Introduction: Esophageal safety following radiofrequency (RF) left atrial (LA) linear ablation has not been established. To determine the esophageal safety profile of LA linear RF lesions, we performed systematic esophagogastroduodenoscopy in all patients with intraesophageal temperature rise (ITR) ≥ 38.5°C., Methods and Results: Between December 2021 and July 2023, a total of 200 consecutive patients with atrial tachyarrhythmia (ATA) underwent linear ablation with posterior dome (roof or floor) or posterior mitral isthmus line transection. Patients with ITR ≥ 38.5°C were scheduled for esophageal endoscopy ~3 weeks after ablation. Patient and ATA characteristics, procedural parameters, endoscopy findings and ablation lesion data were collected and analyzed. One hundred thirty-three out of 200 (67%) patients showed ITR ≥ 38.5°C during LA linear ablation. ITR (with maximal temperature of 45.7°C) was more frequently observed during floor line ablation (82% of cases). ITR was less observed during roof line ablation (34%) and posterior mitral isthmus ablation (4%). Endoscopy, performed in 115 patients after 24 ± 10 days, showed esophageal ulceration in four patients (two patients Kansas City classification [KCC] 2a and two patients KCC 2b). No patient showed esophageal perforation or fistula., Conclusion: Temperature rise during LA linear ablation is frequent and ulceration risk exists, particularly when floor line is performed. Safety measures are needed to avoid potential severe complications like esophageal perforation and fistula., (© 2024 Wiley Periodicals LLC.)

Isolated esophageal ulcerations in Crohn's disease pose a great challenge in diagnosing and providing the correct treatment. We present the case of a 23-year-old woman with recurrent episodes of oral aphthosis, dysphagia, odynophagia and heartburn. Upper digestive endoscopy revealed an irregular mucosa with multiple ulcerations with irregular margins within the mid-esophagus. Immunoglobulin G (IgG) for cytomegalovirus and herpes virus were both positive. Four years after, she presented with the same symptoms and the involvement of ileo-colonic lesions, with pathological findings helped establish the Crohn's disease diagnosis. Crohn's disease represents an idiopathic chronic inflammatory gut disease, which can affect any part of the digestive tract. The onset by esophageal disease and no intestinal involvement is rare and challenging for a proper diagnosis.

Rationale: The deep-rooted pathogenesis of the human papilloma virus (HPV) infection is still uncertain and argumentative. As we know, a lot of cases of esophageal infections, such as esophageal squamous cell carcinoma (ESCC) and esophageal squamous papilloma (ESP), associated with HPV are reported. However, primary esophageal ulcer infection associated with HPV is unusual., Patient Concerns: This case is different from the other reports associated with HPV due to the patient's favorable prognosis., Diagnoses: We present a case of a man diagnosed in the Gastroenterology Department of Tianjin Hospital of Integrated Traditional Chinese and Western Medicine, which presented a deep and big esophageal ulcer with irregular borders caused by type 16 HPV infection., Interventions: The esophageal ulcer was treated with vidarabine monophosphate treatment., Outcome: The esophageal ulcer was cured., Lessons: We could put forward the diagnostic criteria available for diagnostic guidelines and 2 hypotheses that could possibly prevent esophageal carcinoma from happening.

Rationale: The fundamental pathogenesis of Behçet disease (BD) is still unclear and controversial. Many cases of oral aphthous ulcers and genital ulcers related to BD are reported; nevertheless, idiopathic giant esophageal ulcers related to BD are rare. A rare case for esophageal ulcers related to BD is presented., Patient Concerns: In China, BD is represented with esophageal involvement which is called esophageal BD (EBD)., Diagnoses: A 56-year-old man diagnosed to the Gastroenterology Department of Integrated Traditional Chinese and Western Medicine Hospital, for multiple discrete, elliptical esophageal ulcers related to BD., Interventions: The esophageal ulcers were treated with corticosteroid treatment for 12 weeks., Outcome: The esophageal ulcers were cured., Lessons: Our report might give further strength to avoiding the erroneous diagnosis or missed diagnosis for EBD, which is different from esophageal carcinoma, esophageal tuberculosis and esophageal Crohns disease.

The esophageal ulcer us a common complication in people affected by the acquired human immunodeficiency virus (HIV), especially in the final stages and in patients who develop an acute retroviral syndrome. Although, it can be caused by various infectious agents, such as species of candida, cytomegalovirus (CMV) and herpes simplex virus (HSV), no aetiological agent is successfully identified in a large proportion of patients and it is classified as idiopathic. We report the case of an idiopathic esophageal ulcer associated with the initial diagnosis of HIV-1.

Background: Recently, morbidities due to primary cytomegalovirus (CMV) infection have increased in young Japanese adults because of decreased anti-CMV antibodies in them. CMV infections are typically resolved naturally in immunocompetent individuals, and complications rarely occur. Here we present the case of an immunocompetent adult with CMV infection complicated by splenic infarctions and an esophageal ulcer., Case Report: A 37-year-old male complaining of a prolonged fever and liver injury was admitted to hospital for a closed examination. The patient had general malaise and mild appetite loss but no abdominal pain. Symptoms of infectious mononucleosis, including liver injury, appearance of atypical lymphocytes in the blood, and hepatosplenomegaly, were observed. A primary CMV infection was confirmed by CMV-IgM positive and CMV-IgG negative serological tests. Enhanced abdominal computed tomography confirmed hepatitis and splenic infarction, and an upper gastrointestinal endoscopy revealed an esophageal ulcer. The patient exhibited no predisposing risk factors for thrombosis, and he was diagnosed with splenic infarctions associated with CMV infection. Because the patient was immunocompetent, he underwent symptomatic therapy without antiviral or anticoagulant therapies. The treatment improved his overall condition. Including the present case, only 11 cases of CMV infections with splenic infarction in immunocompetent individuals have been reported. Contrary to what is observed in immunocompromised hosts, upper gastrointestinal lesions with CMV infection are rare in immunocompetent individuals. The esophageal lesion observed in our patient was a typical punched-out ulcer. The immunohistochemical staining of the tissue biopsies revealed that the ulcer was associated with CMV., Conclusion: Although splenic infarctions and esophageal ulcers are rare, they should be considered as potential complications accompanying CMV infection in immunocompetent individuals. The administration of symptomatic therapy should be considered even when the patient is immunocompetent.

Cameron lesions, as defined by erosions and ulcerations at the diaphragmatic hiatus, are found in the setting of gastrointestinal (GI) bleeding in patients with a hiatus hernia (HH). The study aim was to determine the epidemiology and clinical manifestations of Cameron lesions. We performed a retrospective cohort study evaluating consecutive patients undergoing upper endoscopy over a 2-year period. Endoscopy reports were systematically reviewed to determine the presence or absence of Cameron lesions and HH. Inpatient and outpatient records were reviewed to determine prevalence, risk factors, and outcome of medical treatment of Cameron lesions. Of 8260 upper endoscopic examinations, 1306 (20.2%) reported an HH. When categorized by size, 65.6% of HH were small (<3 cm), 23.0% moderate (3-4.9 cm), and 11.4% were large (≥5 cm). Of these, 43 patients (mean age 65.2 years, 49% female) had Cameron lesions, with a prevalence of 3.3% in the presence of HH. Prevalence was highest with large HH (12.8%). On univariate analysis, large HH, frequent non-steroidal anti-inflammatory drug (NSAID) use, GI bleeding (both occult and overt), and nadir hemoglobin level were significantly greater with Cameron lesions compared with HH without Cameron lesions (P ≤ 0.03). Large HH size and NSAID use were identified as independent risk factors for Cameron lesions on multivariate logistic regression analysis. Cameron lesions are more prevalent in the setting of large HH and NSAID use, can be associated with GI bleeding, and can respond to medical management., (© 2014 International Society for Diseases of the Esophagus.)

Button battery ingestion can lead to dangerous complications, including vasculoesophageal fistula formation. The presence of a vascular ring may complicate battery ingestion if the battery lodges at the level of the ring and its important vascular structures. We report a 4-year-old boy with trisomy 21 who was diagnosed with a vascular ring at the time of button battery ingestion and died 9 days after presentation due to massive upper gastrointestinal bleeding from esophageal erosion and vasculoesophageal fistula formation., (Copyright © 2015 Elsevier Inc.

Myxoma induces the onset of paraneoplastic syndromes by excreting various humoral mediators and is therefore known to present with diverse symptoms. A 40-year-old woman was admitted to our hospital for the treatment of an esophageal ulcer, the cause of which could not be identified on various examinations. Notably, a left atrial tumor was incidentally found on chest enhanced computed tomography. The esophageal ulcer, which was intractable to conventional therapy, improved with the administration of 5-aminosalicylate, a drug known to inhibit IL-1β. This inhibitory action effectively suppressed the development of myxoma-induced paraneoplastic syndrome.

We herein report the case of an HIV-positive man who was diagnosed with idiopathic esophageal and oropharyngeal ulceration. The esophageal and oropharyngeal ulcers were considered to be idiopathic and related to HIV infection after excluding the possibility of infection with known pathogens. Both the esophageal and oropharyngeal ulcers showed significant improvements following antiretroviral therapy alone. Idiopathic esophageal ulcers are a well-known complication of late-stage HIV infection. However, involvement of both the esophagus and pharynx is rare. Furthermore, antiretroviral therapy without concomitant steroids is effective against idiopathic esophageal and oropharyngeal ulcers related to HIV infection.

A 45-year-old male recipient of a renal allograft was admitted because of a giant oesophageal ulcer coinciding with leucopoenia. An extensive workup revealed no explanation for the ulcer and leucopoenia. Our final diagnosis by exclusion was an idiopathic giant oesophageal ulcer and late-onset neutropenia as consequences of rituximab induction therapy given during the transplant procedure. The patient fully recovered after treatment with prednisone. However, after four months, the ulcer and leucopoenia recurred and again successfully responded to treatment with prednisone.

Oesophageal ulcerations are generally rare occurrences that are most commonly associated with gastro-oesophageal reflux disorder. Other causes include medications and infections in immunocompromised patients. Among the medications used in daily practice, doxycycline is most commonly implicated. Multiple aetiologies are generally uncommon. We report a case of mid-oesophageal ulcerations secondary to doxycycline and herpes simplex virus infection in an immunocompetent patient.

We describe a case of an esophageal injury caused by insertion of a transesophageal cardiac echo probe in a 66-year-old man with an aberrant right subclavian artery, who was scheduled for Bentall surgery for aortic regurgitation and annuloaortic ectasia. Preoperative CT scan showed an aberrant right subclavian artery compressed from the back of the esophagus. General anesthesia was induced with midazolam and fentanyl, and maintained with midazolam, remifentanil and fentanyl. After induction of anesthesia, a transesophageal cardiac echo probe was inserted without abnormal resistance. The operation was performed uneventfully. On the second day after surgery, gastrointestinal bleeding was suspected and the upper gastrointestinal endoscopy (GIF) was performed. GIF revealed ulceration at the mid-esophagus and gastroesophageal junction, and a large amount of fresh blood in the stomach. The location of the ulcer at mid-esophagus was likely to be over the aberrant right subclavian artery. Ulcers were treated conservatively. GIF on the postoperative day 16 revealed that ulcers had healed. Transesophageal echo probe insertion is potentially hazardous in a patient with an aberrant right subclavian artery. Although aberrant right subclavian artery is rare, transesophageal echocardiography should be performed with extreme caution.

Background: Intralesional or systemic steroid administration is a promising strategy for the prevention of esophageal stricture after endoscopic therapy. The aim of this study was to evaluate the influence of steroid therapy on the process of healing of defects in the esophageal mucosa after endoscopic mucosal resection (EMR)., Methods: Nine beagle dogs were divided into three equal groups: group A, intralesional injection (n = 3), group B, peroral administration (n = 3), and group C, untreated control (n = 3). In group A, triamcinolone acetonide 1 ml (10 mg) was injected directly into the exposed submucosal layer immediately after EMR, and again on postoperative day (POD) 7. In group B, dogs were administered prednisolone 0.5 mg/kg/day orally for 14 days after EMR. In group C, 1 ml normal saline was injected by the same method as that used for group A. On POD 28, histological examination was performed to evaluate epithelialization, inflammation, angiogenesis, and atrophy of the muscularis propria., Results: In groups A, B, and C, the mean ulcer area was 50.1, 22.7, and 7.4 mm(2), respectively. The difference between groups A and C was significant (p < 0.01). Inflammatory cells were significantly more evident in the lesions of group A than in those of group C (p < 0.05). In all groups, atrophy of the muscularis propria was evident. However, transmural destruction and fibrosis were observed only in group A., Conclusion: It was speculated that the esophageal ulcer causes the fibrosis of the submucosa and atrophy of the muscularis propria during process of healing. Intralesional steroid injection deepened the esophageal ulcers and delayed epithelialization, whereas systemic administration did not clearly improve the lesion healing process.

Isolated adrenocorticotropic hormone (ACTH) deficiency (IAD) is a potentially fatal condition that is difficult to diagnose. The authors diagnosed IAD in a patient who presented with recurrent oesophageal ulceration resulting in oesophageal stenosis. The recurrent oesophageal ulcers were due to frequent nausea and vomiting that were the presenting digestive symptoms of adrenal insufficiency. Severe hypoglycaemia during this patient's course suggested the diagnosis of adrenal insufficiency. This case is educational because digestive symptoms are the most common symptoms in patients with adrenal insufficiency, but the diagnosis of adrenal insufficiency in such patients is not easy.

Background: Atrioesophageal fistula is an uncommon but life-threatening complication of atrial fibrillation (AF) ablation. Esophageal ulcerations (ESUL) have been proposed to be potential precursor lesions., Objective: The purpose of our study was to prospectively investigate the incidence of ESUL in a large patient population undergoing radiofrequency catheter ablation (RFA). Additionally, we aimed to link demographic data and lesion sets with anatomical information given by multislice computed tomography imaging and to correlate these data with the development of ESUL., Methods: This study included 267 patients and consecutively screened all individuals for evidence of ESUL 24 h after RFA of AF by endoscopy of the esophagus. A standardized ablation approach using a 25-W energy maximum at the posterior left atrial (LA) wall without esophagus visualization, temperature monitoring, or intracardiac ultrasound was performed., Results: In total, we found 2.2% of patients (6 of 267) presenting with ESUL. Parameters exposing a specific patient to risk of developing ESUL in univariate analysis were persistent AF (5 of 95, P = .023), additional lines performed (roofline: 6 of 114, P = .006; LA isthmus: 4 of 49, P = .011; coronary sinus: 5 of 66, P = .004), and LA enlargement (P = .001) leading to sandwiching of the esophagus between the LA and thoracic spine. Multivariate analysis revealed LA-to-esophagus distance as the only significant risk factor., Conclusion: This study is the first to link anatomical information and procedural considerations to the development of ESUL in radiofrequency ablation for AF. Furthermore, it reveals the correlation and individual impact of these factors. Not a single patient with pulmonary vein isolation alone developed ESUL., (Copyright 2010 Heart Rhythm Society.

Background: Cryoenergy is being increasingly used for atrial fibrillation (AF) ablation, but the thermal effect of cryoenergy on the esophagus remains undefined., Objective: This study examines the esophageal effects of cryoenergy used during AF ablation., Methods: Catheter ablation was performed using a cryoballoon catheter in 67 AF patients (Cryoballoon group), and a spot cryocatheter to complete irrigated radiofrequency lesion sets at segments in close proximity to the esophagus in 7 AF patients (Cryo-Focal group). A temperature probe monitored the luminal esophageal temperature (LET) in all patients; LET changes did not guide therapy. Post-procedural endoscopy was performed on 35 of 67 (52%) Cryoballoon and all Cryo-Focal patients., Results: Significant LET decreases (>1 degrees C) occurred in 62 of 67 (93%) Cryoballoon patients. LET continued to decrease after termination of cryoablation before recovering to normal. Temperature decreases were more pronounced during ablation at the inferior (3.1 degrees C) than superior pulmonary veins (1.5 degrees C); the lowest observed temperature was 0 degrees C. Post-procedural endoscopy showed esophageal ulcerations in 6 of 35 (17%) patients. There were no atrial-esophageal fistulas, and all ulcers had healed on follow-up endoscopy. Patients with and without ulceration differed with respect to mean LET nadir, cumulative LET decrease, and number of LETs <30 degrees C. In the Cryo-Focal group, 6 +/- 2 spot cryolesions per patient resulted in 1.3 +/- 1 LET decreases per patient, and an absolute nadir of 32.5 degrees C., Conclusion: Cryoballoon ablation can cause significant LET decreases, resulting in reversible esophageal ulcerations in 17% of patients. No ulcerations occurred with adjunctive spot cryoablation at regions near the esophagus during radiofrequency ablation procedures.

Introduction: Atrioesophageal fistula is an uncommon but often lethal complication of atrial fibrillation (AF) ablation. The purpose of our study was to prospectively investigate the incidence of esophageal ulcerations (ESUL) as well as the impact of energy settings, radiofrequency lesion sets, and direct visualization of the esophagus on esophageal wall injury., Methods and Results: One hundred seventy-five patients, 57.1% paroxysmal AF, 78.5% male, underwent AF ablation and esophagoscopy 24 hours thereafter. We performed a 2:1:1-randomization as follows:, Control Group: Ablation without visualization of the esophagus using 25 Watt (W) power limit on the posterior wall, n = 70. Visualization and 15 W maximum: Ablation guided by barium visualization of the esophageal course using a limit of 15 W, n = 35. Visualization and 25 W "short burns": Ablation guided by barium visualization using 25 W and "short burns" (max. 5 sec), n = 35. Patients performed under general anesthesia (n = 35) were separated as a nasogastric tube for visualization of the esophagus was used. In total, we found 2.9% of patients (5/175) presenting ESUL. Parameters discriminating the development of ESUL in a specific patient were type of AF, maximum energy delivered, usage of a nasogastric tube, and additional left atrial lines. Visualization of the esophageal course by barium contrast was not able to prevent ESUL., Conclusion: ESUL is a rare finding when using a reasonable energy maximum of 25 W with open-irrigated tip catheters at the posterior wall. Lower energy settings may increase safety without losing efficacy. Additional linear radiofrequency lesions increase the risk of ESUL development.

Primary human immunodeficiency virus (HIV) infection is a rarely diagnosed disease. The intestinal lymphocyte population represents a primary target of infection, virus replication, as well as cell infiltration and activation. The purpose of this study was to describe a patient suffering from esophageal giant ulcer as a clinical manifestation of primary HIV. In the present case of primary HIV infection a giant ulcer of the esophagus was diagnosed as the clinical manifestation. An upper endoscopy was performed and the biopsy specimens were further processed for immunohistochemical stainings characterizing the cellular infiltrate as well as cytokine production. In addition, seroconversion was documented and total viral load was determined. The esophageal ulceration presented the clinical manifestation of primary HIV infection since other causes of esophageal ulcerations could be excluded. The ulceration revealed an inflammatory infiltrate consisting of both CD4(+) and CD8(+) T cells. The vast majority of these cells expressed the activation marker CD38 and several cells showed interferon-gamma and interleukin-2 production. Furthermore, a substantial number of tissue infiltrating CD8(+) T cells expressed the cytotoxic molecule perforin. In addition, the HIV antigen p24 could be detected in the inflammatory infiltrate. Subsequent steroid treatment resulted in a relief of symptoms and healing of the ulcerations. These observations strongly suggest that infiltration of activated T cells plays a crucial role in the pathogenesis of giant ulcers during primary HIV infection.

Oesophageal ulcers occur mainly as a result of gastro-oesophageal reflux disease (GERD). However, pill-induced oesophageal ulcers are a fairly common event. The lesion is mainly due to entrapment of the pill and/or its chemical composition thereof. This case report describes an oesophageal mucosa ulcer occurred in a healthy 35-year old woman who had no previous history of oesophageal disorders and received homeopathic medication. The present case reveals that pill entrapment can occur even in the oesophagus of healthy young individuals and that oesophageal mucosal ulcer can be triggered by substances generally thought devoid of any potentially mucosal aggressive effect.

The involvement of the esophagus in tuberculosis (TB) is extremely rare. This is a case report of an immunocompetent male patient, who presented ganglionary TB reactivation, with the development of extensive esophageal ulcers. The endoscopic approach made the diagnosis possible and there was a total resolution of the symptoms after the treatment.

Purpose: To ascertain factors that could influence the development of ulcers and strictures in the definitive management of squamous cell carcinoma (SCC) of esophagus treated with external beam radiotherapy (EBRT), high-dose-rate (HDR) intralumenal radiotherapy (ILRT) with or without concurrent weekly cisplatin (CDDP @ 35 mg/m2) chemotherapy (CT)., Materials and Methods: Between 1990-2005, 244 patients with inoperable SCC of esophagus were identified from our database and grouped into one of the following: those receiving at least 60 Gy EBRT (Gp E, n=44); EBRT followed by HDR-ILRT (Gp E+I, n=98); at least 50 Gy EBRT with CT (Gp E+C, n=68); EBRT+HDR-ILRT + CT (Gp E+I+C, n=34). Ulcers (discovered on endoscopy) and strictures evident on a barium swallow (which needed dilatations) were scored as treatment induced, if the biopsy was negative. Factors likely to influence their outcome were analyzed., Results: The groups were matched for all patient and disease characteristics except pretreatment hemoglobin and Karnofsky performance score (KPS), which were lower in Gp E. The incidence of ulcers was 7%, 8%, 6% and 21% (P=0.08) while that of strictures was 14%, 9%, 21% and 41% (P=0.00) for the groups E, E+I, E+C and E+I+C respectively. On univariate analysis, patients with better KPS (P=0.03), treated with narrow applicators (6 mm vs. 10 mm, P=0.00), received CT (P=0.00) or assigned to Gp E+I+C (P =0.00) were more likely to develop strictures, with a trend for development of ulcers in Gp. E+I+C (P=0.08). Logistic regression retained only Gp E+I+C for development of ulcers (OR 10.36, 95% CI 1.2-89.1, P=0.03) and strictures (OR 4.2, 95% CI 1.4-12.6, P=0.00)., Conclusion: Treatment intensification as in Gp E+I+C results in about a three-fold increase in treatment induced late morbidity which can adversely impact on swallowing function and therefore emphasizes the need for optimisation of HDR-ILRT when used in a CT+RT protocol.

Hypothesis: Positron emission tomography can be useful in predicting response of esophageal cancer after preoperative chemo-radiation therapy (CRT). We evaluated the use of integrated computed tomography (CT)-PET among patients with esophageal cancer being considered for resection after CRT., Methods: Three reviewers blinded to clinical and pathologic staging retrospectively reviewed the CT-PET scans of patients with esophageal cancer after preoperative CRT who underwent esophagectomy. [F]-fluoro-2-deoxy-D-glucose uptake for residual malignancy was determined by visual analysis and semi-quantitatively when standardized uptake value (SUV) was > or =4., Results: Forty-two patients underwent esophageal resection. Using visual analysis, CT-PET had a sensitivity of 47% and specificity of 58% in detecting residual malignancy. Using semi-quantitative analysis, 19 patients had a SUV > or =4 in the region of the primary esophageal tumor and were interpreted as having residual malignancy (sensitivity 43%, specificity 50%). Of these 19, six had complete pathologic response to CRT. These false-positive results, due to therapy-induced ulceration detected at endoscopy, limit the use of CT-PET alone in detecting residual malignancy. Similarly, sensitivity (25%) and specificity (73%) of endoscopy/biopsy in detecting residual malignancy were poor. However, the accuracy of CT-PET in detecting residual malignancy was improved when combined with endoscopic findings. In the absence of ulceration at endoscopy, 8 of 8 patients with SUV > or =4 after chemo-radiation had residual malignancy at surgery., Conclusions: CRT-induced ulceration results in false-positive results on CT-PET and precludes accurate detection of residual esophageal tumor. However, CT-PET in combination with endoscopy is useful in identifying patients with a high risk of residual tumor post-CRT.

Intestinal Behcet's disease in a 38-year-old woman was diagnosed because of the history of recurrent oral aphthous ulcers, erythema nodosum-like eruptions, genital ulcer, and endoscopic findings of esophageal and ileocolonic punched-out ulcers with colonic longitudinal ulcers. Esophageal lesions and colonic longitudinal ulcers are rarely seen in intestinal Behcet's disease. The ulcers of esophagus and ileocolon healed with 3 wk of treatment with prednisolone and mesalazine without any adverse effect. Mesalazine may decrease the total dose of prednisolone required to treat the disease.

Multiple myeloma is a neoplasm of mature and immature plasma cells. A 50-year-old woman with lumbago, dysphagia, and left arm pain was presented. Upper endoscopical examination was performed. There was an exudate-covered ulcer in the distal esophagus, located at 30-32 cm from the incisors, covering the whole mucosa. Histopathological examination of the specimens obtained from the lesion showed the involvement of plasma cells consistent with multiple myeloma of IgG kappa subtype. Esophageal involvement of multiple myeloma should be kept in mind in patients presenting with dysphagia.
