Eosinophilic ulcer of the oral mucosa: a distinct entity or a non-specific reactive pattern?

Traumatic ulcerative granuloma with stromal eosinophilia (TUGSE): Case report of a 63-year-old male patient with a rare self-healing oral mucosal lesion

Traumatic Ulcerative Granuloma with Stromal Eosinophilia (TUGSE)/Riga Fede disease is a rare mucosal and submucosal benign reactive inflammatory process, usually involving the tongue. Trauma is believed to be a major factor amongst the multiple pathogenic mechanisms that have been hypothesized in TUGSE. The lesion presents as an isolated indurated or even ulcerated mass, which may mimic, clinically a squamous cell carcinoma (SCC). We herein report a case of TUGSE in a 63-year-old male referred by his treating physician for high suspicion of tongue malignancy. Histopathological examination confirmed the diagnosis of TUGSE, without any evidence of a neoplasic, infectious or hematologic process. TUGSE occurs in patients with an age range of 41-60 years. Sufficiently deep biopsies with comprehensive immunohistochemical and molecular analyses are mandatory to confirm the benign nature of the lesion and to, definitely, rule out malignancy. This report highlights the need for adequate histological differential diagnosis to avoid inappropriate heavy treatments in a benign condition.

Eosinophils in Oral Disease: A Narrative Review

The prevalence of diseases characterised by eosinophilia is on the rise, emphasising the importance of understanding the role of eosinophils in these conditions. Eosinophils are a subset of granulocytes that contribute to the body's defence against bacterial, viral, and parasitic infections, but they are also implicated in haemostatic processes, including immunoregulation and allergic reactions. They contain cytoplasmic granules which can be selectively mobilised and secrete specific proteins, including chemokines, cytokines, enzymes, extracellular matrix, and growth factors. There are multiple biological and emerging functions of these specialised immune cells, including cancer surveillance, tissue remodelling and development. Several oral diseases, including oral cancer, are associated with either tissue or blood eosinophilia; however, their exact mechanism of action in the pathogenesis of these diseases remains unclear. This review presents a comprehensive synopsis of the most recent literature for both clinicians and scientists in relation to eosinophils and oral diseases and reveals a significant knowledge gap in this area of research.

Traumatic Ulcerative Granuloma with Stromal Eosinophilia on the Tongue

BACKGROUND

Traumatic Ulcerative Granuloma with Stromal Eosinophilia, commonly known as Eosinophilic Ulcer, is a reactive solitary and self-limiting benign lesion. It manifests as a punched-out ulcer with a distinct surrounding indurated border, often raising concerns about malignancy.

METHODS

A 44-year-old male presented with a painless, indurated tongue ulcer evolving over three months. Despite being asymptomatic, the patient underwent an incisional biopsy due to suspicions of oral squamous cell carcinoma.

RESULTS

Histological analysis revealed a disrupted epithelial lining, dense necrotic connective tissue, and a fibrino-purulent pseudomembrane. Proximal to the ulcer, a collar-like projection of reactive epithelial tissue hyperplasia was noted, accompanied by mononuclear cells and a predominantly histiocytic infiltrate in the submucosal layer surrounding skeletal muscle fibers. The final diagnosis was Traumatic Ulcerative Granuloma with Stromal Eosinophilia. Remarkably, the lesion spontaneously healed within 2 weeks post-biopsy, with no recurrence over 6 months.

CONCLUSION

This case emphasizes considering this benign condition in the differential diagnosis of oral ulcers, highlighting the importance of accurate histopathological evaluation to rule out cancer.

Epithelioid hemangioma (ALHE) on the tongue of an infant treated with oral corticosteroids: A case report and review of the literature

Epithelioid hemangioma or angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare benign vascular lesion presenting as multiple nodules on the head and neck. Surgery had been considered to be the best treatment modality for ALHE. We report the case of a 6-month-old boy with ALHE on his tongue that was treated successfully with oral prednisolone.

Eosinophilic ulcer of the oral mucosa: An update on clinicopathologic features, pathogenesis, and management

Eosinophilic ulcer of the oral mucosa is a benign, reactive, self-limited lesion. Its pathogenesis is unclear, and it clinically manifests as a punched-out ulcer with surrounding indurated border, raising suspicion for a possible malignancy. On histology, an acute and chronic dense inflammatory infiltrate can be appreciated, which can extend to the deep underlying tissue (including skeletal muscle). Eosinophils are especially conspicuous on hematoxylin and eosin staining and might play an important role in the development of the ulcer. Removal of possible triggers followed by monitoring and possible biopsy are among the initial recommendations. Most lesions heal spontaneously without the need for intervention. This review aims at assisting dermatologists to easily recognize this entity, avoiding unnecessary interventions and apprehension.

Traumatic ulcerative granuloma with stromal eosinophilia: A puzzle

Traumatic ulcerative granuloma with stromal eosinophilia (TUGSE) is an ulcerative condition of the oral mucosa amid a chronic course and delayed healing. It is a reactive lesion that usually affects the tongue. TUGSE is a rare mucosal lesion to aid as an ulcer or an indurated submucosal mass and might cause diagnostic problems as it mimics a traumatic or neoplastic ulcer. However, chronic irritation from traumatic agents is well thought out to be a major initiating aspect. Histopathologically, it is categorized by an eosinophilic inflammatory infiltrate penetrating into the underlying muscle. It is significant to make out this mucosal lesion as it mimics malignant ulcers; the condition tends to resolve on its own. Thus, attentiveness of this entity is imperative to emphasize the accurate diagnosis of indurated ulcerated lesions and convey suitable and effective treatment. The present case highlights the clinical aspects, etiopathogenesis and histopathology of this unusual lesion.

Eosinophilic ulcer mimicking malignancy of the lower lip: A case report

Eosinophilic ulcer (EU) is a rare self-limiting chronic benign lesion of the oral mucosa. It is an uncommon and benign disease, which may leading to diagnostic difficulties. Biopsy is recommended to rule out any malignant etiology.

Traumatic ulcerative granuloma with stromal eosinophilia - clinical case report, literature review, and differential diagnosis

Background

Traumatic ulcerative granuloma with stromal eosinophilia (TUGSE) is a rare self-limiting condition of the oral mucosa. The lesion manifests as an isolated ulcer that can be either asymptomatic or associated with mild to severe pain, and in most cases, it affects the tongue. TUGSE lesions may mimic malignancy such as squamous cell carcinoma, CD30 positive lymphoproliferative disorder, or infectious diseases such as primary syphilis, tuberculosis, or Epstein-Barr virus mucocutaneous ulcer. Histologically dominating cells are lymphocytes, histiocytes, and eosinophils.

Case presentation

We describe a TUGSE case of a patient with a solitary ulcer on the lower left retromolar buccal plane. Upon presentation, the patient reported a swelling on the buccal mucosa of the left lower jaw since 1 year with rapid growth over the last days and mild pain while chewing. The diameter of the intraoral lesion on the lower left retromolar buccal plane was approximately 4 × 3 cm; the lesion presented as indurated base with a central superficial ulceration of 2 × 1 cm, indicative for a malignant process. Histologically, the ulceration showed an expanding, infiltrative, and vaguely granulomatous morphology, involving the superficial mucosa and the fatty tissue, and extended between the deep striated muscle fibers. The lesion was rich in lymphocytes, histiocytes, and eosionophils intermingled with activated T-blasts without phenotypic abnormalities. TUGSE was then diagnosed based on the phenotype (especially the lacking expression of CD30, the retained T-cell phenotype, and the absence of Epstein-Barr virus), the clinical presentation, and the morphology. Twenty-six months after diagnosis, no recurrence of the ulceration was seen.

Conclusions

As TUGSE may mimic malignancy or infectious diseases, biopsy is mandatory and should be combined with thorough clinical examination. A screening for infectious diseases (mainly syphilis, Epstein-Barr virus, and HIV infections) must be performed routinely. In most cases, the lesions resolve spontaneously, obviating the need of further actions other than clinical follow-up. The pathogenesis of TUGSE lesions is still under debate, although local traumatic events and a locotypic immune response have been suggested to be major contributing factors.

Self-healing CD30- T-clonal proliferation of the tongue: report of an extremely rare case

Background

The etiology of traumatic ulcerative granulomas with stromal eosinophilia (TUGSE) is not clear, traumatic irritation having advocated as the most likely cause. TUGSEs are typically self-limiting slow-healing lesions of the oral mucosa with unclear pathogenesis, commonly manifesting as a rapidly developing, long-lasting ulcer.

Case presentation

Here we report a controversial case of a self-healing lesion of the tongue in a 57 year-old woman. A clonal T-cell proliferation and CD30 negative immunohistochemical (IHC) profile could be documented.

Discussion and conclusion

In view of the very peculiar clinical and histological features, a retrospective diagnosis of a TUGSE with scarce eosinophilic infiltrate (possibly in regression), displaying CD30- T-clonal proliferation was eventually rendered.

The patient did not report signs of recurrence after a 3-year follow-up period.

Recurrent Oral Eosinophilic Ulcers of the Oral Mucosa. A Case Report

Objective:

This article describes a case of an Oral Eosinophilic Ulcer (OEU) in an otherwise healthy 31-year-old white woman.

Introduction:

The importance of reporting this case was the presence of recurrent episodes with lesions appearing in different areas of the oral mucosa, a type of manifestation not commonly associated with this disease. A typical manifestation of OEU occurs as a single ulceration that goes into healing after an incisional biopsy, a procedure usually required for a proper diagnosis of the disease. In spite of trauma being suggested as the main culprit of OEU, the exact pathogenesis mechanism of this disease remains controversial.

Case report:

The pattern of the present case contradicts the usually common course of the disease, as the patient had experienced many recurrent episodes for almost 2.5 years, with the recurrences occurring even after biopsies performed during some of the relapses. Differential diagnosis included recurrent aphthous stomatitis, recurrent intra-oral herpes, autoimmune disease, Crohn’s disease and malignancy.

Conclusion:

Fortunately, the patient has been free of any recurrences for 1.5 years since the last biopsy was taken at the time she came to our clinic seeking treatment.

Candida is a protractive factor of chronic oral ulcers among usual outpatients

Although many oral ulcers have similar clinical appearances, their etiologies can range from reactive to neoplastic to oral manifestations of dermatological diseases. In patients with an HIV infection, fungal diseases may cause ulceration in the oral cavity; however, there have been few studies of oral ulcerative lesions associated with Candida in patients without an HIV infection. Nevertheless, we encountered chronic oral ulcer associated with Candida among our frequent outpatients without an HIV infection. The present article reviews the causes of oral ulcers, focusing on Candida as a protractive factor for chronic oral ulcers, and it is recommended that Candida involvement be considered in diagnosis of a certain chronic oral ulcer, that remains of unknown origin even if some examinations have been performed.

Eosinophilic ulcer of the tongue masquerading as malignant ulcer: An unexplored distinct pathology

Eosinophilic ulcer (EU) is a rare self-limiting chronic benign ulcerative lesion of the oral mucosa often misdiagnosed as oral malignancy. Its etiopathogenesis is ambiguous, but trauma plays an important role in the development. Microscopically, it is characterized by a polymorphic inflammatory infiltrate with a prominent eosinophilic component and large mononuclear cells extending deep into the submucosa, underlying muscle and salivary glands. We discuss a case of EU in a 55-year-old male, which presented with a symptomatic nonhealing ulcer on the right lateral border of the tongue and was further clinically misdiagnosed as malignant ulcer.

Traumatic Ulcerative Granuloma with Stromal Eosinophila: A Case Report and Review of Pathogenesis

Traumatic Ulcerative Granuloma with Stromal Eosinophilia (TUGSE) is an uncommon condition considered to be a, reactive benign lesion of the oral mucosa, usually affecting the tongue. Its aetiopathogenesis is still uncertain. However, trauma has been found to be a contributing factor in a majority of the cases. Clinically, it often presents as an isolated ulcer or an indurated submucosal mass. Microscopically, it is characterized by a diffuse polymorphic cell infiltrate composed predominantly of eosinophils, B and T lymphocytes, macrophages, and large atypical cells involving the superficial mucosa and extending deep into the submucosa causing degeneration of the underlying muscle. TUGSE is rare and may be easily mistaken for a cancer or microbial infection, but it is self-limiting and tends to resolve spontaneously. Thus, awareness of this entity is important to emphasize the correct diagnosis of indurated ulcerated lesions and deliver appropriate and effective treatment. The present case highlights the clinical aspects, aetiopathogenesis and histopathology of this uncommon lesion.

Oral eosinophilic or traumatic ulcer: A case report and brief review

Eosinophilic ulcer of the oral mucosa is considered to be a benign, reactive, and self-limiting lesion, with unclear pathogenesis, manifesting as a rapidly developing solitary ulcer. We report a case of a 42-year-old man who presented with a chronic indurated ulcer of buccal mucosa adjacent to the right upper wisdom tooth. Histopathological examination showed polymorphic inflammatory infiltrate, rich in eosinophilis, involving the superficial mucosa, and the deeper muscle layer. Immunohistochemical analysis revealed single CD30+ cells scattered within an inflammatory infiltrate. The lesion was excised, and healing was uneventful with no recurrence in more than a year.

Traumatic ulcerative granuloma with stromal eosinophilia - Mystery of pathogenesis revisited

Oral ulcers are a common symptom in clinical practice. Among various causative factors, different types of ulcers in oral cavity exist. Among this, traumatic ulcerative granuloma with stromal eosinophilia (TUGSE) appears to be quite neglected by the clinicians due to the limited knowledge and awareness. On reviewing with a detailed approach to titles and abstracts of articles eliminating duplicates, 40 relevant articles were considered. Randomized studies, review articles, case reports and abstracts were included while conference papers and posters were excluded. Of importance, TUGSE cases been reported only to a minimal extent in the literature. Lack of its awareness tends to lead clinicians to a misconception of cancer. Thus, this particular lesion needs to be differentiated from other malignant lesions to provide a proper mode of treatment. The present article reviews various aspects of the TUGSE with emphasis on the clinical manifestation, pathogenesis, histological, and immunohistochemical study. This study provides the clinician contemporaries, a humble expansion to their knowledge of the disease, based on the searched literature, enabling a more comprehensive management of this rare occurrence.

Solitary extragnathic langerhans cell histiocytosis - a rare case

Langerhans cell histiocytosis (LCH), mainly affects the skull, vertebrae, ribs and mandible in children and the long bones of adults. Symptoms range from none to pain, swelling and tenderness over the site of the lesion. This disease presents oral manifestations which can sometimes be the first expression of the condition. It occurs in three forms namely eosinophilic granuloma in which isolated or multiple bones are involved, But has a good prognosis whereas other variants Hand-Shuller-Christian disease (chronic dessiminated variant) and Letterer-Siwe disease (acute dessiminated form) have poor prognosis. Occasionally only soft tissues are affected without bony involvement. Males are more commonly affected than females. This article describes a rare variant of eosinophilic granuloma of labial mucosa without bony involvement.

Eosinophilic ulcer of the tongue: a rare and confusing clinical entity

Eosinophilic ulcers are rare, benign, reactive and often self-limiting lesions of the oral cavity. Although the aetiology is not clear, trauma is believed to play a role in their development. Clinically, the lesion manifests as an isolated ulcer, with raised, indurated borders and a yellow fibrinous floor; because of its long duration it often leads to the suspicion of squamous cell carcinoma. Although the ulcer is benign in nature, a biopsy is necessary to rule out malignancy. Histopathologically, the ulcer is characterised by the presence of dense inflammatory infiltrate extending into the deeper muscle layers with sheets of lymphocytes intermixed with eosinophils. This is a case report of a 65-year-old woman with an eosinophilic ulcer on the lateral border of the tongue. The ulcer healed rapidly after an incisional biopsy and topical steroid application. The final diagnosis was achieved following clinical and histopathological examination.

The spectrum of primary mucosal CD30-positive T-cell lymphoproliferative disorders of the head and neck

OBJECTIVE

To retrospectively investigate the clinicopathologic spectrum of primary mucosal CD30-positive T-cell lymphoproliferative disorders (PTCLDs) of the head and neck.

STUDY DESIGN

Archives of PTCLDs primarily arising in head and neck mucosa were reviewed. Immunostaining of CD20, CD3, CD4, CD8, CD30, CD56, anaplastic lymphoma kinase (ALK), epithelial membrane antigen (EMA), cytotoxic molecules (TIA-1, granzyme B, or perforin), and Ki67; in situ hybridization for Epstein-Barr virus; and T-cell receptor gene rearrangement analysis were performed.

RESULTS

Fourteen cases of primary mucosal anaplastic large cell lymphoma (M-ALCL) were identified, and no lymphomatoid papulosis (LyP) cases were found. All cases demonstrated atypical mononuclear neoplastic cells with diverse histology and cytomorphology. The typical immunophenotype of neoplastic cells was CD3-positive, CD4-positive, CD8-negative, CD30-positive, ALK-negative, and cytotoxic molecules-positive. Infiltration of inflammatory cells was common. All cases presented an indolent course, regardless of therapy.

CONCLUSIONS

PTCLDs of the head and neck provisionally included M-ALCL alone.

Eosinophilic ulcer of the tongue in an 80-year-old Iranian woman after a psychologically stressful event

Eosinophilic ulcer of the oral mucosa is a benign self-limiting, chronic lesion more frequently seen in the oral cavity or tongue that can mimic squamous cell carcinoma. The pathogenesis of this problem is unknown. In this paper, we present a case of an 80-year-old woman with eosinophilic ulcer of the tongue after a psychologically stressful event.

Concurrent onset of an eosinophilic ulcer of the oral mucosa with peripheral eosinophilia in a human T-cell leukemia virus type I carrier

We present a case of a 46-year-old Japanese woman with an eosinophilic ulcer of the oral mucosa (EUOM), located in the buccal mucosa, who was found by various examinations to be a human T-cell leukemia virus type I (HTLV-1) carrier with peripheral eosinophilia. Her peripheral eosinophilia and EUOM promptly improved in response to oral corticosteroid therapy. EUOM has been described to be possibly associated with trauma, but its etiology has not been fully elucidated to date. In the present case, the presence of peripheral eosinophilia in addition to the EUOM indicated possible influence of certain immune system abnormalities associated with HTLV-1 infection.

Traumatic ulcerative granuloma with stromal eosinophilia of the palate showing an angiocentric/angiodestructive growth pattern

Traumatic ulcerative granuloma with stromal eosinophilia (TUGSE) is a benign, self-limiting lesion of the oral mucosa with unknown pathogenesis. A 65-year-old male patient presented with an ulcerative palate lesion, which on microscopic examination exhibited an exuberant polymorphic lymphoid proliferation, numerous eosinophils, and extensive vascular destruction. The atypical lymphoid cells infiltrating the medium-sized vessels showed positivity for CD3, CD30, and granzyme B, implicating an activated cytotoxic T-cell phenotype. The lesion diagnosed as TUGSE achieved complete resolution within 3 months. This unusual presentation has expanded the spectrum of oral CD30+ T-cell atypical infiltrates and must be distinguished from lymphomas showing angiocentric/angiodestructive growth pattern.

Eosinophilic ulcer: the role of stress-induced psychoneuroimmunologic factors

INTRODUCTION

Eosinophilic ulcer (EU) is a rare pathology and its etiology is still slightly known. It is a benign lesion characterized by fast-growing ulceration with elevated and indurated borders, most commonly affecting the tongue.

CASE REPORT

The authors describe a case of EU on a lingual border that was initiated and had its clinical behavior altered by the psychological stress the patient was experiencing.

DISCUSSION

This paper discusses the stress effects that alter the individual's immunologic response, thus attracting mast cells and eosinophils towards the mucosal epithelium, which are involved in eosinophilic ulcer. The authors make an association between eosinophilic ulcer and atopic dermatitis, two diseases that appear to have a similar, though not fully defined, etiology. The psychological stress factor was considered a predisponent factor for eosinophilic ulcer etiology and its interference in the etiology and evolution of this disease should be considered.

Riga-Fede-like disease in a 70 year old woman

Riga-Fede disease (RFD) describes a benign, ulcerative lesion resulting from the repetitive trauma of contact of the oral mucosal surface of the tongue with the teeth. Although the name applies primarily to small children, similar clinical and histopathological findings can also be found in adults. We describe here a 70 year-old woman showing a painful tongue ulcer with elevated borders and whitish discoloration for the past four years. Repeated histological investigations revealed a benign leukoplakia without dysplasia. Replacement of an ill-fitting prosthesis led to complete remission within two weeks. RDF-like disease is thus a problem in elderly patients for whom topical treatment is insufficient to induce healing.

Traumatic ulcerative granuloma with stromal eosinophilia of the retromolar region

Traumatic ulcerative granuloma with stromal eosinophilia (TUGSE) is a rare chronic benign lesion of the oral mucosa. Clinically, it may mimic squamous cell carcinoma as well as other malignant lesions. Most cases of TUGSE are reactive. A case of TUGSE of the retromolar region is reported. An asymptomatic ulceration with indurated borders, limited to the gingiva, was localized in the right retromolar region. An incisional biopsy was taken. Six weeks after the biopsy, the residual ulceration spontaneously disappeared. After 6 months of follow-up, the lesion had not recurred.Traumatic ulcerative granuloma with stromal eosinophilia can be interpreted as a subset of lymphoproliferative disorders.A malignant lymphoid proliferation should be suspected when atypical histologic findings and monoclonality are observed. Given the benign nature of TUGSE, overtreatment should be prevented in patients affected by this disease.

Localized eosinophilic (Langerhans' cell) granuloma of the lower lip. A lesion that may cause diagnostic error

Eosinophilic (Langerhans' cell) granuloma is most common in children and is unusual in the elderly. A cutaneous lesion as the sole manifestation of adult Langerhans' cell histiocytosis is rare. We report an 81-year-old man who presented with a noduloulcerative lesion on the lower lip. A punch biopsy suggested a lymphoepithelioma-like carcinoma. In the absence of immunohistochemistry, the large pale cells with atypical lobular nuclei and patent nucleoli, with an overlying ulceration, were interpreted as carcinoma cells. Definitive diagnosis was established after complete resection of the lesion aided with the use of immunohistochemistry. The proliferating cells were S100, CD1a and CD207 (langerin) positive and cytokeratin, epithelial membrane antigen, CD15, CD30, melan A and carcinoembryonic antigen negative. To our knowledge, eosinophilic (Langerhans' cell) granuloma of the lip has not been described. The case constituted a diagnostic challenge because of its unusual clinical presentation and its histopathological similarity to certain other benign and malignant entities. Because there was no other organ involved, the patient was treated with complete surgical excision without recurrence or other organ involvement in the 4-month follow-up period. Labial eosinophilic (Langerhans' cell) granuloma should be considered in the histological differential diagnosis in cases with atypical polymorphous infiltrates including large pale cells.
