Necrotizing sialometaplasia in two patients with bulimia and chronic vomiting

The Clinical and Psychopathological Profile of Inpatients with Eating Disorders: Comparing Vomiting, Laxative Abuse, and Combined Purging Behaviors

BACKGROUND/OBJECTIVES

The previous literature on purging behavior in eating disorders (EDs) suggests an overall more complicated clinical picture for individuals with this symptomatology. So far, no studies have analyzed the possible differences between the specific types of purging among ED inpatients.

METHODS

A clinical sample of 302 inpatients with EDs was classified according to no purging behaviors, vomiting, the abuse of laxatives, and both vomiting and the abuse of laxatives. Participants completed the following questionnaires: the Eating Disorder Examination Questionnaire (EDE-Q), Frost Multidimensional Perfectionism Scale (F-MPS), State-Trait Anxiety Inventory (STAI), and Beck Depression Inventory (BDI). Clinical information was collected for each individual.

RESULTS

Significant differences in the four groups were evidenced in age (p < 0.001), years of illness (p < 0.001), BMI at discharge (p < 0.001), STAI state anxiety (p < 0.001), STAI trait anxiety (p < 0.001), BDI (p < 0.001), EDE-Q eating concerns (p < 0.001), EDE-Q shape concerns (p < 0.001), EDE-Q weight concerns (p < 0.001), EDE-Q global score (p < 0.001), and F-MPS parental criticism (p < 0.001). ED inpatients with purging behaviors were older, had a longer duration of illness, higher parental criticism, and worse general and eating psychopathology. No differences emerged between the specific types of purging behavior.

CONCLUSIONS

Purging behavior is a marker of severity in EDs independently of the specific type of purging. The appearance of any purging behavior must be regarded as a considerable red flag and be followed by an intensification of the cure.

Atypical Presentation of Necrotizing Sialometaplasia of the Hard Palate: A Diagnostic Dilemma

Necrotizing sialometaplasia refers to a benign, uncommon, and self-limiting inflammatory reaction concerning the salivary gland tissue, which both clinically and histologically may be easily mistaken for mucoepidermoid carcinoma or squamous cell carcinoma. This may cause irrelevant surgical intervention. Minor salivary glands are the most commonly affected salivary gland, with the hard palate being the most usual site. However, it can involve the other areas in which salivary gland tissue is present in the other oral subsites and pharyngeal areas. Due to the lack of knowledge about this entity and its histological similarities with carcinomas, particularly mucoepidermoid carcinoma, the differential diagnosis of this lesion is difficult. Local ischemia is thought to be the primary cause, leading to the pathogenesis of necrotizing sialometaplasia, and the infiltration of local anesthesia following dental procedures at the palatal region is the leading cause.

Oral cavity and eating disorders: An insight to holistic health

Oral health is vital to the general well being and is a time-tested indicator of the systemic health of an individual. Oral cavity may be the primary site affected in endocrine disorders, renal disorders, gastrointestinal, cardiovascular, hematological, autoimmune cutaneous disorders, and psychosomatic disorders. Eating disorders (primarily Anorexia nervosa and bulimia) are psychosomatic disorders having multifaceted etiology, and characterized by abnormal eating patterns. In many cases, the oral cavity may be the only site of the manifestations of eating disorders. An oral physician may often unveil the mystery of this underlying systemic pathology by a vigilant and meticulous examination of the oral cavity. This not only helps in nabbing the disease in its early course but also prevents the patients from the appalling consequences due to the disease. This article aims to highlight the etiopathogenesis and various oral features in eating disorders. The oral physician should be familiar with the bizarre oral features of eating disorders and should work in close connection with other healthcare physicians to prevent the psychosomatic and systemic consequences.

Necrotizing sialometaplasia: a malignant masquerade but questionable precancerous lesion, report of four cases

BACKGROUND

Necrotizing sialometaplasia (NSM) is an extremely rare benign lesion with an uncertain pathogenesis. The differential diagnosis of this lesion is challenging due to little familiarity with this entity and histologic similarity with carcinomas, especially mucoepidermoid carcinoma (MEC). The purpose of this study is to raise awareness about NSM, which is often overlooked or misdiagnosed as malignancy in a small biopsy.

METHODS

We reviewed all biopsy materials taken from the oral cavity in a single institution in Korea from 2012 to 2018 and found 4 cases of NSM out of 726. Clinicopathologic characteristics and comparison with other lesions were discussed.

RESULTS

Unlike previous reports, patients in our series were relatively young, and NSM was not related to smoking and not associated with malignancies, although one patient was misdiagnosed with MEC on the basis of the initial biopsy. High-grade squamous dysplasia was observed in one patient; however, all four patients showed excellent prognoses without further management.

CONCLUSIONS

A conservative approach is recommendable for necrotizing lesions of the palate in young adults to avoid unnecessary treatment. However, careful monitoring is also required due to uncertainty of premalignant potential.

Which Symptoms, Complaints and Complications of the Gastrointestinal Tract Occur in Patients With Eating Disorders? A Systematic Review and Quantitative Analysis

BACKGROUND

Eating disorders (ED) such as anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED) are often accompanied by a variety of psychological and physical comorbidities. Gastrointestinal (GI) symptoms are a classical feature in most patients with ED. The heterogeneity of studies on this topic is high, making it difficult to have a clear overview. The aim of this systematic review is therefore to provide an overview of subjectively and objectively measured differences and changes in the GI tract in patients with EDs, along with the occurrence of GI complications.

METHODS

A systematic literature search was conducted in PubMed, Web of Science, and Google Scholar to find all relevant studies examining GI problems in AN, BN, and BED. Quantitative analyses were performed for objective GI physiology measures where applicable.

RESULTS

The review differentiated between ED types and also between studies that report GI outcomes of ED in (i) human studies with an ED diagnosis excluding case reports that provide an overview of GI problems in ED and (ii) case reports with an ED diagnosis describing rare GI complications in ED. GI symptoms and impaired gastric transit times were frequent features of EDs with specific differences found for the ED types. During the time course of treatment, GI symptoms changed and/or improved but not completely. GI complications extended the range of GI problems observed, including a variety of serious complications such as gastric dilatation.

CONCLUSIONS

Problems of the GI tract are frequent in patients with ED and it is likely that they complicate therapy, especially in patients with AN.

Necrotizing Sialometaplasia of the Hard Palate in a Patient Treated with Topical Nonsteroidal Anti-Inflammatory Drug

Necrotizing sialometaplasia is a rare, benign, self-limiting, necrotizing process involving the minor salivary glands, mainly the mucoserous glands of the hard palate. It is thought to be the result of an ischemic event of the vasculature supplying the salivary gland lobules. Some predisposing factors such as smoking, use of alcohol, denture wearing, recent surgery, traumatic injuries, respiratory infections, systemic diseases bulimia, and anorexia have been described. Herein we present a case of necrotizing sialometaplasia of the hard palate in a patient without known predisposing factors, in our opinion, resulting from the use of topical anti-inflammatory drug. After diagnosis, the patient underwent treatment with chlorhexidine gluconate and a full palatal acrylic guard to protect the exposed bone from food residues during meals. After the sixth week the lesion regressed.

The medical complications associated with purging

OBJECTIVE

Purging behaviors, including self-induced vomiting, laxative abuse, and diuretic abuse, are present across many of the eating disorders. Here we review the major medical complications of these behaviors.

METHOD

Although we identified over 100 scholarly articles describing medical complications associated with purging, most papers involved case studies or small, uncontrolled samples. Given the limited evidence base, we conducted a qualitative (rather than systematic) review to identify medical complications that have been attributed to purging behaviors.

RESULTS

Medical conditions affecting the teeth, esophagus, gastrointestinal system, kidneys, skin, cardiovascular system, and musculoskeletal system were identified, with self-induced vomiting causing the most medical complications.

DISCUSSION

Purging behavior can be associated with severe medical complications across all body systems. Mental health professionals should refer patients with purging behaviors to medical providers for screening and treatment as needed. The medical work-up for individuals with eating disorders should include a comprehensive metabolic panel, complete blood count, and a full body exam including the teeth to prevent severe complications. Medical providers should screen patients for purging behaviors and associated medical complications, even in the absence of an eating disorder diagnosis, to increase the detection of eating disorders. Recognizing the link between purging and medical complications can aid in identifying potential eating disorders, particularly those that often elude detection such as purging disorder.

Necrotizing sialometaplasia-like change of the esophageal submucosal glands is associated with Barrett's esophagus

The esophageal submucosal glands (SMG) protect the squamous epithelium from insults such as gastroesophageal reflux disease by secreting mucins and bicarbonate. We have observed metaplastic changes within the SMG acini that we have termed oncocytic glandular metaplasia (OGM), and necrotizing sialometaplasia-like change (NSMLC). The aim of this study is to evaluate the associated clinicopathological parameters of, and to phenotypically characterize the SMG metaplasias. Esophagectomy specimens were retrospectively assessed on hematoxylin and eosin sections and assigned to either a Barrett's esophagus (BE) or non-BE control group. Clinicopathologic data was collected, and univariate analysis and multivariate logistic regression models were performed to assess the adjusted associations with NSMLC and OGM. Selected cases of SMG metaplasia were characterized. SMG were present in 82 esophagi that met inclusion criteria. On univariate analysis, NSMLC was associated with BE (p = 0.002). There was no relationship between NSMLC and patient age, sex, tumor size, or treatment history. OGM was associated with BE (p = 0.031). No relationship was found between OGM and patient age, sex, or tumor size. On multivariate analysis, BE was independently associated with NSMLC (odds ratio [OR] 4.95, p = 0.003). Treatment history was also independently associated with OGM (p = 0.029), but not NSMLC. Both NSMLC and OGM were non-mucinous ductal type epithelia retaining a p63-smooth muscle actin co-positive myoepithelial cell layer. NSMLC and OGM were present in endoscopic mucosal resection specimens. Our study suggests that SMG metaplasia is primarily a reflux-induced pathology. NSMLC may pose diagnostic dilemmas in resection specimens or when only partially represented in mucosal biopsies or endoscopic resection specimens.

Necrotizing sialometaplasia of the palatal mucosa in patient with history of anorexia: review and case report

Necrotizing sialometaplasia is a self-limiting disorder affecting minor salivary glands resembling a malignant process both clinically and histopathologically. The etiology of this rare inflammatory` disorder is related to an ischemic event. Identified risk factors include alcohol abuse, smoking, drugs, denture wearing, injury and systemic diseases. Also reported are cases of necrotizing sialometaplasia associated with bulimia. This paper identifies the whole body incitement among additional risk factors by presenting a case of necrotizing sialometaplasia in an 18 year old patient with the history of anorexia nervosa. Furthermore it describes the effects of extreme cooling of palatal mucosa with ice chips resulting in constriction of blood vessels as the direct cause, reinforcing ischemic etiology of necrotizing sialometaplasia.

Necrotizing sialometaplasia of tongue

Necrotizing sialometaplasia, is a benign inflammatory lesion primarily involving the minor salivary glands of the hard palate. The lesion often presents itself as a deep-seated palatal ulcer with clinical and histological features similar to those of a malignant neoplasm. Here we report a case of necrotizing sialometaplasia in a 40-year-old female, present on the lateral border of the tongue, mimicking squamous cell carcinoma, clinically. A correct diagnosis to avoid mutilant surgical treatments is essential, considering that it is a self-limiting disease.

Necrotizing sialometaplasia in a patient with an eating disorder: palatal ulcer accompanied by dental erosion due to binge-purging

This report describes a case of necrotizing sialometaplasia (NS) accompanied by significant dental erosion of the maxillary teeth of the palatal surfaces owing to chronic self-induced vomiting. This observation contributed to the determination of an immediate and appropriate provisional diagnosis of NS in a patient with an eating disorder, which subsequently was confirmed histopathologically as NS. The diagnostic challenges presented by NS associated with eating disorders and its management are discussed.

The clinical, histologic, and treatment spectrum in necrotizing sialometaplasia

OBJECTIVES

The aim of this report was the clinical and histologic characterization of necrotizing sialometaplasia.

STUDY DESIGN

We performed a retrospective case series analysis.

RESULTS

The study included 4 women 29-71 years old. Possible contributing factors (drugs, alcohol abuse, bulimia, smoking, and pancreatic cancer) were identified. Patients presented with unilateral or bilateral rapidly progressing painful palatal ulcers. Necrotic salivary glands and inflammation were universal microscopic features; ductal metaplasia was present in only 1 case. Thrombosis and heavy fungal and bacterial overgrowth were observed in 1 case. In 3 of the cases the lesions healed within 4-6 weeks under conservative supportive care, whereas in 1 case persistent enlargement up to 25 mm diameter was observed. Surgical debridement combined with a palatal guard resulted in complete healing within 12 weeks.

CONCLUSIONS

Significant variations may be observed in both clinical and microscopic manifestations of necrotizing sialometaplasia. Although this disease is considered to be self-limiting in the majority of cases, surgical intervention can be considered in unusually large cases.

Significance of Ki-67 and p53 immunoexpression in the differential diagnosis of oral necrotizing sialometaplasia and squamous cell carcinoma

Necrotizing sialometaplasia (NS) is a benign condition that usually involves the hard palate and can be mistaken for invasive squamous cell carcinoma (SCC). In this study, we have demonstrated that p53 and Ki-67 staining may assist in the differential diagnosis of NS from SCC. Thirteen cases of NS and 20 cases of oral cavity SCC were randomly selected from our surgical pathology archive from 1992 to 2009. Each case was additionally stained with Ki-67, p53, BCL-2, p16, and epidermal growth factor receptor (EGFR) antibodies. All 13 cases of NS were negatively stained for BCL-2, EGFR, and Ki-67. Three cases (23%) showed weak and focal positive nuclear staining for p53. Two cases (15%) showed positive staining for p16. In 16 well-differentiated SCC cases, p53 was positive in 12 cases (75%); BCL-2, p16, EGFR were positive in 3 cases (18%); and Ki-67 was positive in all cases (100%). In 4 moderately differentiated SCC cases, p53 expression was positive in all cases. Two tumors (50%) had a positive expression of BCL-2. Three cases (75%) had a positive p16 staining, and 1 (25%) had a positive EGFR staining. All cases were positive with high nuclear staining greater than 35% of cells for Ki-67. Ki-67 and p53 showed more intense staining and increased in moderately differentiated SCC comparing with well-differentiated SCC and NS. BCL-2, EGFR, and p16 had the same pattern of staining with the same extent in NS and SCCs. The diagnosis of NS may be difficult and may be supplemented via immunohistochemistry by demonstrating focal or absent p53, low to absent Ki-67 (<10% of cells). Although Ki-67 and p53 staining are generally more intense and are increased in malignancy, these findings may be helpful adjuncts in the differential diagnosis of NS from SCC in appropriate clinical setting.

Necrotizing sialometaplasia of palate: a case report

Necrotizing sialometaplasia (NS) which mimics malignancy both clinically and histopathologically is an uncommon benign, self-limiting inflammatory disease of the mucus-secreting minor salivary glands. The lesion is believed to be the result of vascular ischemia that may be initiated by trauma. Till date, the diagnosis of NS remains a challenge. This report demonstrates a case of NS in a 73-year-old male patient who presented with an ulcerative lesion in his palate. He had a history of local trauma and was long-term user of salbutamol inhaler. An incisional biopsy was carried out and the diagnosis was established through history, clinical examination, histopathology using Hematoxylin and Eosin stain. The patient was given symptomatic treatment and the lesion healed in about 7 weeks.

Necrotizing sialometaplasia: a practical approach to the diagnosis

CONTEXT

Necrotizing sialometaplasia is a benign, self-limited lesion of both major and minor salivary glands, although more commonly the latter. It can represent a diagnostic dilemma and may be mistaken for a malignant neoplasm, such as mucoepidermoid carcinoma, as well as invasive squamous cell carcinoma. A major causal relationship has been ascribed to ischemia. Bulimia, an eating disorder with increasing prevalence in our society, may also be an underlying underreported cause.

OBJECTIVE

To discuss the potential pathogenesis, diagnostic pitfalls, and the application of immunohistochemistry as an aid in the diagnosis of necrotizing sialometaplasia.

DATA SOURCES

This report uses a previously published case history for illustrative purposes and a review of the current literature.

CONCLUSIONS

The diagnosis of necrotizing sialometaplasia may be difficult and is reliant upon a well-oriented biopsy section and a complete clinical history. Diagnosis may be further supplemented via immunohistochemistry, demonstrating focal to absent immunoreactivity for p53, low immunoreactivity for MIB1 (Ki-67), and the presence of 4A4/p63- and calponin-positive myoepithelial cells. Interpreted in context collectively, these findings may be helpful adjuncts in the diagnosis of necrotizing sialometaplasia; nonetheless, to date, hematoxylin-eosin staining remains the gold standard.

Case report. MRI findings of necrotizing sialometaplasia

Necrotizing sialometaplasia (NS) is a benign self-limiting inflammatory disease of mucus-secreting glands, mainly involving the minor salivary glands. This lesion can mimic a malignant neoplasm, as more frequently it manifests as a submucosal swelling or as an ulcer of the palate. Awareness of the disease is crucial to avoid undue surgical treatment. We herewith report MR findings in a histologically proven case of NS.

Palatal Ulcers due to Vomiting after Gastric Band Tightening

Adjustable gastric banding is a widely used modality in some countries for the treatment of morbid obesity, and several complications have been reported. We report the unusual case of a patient who developed bilateral ulcers of the palate after intense vomiting caused by tightening of her gastric band.

Necrotizing sialometaplasia associated with bulimia: case report and literature review

Necrotizing sialometaplasia (NSM) is a self-limiting disorder affecting mainly the minor salivary glands. The significance of NSM resides in its clinical and histopathological resemblance to carcinoma. Few cases of NSM associated with eating disorders have been reported to date. We present here the clinical features and histomorphology of an additional case of bulimia-associated NSM closely mimicking an invasive carcinoma. A high index of suspicion and good communication between clinician and pathologist are essential in recognizing this entity and preventing unnecessary surgical therapy.

Eating disorders and oral health: A review of the literature

This article is a review of the recent literature pertaining to the oral sequelae of eating disorders (EDs). Dentists are recognized as being some of the first health care professionals to whom a previously undiagnosed eating disorder patient (EDP) may present. However, despite the prevalence (up to 4 per cent) of such conditions in teenage girls and young adult females, there is relatively little published in the recent literature regarding the oral sequelae of EDs. This compares unfavourably with the attention given recently in the dental literature to conditions such as diabetes mellitus, which have a similar prevalence in the adult population. The incidence of EDs is increasing and it would be expected that dentists who treat patients in the affected age groups would encounter more individuals exhibiting EDs. Most of the reports in the literature concentrate on the obvious clinical features of dental destruction (perimolysis), parotid swelling and biochemical abnormalities particularly related to salivary and pancreatic amylase. However, there is no consistency in explanation of the oral phenomena and epiphenomena seen in EDs. Many EDPs are nutritionally challenged; there is a relative lack of information pertaining to non-dental, oral lesions associated with nutritional deficiencies.

Review article: oral ulcers and its relevance to systemic disorders

Oral ulceration is a common problem, and is sometimes a marker of gastroenterological disease. Patients with signs or symptoms of oral ulcers are sometimes referred to gastroenterology clinics, however, in most instances the ulcers does not reflect gastrointestinal disease. Indeed, a spectrum of disorders other than those of the gut can give rise to oral mucosal ulcers ranging from minor local trauma to significant local disease such as malignancy or systemic illness. This present article reviews aspects of the aetiology, diagnosis and management of common ulcerative disorders of the oral mucosa.

Sialosis and necrotising sialometaplasia in bulimia; a case report

Salivary gland involvement, particularly salivary gland enlargement (sialosis), is a recognised complication in bulimia. We report the rare association of sialosis and necrotising sialometaplasia with bulimia in the same patient. The association of sialosis and necrotising sialometaplasia in the same patient with bulimia has been reported previously in two patients and may be coincidental, but the appearance in this additional patient suggests it may be prudent to explore this further.

Necrotizing sialometaplasia: An unusual bilateral presentation associated with antecedent anaesthesia and lack of response to intralesional steroids. Case report and review of the literature

Necrotizing sialometaplasia is a self-limiting, variably ulcerated benign process affecting minor salivary glands. Accurate histological diagnosis is paramount, as it has been mistaken for malignancy, which has resulted in excessively aggressive and unnecessary radical surgery. A unique case of bilateral necrotizing sialometaplasia, presenting with anaesthesia of the greater palatine nerves, is described. An attempt at active therapy with intralesional steroids had no effect on the course of the condition.
