, 71.8% reported a return to "very good" or "good" smell, and 84.2% reported a return to "very good" or "good" taste. Chemosensory changes are a cardinal sign of COVID-19. Fortunately, our data, representing a large longitudinal study of patients experiencing smell and taste losses during the COVID-19 pandemic, indicates that the majority appear to recover within a month.

COVID-19-related chemosensory changes: Findings from a prospective national database.

Objective: The aim of this study was to review findings from a large prospective national database of chemosensory disturbances associated with coronavirus disease 2019 (COVID-19) infection. Data Sources: The Virginia Commonwealth University Smell and Taste Center national database of COVID-19 chemosensory disturbances. Methods: A series of online surveys, first opened on April 10, 2020, was made accessible nationwide to any adult with sudden chemosensory dysfunction since January 2020. Participants received subsequent follow-up surveys 14 days, 1 month, 3 months, and 6 months after enrollment. An additional survey was sent to all participants on May 28, 2022 to assess long-term outcomes. Information pertaining to demographics, symptoms, comorbidities, treatments, and life impact was collected. Results: Of 363 participants who reported complete smell recovery, 51.2% recovered within 1 month, 70% within 3 months, and 79% within 6 months, while 8.8% took over 1 year to completely recover. Among all participants, 7.5% had no smell recovery. Positive predictors of recovery included age <40, male gender, and the presence of nasal congestion. Negative predictors included difficulty breathing and prior head injury. Many participants reported a decrease in quality of life and the presence of potential safety hazards associated with decreased smell loss. Conclusions: Most subjects with COVID-19-related chemosensory dysfunction recover, with the majority noting complete recovery within weeks of infection. Those aged over 40 years and female gender were associated with lower rates of recovery. A considerable number of participants reported significant impact on quality of life and safety.

Decreasing Incidence of Chemosensory Changes by COVID-19 Variant.

Anecdotal clinical observation suggests that rates of chemosensory dysfunction associated with COVID-19 infection may be decreasing. To investigate, the National COVID Cohort Collaborative database was queried for all patients with and without smell and taste loss within 2 weeks of COVID-19 diagnosis. Six-week periods of peak variant prevalence were selected by using CoVariants.org for analysis. Of 3,678,214 patients with COVID-19 in the database, 616,318 met inclusion criteria during the time intervals of interest, with 3431 having an associated smell or taste disturbance diagnosis. With the initial/untyped variant set as the baseline, the odds ratios for alpha, delta, and omicron (December 27, 2021-February 7, 2022) were 0.50 (95% CI, 0.45-0.55; P < .0001), 0.44 (95% CI, 0.41-0.48; P < .0001), and 0.17 (95% CI, 0.15-0.18; P < .0001), respectively. These data strongly support the clinical observation that patients infected with more recent variants are at a significantly lower risk of developing associated chemosensory loss.

COVID-19-Associated Chemosensory Loss Continues to Decline.

Chemosensory losses have long been considered a cardinal symptom of COVID-19 infection. Recent studies have shown changing symptom profiles with COVID-19, including decreasing incidence of olfactory losses. We accessed the National COVID Cohort Collaborative database to identify patients with and without smell and taste loss within 2 weeks of COVID-19 diagnosis. Peak prevalence time intervals for variants were determined from Covariants.org. Using rates of chemosensory loss during the peak time interval for "Untyped" variants as baseline (4/27/2020-6/18/2020), odds ratios for COVID-19-associated smell or taste disturbance fell for each of the Alpha (0.744), Delta (0.637), Omicron K (0.139), Omicron L (0.079), Omicron C (0.061), and Omicron B (0.070) peak intervals. These data suggest that during the recent Omicron waves and potentially moving forward, the presence or absence of smell and taste disturbances may no longer have predictive value in the diagnosis of COVID-19 infection.

Comparison of readmission and complication rates between traditional sleep surgery and hypoglossal nerve stimulation.

Objective: This study aims to compare readmission and complication rates between hypoglossal nerve stimulation (HNS) and traditional sleep surgery (TSS) in the 90-day postoperative period using a federated electronic health record (EHR) database. Methods: We queried TriNetX, a global federated health research network providing access to EHR data from approximately 70 million patients in 49 large health care organizations to identify individuals who underwent either HNS or TSS for obstructive sleep apnea (OSA) from April 2014 to March 2021. Propensity scores based on demographics and obesity were used to balance groups. We compared the frequency of readmission/representation and surgical-related complication rates between cohorts. Results: After propensity score matching of HNS versus palatal surgery (n = 1014 in each cohort) and HNS versus multilevel surgery (n = 374 in each cohort), we found palatal and multilevel surgery had a significantly higher risk of readmission versus HNS. (12% vs. 4%, p < .0001). Palatal surgery complication rate was also higher than HNS (21% vs. 2%, p < .0001). Multi-level surgery results were similarly higher (22% vs. 3%, p < .001). The most common diagnoses at ER readmission for TSS were procedural complications and pain, while common diagnoses for HNS readmission were general complaints such as malaise and headache. Conclusions: Hypoglossal nerve stimulation has lower risk of readmission and postoperative complications than traditional sleep surgery as demonstrated in a large research network database analysis. Level of Evidence: 3.

International consensus statement on allergy and rhinology: Olfaction.

BACKGROUND: The literature regarding clinical olfaction, olfactory loss, and olfactory dysfunction has expanded rapidly over the past two decades, with an exponential rise in the past year. There is substantial variability in the quality of this literature and a need to consolidate and critically review the evidence. It is with that aim that we have gathered experts from around the world to produce this International Consensus on Allergy and Rhinology: Olfaction (ICAR:O). METHODS: Using previously described methodology, specific topics were developed relating to olfaction. Each topic was assigned a literature review, evidence-based review, or evidence-based review with recommendations format as dictated by available evidence and scope within the ICAR:O document. Following iterative reviews of each topic, the ICAR:O document was integrated and reviewed by all authors for final consensus. RESULTS: The ICAR:O document reviews nearly 100 separate topics within the realm of olfaction, including diagnosis, epidemiology, disease burden, diagnosis, testing, etiology, treatment, and associated pathologies. CONCLUSION: This critical review of the existing clinical olfaction literature provides much needed insight and clarity into the evaluation, diagnosis, and treatment of patients with olfactory dysfunction, while also clearly delineating gaps in our knowledge and evidence base that we should investigate further.

Impact of Sinus Surgery on Hospital Utilization for Complications of Sinusitis.

BACKGROUND: Sinusitis complications are potentially lethal conditions that generally require extensive treatment and thus place a significant burden on the health-care system. The purpose of this study was to assess the impact of surgery on hospital utilization associated with treatment of sinusitis complications. METHODS: Retrospective cohort study using a national hospital database. The 2012 to 2013 National Inpatient Sample was queried for adult patients with sinusitis and complications. Patients were grouped based upon the presence or absence of sinus procedures. Patient demographics and health status, hospital characteristics, length of stay (LOS), and charges were determined. RESULTS: Of 1645 patients with sinusitis and associated complications, 232 (14%) underwent sinus procedures. These patients had higher LOS (8.0 ± 7.3 days vs 4.3 ± 5.2 days; P < .001) and charges (US$96 107 ± 108 089 vs US$30 661 ± 47 138; P < .001) than nonprocedure patients. Increased time to procedure in one operation patients (n = 209) of more than 2 days increased total LOS (11.4 ± 9.3 days vs 6.2 ± 5.5 days; P < .001) and charges (US$120 306 ± 112 748 vs US$76 923 ± 81 185; P = .005). Patients with multiple sinus procedures (n = 23) versus one had increased LOS and charges, despite no time difference from admission to first procedure (P = .35). On regression analysis, sinus procedure patients had excess LOS of 0.827 days and charges of US$36 949. CONCLUSION: Although often necessary, sinus procedures lead to increased LOS and charges. As prolonged time to sinus procedure and revision operations also increase charges, shorter trials of medical therapy and earlier surgical intervention may improve outcomes and reduce costs.

Epithelioid Sarcoma of the Tongue: An Unusual Tumor Mimic for Squamous Cell Carcinoma.

INTRODUCTION: Epithelioid sarcoma is a rare soft tissue malignancy that usually presents in the distal extremities along fascial planes, aponeuroses or tendon sheaths. Very rarely, it presents as a primary or metastatic lesion of the head neck. METHODS: Chart review and comprehensive literature review using PubMed and Google Scholar. RESULTS: A 17-year-old non-smoker was referred for evaluation of an ulcerative lesion of the right anterior-lateral tongue, progressing over several months. Incisional biopsy was concerning for squamous cell carcinoma. He underwent partial glossectomy and bilateral selective neck dissections, with reconstruction using a radial forearm free flap. Final pathology was consistent with epithelioid sarcoma, proximal type, demonstrating perineural invasion and close margins. Post-operative PET scan showed no persistent nor metastatic disease. He underwent post-operative radiation therapy to a total dose of 56 Gy to the primary site. CONCLUSION: Epithelioid sarcoma is a rare malignancy usually presenting in the extremities of young adults, which uncommonly presents in the head and neck as a primary or metastatic lesion. The infrequency of these lesions has prevented development of evidence-based treatment recommendations. As with most sarcomas, surgery is the mainstay of therapy for epithelioid sarcoma, while radiation has been used in an adjunctive role. Although a rare lesion, epithelioid sarcoma should be considered in the differential diagnosis for atypical epithelioid lesions of the tongue and oral cavity when patient demographics, gross lesion characteristics, or histopathology are not entirely consistent with more common lesions, such as squamous cell carcinoma.

Subjective Changes in Smell and Taste During the COVID-19 Pandemic: A National Survey-Preliminary Results.

Since the COVID-19 pandemic began, many individuals have noted acute loss of smell and/or taste, although not all patients with these symptoms are tested for COVID-19. To better characterize all patients with these rare symptoms, a national survey was created. Over 13 days in April 2020, a total of 220 people completed the survey in its entirety, representing a wide geographic distribution across the United States. Of the 220 respondents, 93 (42%) were diagnosed with COVID-19, and 127 (58%) were not. A total of 37.7% of respondents reported changes in smell/taste as the initial or sole presentation of their condition. Most but not all patients had other symptoms suggestive of COVID-19 at the time of chemosensory loss. Despite its inclusion as a major symptom of COVID-19 by the CDC (Centers for Disease Control and Prevention), respondents with additional CDC-defined symptoms associated with COVID-19 were statistically more likely to be tested/diagnosed than those without.

Prevalence of carotid stenosis following radiotherapy for head and neck cancer: A systematic review and meta-analysis.

BACKGROUND: Radiation to the head and neck is a well-established risk factor for the development of carotid artery stenosis. Our objective was to identify the prevalence, incidence, and degree of carotid stenosis in patients with a history of head and neck irradiation. METHODS: This study was performed according to the PRISMA guidelines. A random effects model meta-analysis was conducted. RESULTS: Nineteen studies comprising 1479 patients were included. The prevalence of carotid stenosis >50%, >70%, and carotid occlusion was 25% (95% CI: 19%-32%), 12% (95% CI: 7%-17%), and 4% (95% CI: 2%-8%), respectively. The cumulative 12-month incidence of carotid stenosis >50% was 4% (95% CI: 2%-5%), the 24-month was 12% (95% CI: 9%-15%), and the 36-month was 21% (95% CI: 9%-36%). CONCLUSIONS: The yearly incidence of carotid stenosis >50% increased every year during the first 3 years following radiotherapy. We propose routine yearly Doppler ultrasound screening beginning 1 year after head and neck radiotherapy.

Etiology of subjective taste loss.

BACKGROUND: Taste complaints are commonly encountered in clinical practice. Although changes in taste function may arise from varied etiologies, numerous other factors may impact patients' taste perceptions, the most common of which is olfactory dysfunction. Thus, patients with taste complaints may or may not have measurable deficits in taste function. This poses a challenge to providers faced with evaluation of patients with taste disorders, and may delay diagnosis and management. METHODS: We retrospectively examined records of 1108 patients evaluated at the Virginia Commonwealth University Health System Smell and Taste Clinic and compared patients' subjective taste complaints with results of objective testing of the senses of taste and smell. RESULTS: A total of 358 patients had a subjective taste complaint and results from both gustatory and olfactory function tests. Patients were grouped by subjective complaint as "taste only" (n = 63) or "taste and smell" (n = 295). Of patients reporting a "taste-only" complaint, 25.4% had abnormal gustatory function, whereas 44.4% had abnormal olfactory function. For those reporting taste-and-smell complaints, only 9.5% had abnormal gustatory function, whereas 86.8% had abnormal olfactory function. CONCLUSION: This study supports the hypothesis that patients who present with a taste complaint are more likely to have an underlying olfactory than gustatory impairment. However, those with a taste-only complaint are more likely to have objective gustatory deficits than those with a taste-and-smell complaint. These findings may prove useful to healthcare providers who evaluate patients presenting with complaints of taste loss.

The Burden of Sinusitis in Hematologic Transplant Patients: A National Perspective.

OBJECTIVES/HYPOTHESIS: To determine the impact of sinusitis on outcomes of hematologic transplant procedures. STUDY DESIGN: Retrospective analysis of a national hospital database. METHODS: The National Inpatient Sample database for 2012 to 2013 was queried using International Classification of Diseases, Ninth Revision, Clinical Modification codes to identify patients undergoing hematologic transplants. Patients were divided based upon the presence or absence of a concomitant diagnosis of acute or chronic sinusitis. Patient demographics, clinical characteristics, discharge results, lengths of stay (LOS), and costs were compared between groups. RESULTS: There were 7,069 hematologic transplant cases identified, 2.7% of which had a diagnosis of sinusitis. Sinusitis patients had a longer LOS after transplant (24.9 ± 15.9 days vs. 19.1 ± 17.4 days, P < .001) and higher total hospital charges ($487,941 ± $447,532 vs. $322,300 ± $369,596, P < .001) than nonsinusitis patients. There was no difference in mortality between the two groups (P = .75). The 23 (12%) sinusitis patients who underwent sinus procedures had a longer LOS after transplant (34.8 ± 25 days vs. 23.5 ± 13.7 days, P = .001) and higher total hospital charges ($857,891 ± $718,456 vs. $437,293 ± $372,075, P < .001) than sinusitis patients without sinus procedures. Linear regression showed that sinusitis patients had excess LOS after transplant of 2.442 days and cost of $82,000.098. CONCLUSIONS: This study demonstrates that presence of sinusitis in patients undergoing hematologic transplant is associated with increased LOS and higher total hospital charges. Increased focus on diagnosis and if possible treatment of sinusitis prior to admission for transplantation may help reduce the impact of sinusitis after hematologic transplant.

Head trauma and olfactory function.

Olfactory impairment is a well-established sequela of head injury. The presence and degree of olfactory dysfunction is dependent on severity of head trauma, duration of posttraumatic amnesia, injuries obtained, and as more recently established, age. Deficits in smell can be conductive or neurosensory, contingent on location of injury. The former may be amenable to medical or surgical treatment, whereas the majority of patients with neurosensory deficits will not recover. Many patients will not seek treatment for such deficits until days, weeks, or even months after the traumatic event due to focus on more pressing injuries. Evaluation should start with a comprehensive history and physical exam. Determination of the site of injury can be aided by CT and MRI scanning. Verification of the presence of olfactory deficit, and assessment of its severity requires objective olfactory testing, which can be accomplished with a number of methods. The prognosis of posttraumatic olfactory dysfunction is unfortunate, with approximately only one third improving. Emphasis must be placed on identification of reversible causes, such as nasal bone fractures, septal deviation, or mucosal edema/hematoma. Olfactory loss is often discounted as an annoyance, rather than a major health concern by both patients and many healthcare providers. Patients with olfactory impairment have diminished quality of life, decreased satisfaction with life, and increased risk for personal injury. Paramount to the management of these patients is counseling with regard to adoption of compensatory strategies to avoid safety risks and maximize quality of life. Practicing otolaryngologists should have a thorough understanding of the mechanisms of traumatic olfactory dysfunction in order to effectively diagnose, manage, and counsel affected patients.

Destructive lesion of the temporomandibular joint: A case of tophaceous pseudogout.

Tophaceous pseudogout of the temporomandibular joint is a rare entity that clinically and radiographically mimics neoplastic or infectious conditions. Diagnosis requires histopathologic examination. Given the rarity of this condition, there is a paucity of information pertaining to the surgical approach, reconstructive options, and postoperative outcomes.

A new clinical olfactory function test: cross-cultural influence.

OBJECTIVE: To investigate whether a new clinical olfactory test, the Odor Stick Identification Test for Japanese (OSIT-J), can be used to assess olfactory function cross-culturally in a US patient population. DESIGN: Cross-sectional prospective study. SETTING: A university medical center otolaryngology clinic. PATIENTS: Fifty US patients presenting with complaints of olfactory dysfunction from December 2004 to January 2006. INTERVENTIONS: Olfactory testing and patient interview. MAIN OUTCOME MEASURES: Comparison of test results obtained with the OSIT-J, the Connecticut Chemosensory Clinical Research Center (CCCRC) olfactory function test, and patients' self-reported level of olfactory function. Patients' opinions regarding the 2 test methods were also recorded. RESULTS: The mean +/- SD time required to administer the OSIT-J (8 +/- 1 minutes) was shorter than that required for the standard CCCRC test (21 +/- 6 minutes). Significant Spearman rank correlations were found between the OSIT-J and CCCRC test scores (r(s) = 0.80, P<.001, n = 50), and patients' self-reported level of olfactory function (r(s) = 0.73, P<.001, n = 50). Although 3 of the 13 odors used in the OSIT-J were not familiar to US subjects, patients reported that the OSIT-J was easier, more interesting, and the odors used more pleasant than the CCCRC test. CONCLUSIONS: Olfactory function tests developed in different countries should be evaluated to determine if a cross-cultural bias exists among test odorants. Although a cultural bias was detected for a few odorants, this study demonstrates that a modified version of the OSIT-J can be used to assess olfactory function in US patients.

Elimination of pain improves specificity of clinical diagnostic criteria for adult chronic rhinosinusitis.

OBJECTIVE: Determine whether the elimination of pain improves accuracy of clinical diagnostic criteria for adult chronic rhinosinusitis. STUDY DESIGN: Retrospective cohort study. METHODS: History, symptoms, nasal endoscopy, and computed tomography (CT) results were analyzed for 1,186 adults referred to an academic otolaryngology clinic with presumptive diagnosis of chronic rhinosinusitis. Clinical diagnosis was rendered using the 1997 Rhinosinusitis Taskforce (RSTF) Guidelines and a modified version eliminating facial pain, ear pain, dental pain, and headache. RESULTS: Four hundred seventy-nine subjects (40%) met inclusion criteria. Among subjects positive by RSTF guidelines, 45% lacked objective evidence of sinonasal inflammation by CT, 48% by endoscopy, and 34% by either modality. Applying modified RSTF diagnostic criteria, 39% lacked sinonasal inflammation by CT, 38% by endoscopy, and 24% by either modality. Using either abnormal CT or endoscopy as the reference standard, modified diagnostic criteria yielded a statistically significant increase in specificity from 37.1% to 65.1%, with a nonsignificant decrease in sensitivity from 79.2% to 70.3%. Analysis of comorbidities revealed temporomandibular joint disorder, chronic cervical pain, depression/anxiety, and psychiatric medication use to be negatively associated with objective inflammation on CT or endoscopy. CONCLUSION: Clinical diagnostic criteria overestimate the prevalence of chronic rhinosinusitis. Removing facial pain, ear pain, dental pain, and headache increased specificity without a concordant loss in sensitivity. Given the high prevalence of sinusitis, improved clinical diagnostic criteria may assist primary care providers in more accurately predicting the presence of inflammation, thereby reducing inappropriate antibiotic use or delayed referral for evaluation of primary headache syndromes.

Unusual paratracheal masses presenting with vocal fold paralysis.

Most paratracheal masses are of thyroid origin. We describe two cases of vocal fold paralysis that were caused by unusual paratracheal masses. In one case, a 35-year-old man was found to have a malignant lymphoma that originated in the mediastinum and extended above the clavicle. The other patient was a 53-year-old man with an enlarged left thyroid lobe, tumor invasion of the adjacent larynx and trachea, and multiple pulmonary nodules all due to adenoid cystic carcinoma. Unusual paratracheal masses presenting with vocal fold paralysis may mimic thyroid malignancies, thereby posing both diagnostic and therapeutic challenges. Fine-needle aspiration cytology is often helpful in making a definitive diagnosis, but incisional biopsy is necessary in some cases.
