Laryngeal lymphoma derived from mucosa-associated lymphoid tissue

Extranodal marginal zone lymphoma of the larynx: A case report and scoping review

BACKGROUND

This scoping review aims to review cases of extranodal marginal zone lymphoma (MZL) of the larynx to establish best management practices for this rare clinical entity.

METHODS

In this paper, we report a case of laryngeal MZL, in accordance with CARE guidelines. We then performed a scoping review according to PRISMA-ScR criteria of published cases of MZL involving the larynx. The following data were collected for each case: age, sex, size, location(s) involved, stage, treatment, follow-up, and recurrence duration.

RESULTS

Sixty-six patients with laryngeal MZL, first reported in 1990, were identified. Characterized by its low-grade histological appearance and indolent course, laryngeal MZL is generally confined to the larynx and has an excellent prognosis with radiation used as first-line therapy.

CONCLUSIONS

It is imperative for clinicians to consider lymphoma in the differential diagnosis of a laryngeal tumor from any subsite, as certain pathologies may carry high risks of metastasis.

A Rare Case of Laryngeal Mantle Cell Lymphoma

This case report describes an 80-year-old woman presenting to her primary care practitioner after several months of a persistent globus sensation and throat fullness.

Laryngotracheal Stenosis Secondary to Mantle Cell Lymphoma

Acute laryngeal dyspnea is a life-threatening emergency often attributed to laryngeal tumors or inflammatory edema in adults. Primary laryngeal lymphomas are especially infrequent. As an aggressive subtype of B-cell non-Hodgkin lymphoma (NHL), mantle cell lymphoma (MCL) cases are particularly complex.  Herein, we present a case of laryngotracheal stenosis secondary to primary MCL. A comprehensive assessment, including in-office flexible laryngoscopy, revealed distinct findings within the supraglottis and subglottis. In the supraglottis, a submucosal lesion with well-defined, rounded edges was observed, while the subglottis exhibited a friable tumor occupying approximately 90% of the airway. This necessitated immediate intervention, leading to microlaryngoscopy, biopsy, and open tracheostomy. Due to the rarity of primary laryngeal lymphomas, they present a significant diagnostic challenge. Timely diagnosis is crucial to enable tailored therapeutic strategies and improved patient outcomes. This case highlights the importance of considering lymphomatous etiologies in the management of laryngotracheal stenosis and emphasizes the need for a multidisciplinary approach to optimize patient care.

Non-Squamous Cell Carcinoma of the Larynx: A State-of-the-Art Review

(1) Background: Non-squamous cell laryngeal carcinoma includes endothelial tumors, such as minor salivary gland tumors, lymphoepithelial tumors, neuroendocrine tumors, soft and hard tissue sarcomas, and malignant melanomas. (2) Methods: A state-of-the-art review using the MEDLINE/PUBMED, Google Scholar, Ovid Medline, Embase, and Scopus electronic databases was performed. (3) Conclusions: In order to optimize overall treatment outcomes, a multidisciplinary, patient-centered approach to the management of non-SCC of the larynx must be adopted universally; a national or international registry on non-SCC laryngeal cancer can be useful to improve understanding about the behavior of this kind of tumor.

Primary laryngeal T-cell lymphoma: A case report and review of the literature

•

Primary lymphoma of the larynx is extremely rare, representing less than 1% of all primary laryngeal neoplasms which consists mainly of non-Hodgkin lymphomas.

•

Diagnosis requires immunohistopathological examination of the laryngeal mass.

•

The clinicopathological characteristics and rational treatment of primary laryngeal lymphoma are still unclear and need to be further defined due to the paucity of this pathology.

Introduction

Primary lymphoma of the larynx is extremely rare, representing less than 1% of all primary laryngeal neoplasms. It consists mainly of non-Hodgkin lymphomas (NHLs), represented particularly by diffuse large B-cell. Extranodal natural killer/T-cell lymphoma, presented in larynx is a rare condition that accounts for less than 11% of all lymphomas without distinctive clinicopathologic features, as well as challenging pathologic diagnosis.

Case report

We report here a case of a 64-years-old man who presented with primary lymphoma type T of the subglottic larynx. A histopathological examination of the biopsy confirmed non-Hodgkin T cell lymphoma. Given his age, he underwent chemotherapy and radiation therapy. The patient was disease-free after 18 months follow up.

Conclusion

The clinicopathological characteristics and rational treatment of primary laryngeal lymphoma are still unclear and need to be further defined due to the paucity of this pathology.

Primary laryngeal lymphoma in China: a retrospective study of the last 25 years

OBJECTIVE

To retrospectively study the primary laryngeal lymphoma cases in China reported in Chinese-language literature.

METHOD

Chinese-language literature was searched for papers on primary laryngeal lymphoma published in the last 25 years.

RESULTS

The selected papers comprised a total of 115 cases. The male-to-female ratio was 3.4:1. Non-Hodgkin's lymphoma was the exclusive pathological type. The estimated 3-year, 5-year and 10-year survival rates were 70.9 ± 6.4 per cent, 63.4 ± 7.6 per cent and 56.4 ± 9.5 per cent respectively, as determined by Kaplan-Meier analysis. B-cell non-Hodgkin's lymphoma patients had a better prognosis than T-cell non-Hodgkin's lymphoma patients (p = 0.032). Patients with lymph node involvement at diagnosis had a poorer prognosis (p < 0.01).

CONCLUSION

Primary laryngeal lymphoma is a rare disease with no specific clinical features. More than one biopsy might be needed to obtain the correct diagnosis. Proper treatment could lead to promising outcomes. The T-cell subtype and lymph node involvement at diagnosis might indicate worse prognosis.

Subglotic malt-lymphoma of the larynx: an unusual presentation of chronic cough

Extranodal non-Hodgkin lymphomas limited to the larynx are rare, accounting for less than 1% of all laryngeal neoplasms. The most common site of development of primary laryngeal lymphomas is the supraglottic region. In most cases, the presenting symptoms are hoarseness, dysphagia, dyspnea, and cervical lymphadenopathy. They consist mainly of non-Hodgkin lymphoma, especially of diffuse large B-cell lymphoma and mucosa-associated lymphoid tissue. We report a case of a primary extranodal marginal zone of mucosa-associated lymphoid tissue (Malt Lymphoma) of the larynx in a 73-year-old non-smoker woman, presented as chronic cough, unresponsive to oral corticosteroid. We present a detailed report of her clinical and paraclinical data as well as treatment options. In patients with chronic cough, uncommon causes should be considered when the cough persists after evaluation for common causes. If a cough persists after consideration of the most common causes, CT scan and a bronchoscopic evaluation are fundamental for the diagnosis of tumors of the upper and lower respiratory tract.

18F-fluorodeoxyglucose positron emission tomography/computed tomography findings in mucosa-associated lymphoid tissue lymphoma of the larynx: a case report and literature review

Laryngeal mucosa-associated lymphoid tissue (MALT) lymphoma is rare, with only 25 cases reported in the literature. This report presents a case of laryngeal MALT lymphoma in a 35-year-old female with a 6-year history of progressively worsening hoarseness. MALT lymphoma was diagnosed based on biopsy and immunohistochemical analysis. The patient received two cycles of cyclophosphamide + epirubicin + vincristine + prednisone (CHOP) chemo therapy, which was ineffective. (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT) showed (18)F-FDG accumulation in the larynx only and identified stage IE lymphoma. CHOP chemotherapy was terminated and the patient was treated with radiotherapy. After 3 months (total radiation dose 27 Gy), (18)F-FDG PET/CT scan showed that the laryngeal lesion was in complete remission. A review of the literature on the MEDLINE(®)/PubMed(®) databases regarding laryngeal MALT lymphoma and the use of PET/CT found that radiotherapy is the first-line treatment for stage I and II MALT lymphoma.

Mantle cell lymphoma of the larynx: Primary case report

INTRODUCTION

Primary laryngeal lymphomas are exceedingly rare. Only about a hundred cases have been reported. They consist mainly of non-Hodgkin lymphoma, especially of diffuse large B-cell lymphoma and mucosa-associated lymphoid tissue. We report the first case of a primary laryngeal mantle cell lymphoma.

CASE PRESENTATION

We report a case of a primary mantle cell lymphoma of the larynx in a 70-year-old North African non-smoker male. We present a detailed report of his clinical and paraclinical data as well as treatment options.

CONCLUSIONS

Mantle cell lymphoma is a very aggressive lymphoma subset associated with poor prognosis. Laryngeal mantle cell lymphoma is exceedingly rare. To the best of our knowledge, this is the first case to ever be reported.

Clinical study of mucosa-associated lymphoid tissue lymphomas of the head and neck

BACKGROUND

Limited information is available on mucosa-associated lymphoid tissue lymphomas arising in the head and neck.

METHOD

A retrospective analysis was conducted of 20 patients who were histologically diagnosed with mucosa-associated lymphoid tissue lymphoma and treated at our institution between January 1990 and December 2009.

RESULTS

Treatment consisted of surgical resection alone in two patients (10 per cent), surgical resection with consecutive radiotherapy in one (5 per cent), and radiotherapy alone in eight (40 per cent). Three patients (15 per cent) were treated with systemic chemotherapy, and three (15 per cent) received chemoradiotherapy. Three patients (15 per cent) were informed of the diagnosis but not treated for their condition.

CONCLUSION

All of the 20 patients were still alive after a mean follow-up period of 50.8 months. Local treatment for mucosa-associated lymphoid tissue lymphoma of the head and neck should be the first choice in early-stage disease. However, prolonged follow up is important to determine these patients' long-term response to treatment.

Primary laryngeal lymphoma: report of 3 cases and review of the literature

BACKGROUND

Extranodal lymphomas limited to the larynx are rare, accounting for less than 1% of all laryngeal neoplasms. The aim of this study was to report the experience of our department in the management of these aggressive lesions, as they require special diagnostic and therapeutic attention.

METHODS

The case records of 3 patients with the diagnosis of lymphoma involving the larynx were retrospectively reviewed.

RESULTS

The histopathological diagnosis revealed 1 case of marginal zone lymphoma mucosa-associated lymphoid tissue type, 1 case of T-lymphoblastic lymphoma, and 1 case of a rare coexistence of in situ squamous cell carcinoma with an isolated intravascular (angioimmunoblastic) lymphoma of peripheral T-cell origin. Details of the presentation, diagnostic procedures, treatment, and outcome of these patients were presented.

CONCLUSIONS

Primary laryngeal lymphoma is a rare entity. Early symptoms are subtle and nonspecific, and confirmation of the diagnosis is often difficult. Because of the rarity of this tumor type, the optimal management remains controversial and it seems that should be managed not as a distinct disease entity but as an unusual presentation of non-Hodgkin lymphoma, according to the recent treatment trends.

Primary mucosa-associated lymphoid tissue (MALT) lymphoma of the larynx

BACKGROUND

Mucosa-associated lymphoid tissue (MALT) lymphoma is usually associated with a chronic inflammatory disease from which lymphoid tissue of MALT type arises as a prerequisite for lymphoma proliferation. No well-characterized chronic inflammatory process has been identified in the larynx.

METHODS

We report a case of primary MALT lymphoma of the larynx associated with extraesophageal reflux, chronic laryngitis, and gastric Helicobacter pylori infection, raising the issue of its physiopathology and treatment.

RESULTS

Treatment of this MALT lymphoma of the larynx consisted of complete surgical excision associated with omeprazole, amoxicillin, and clarithromycin. No evidence of disease was observed after 24 months of follow-up.

CONCLUSIONS

We may assume that chronic laryngitis could be a precursor to MALT lymphoma. This case is the first one to our knowledge of a primary MALT lymphoma of the larynx treated with conservative management combining surgical excision, reflux therapy, and eradication of gastric H. pylori infection.

Extranodal non-Hodgkins lymphoma of larynx

Non-Hodgkins lymphoma is found in the older age group with extranoda involvement more commonly seen than in Hodgkins lymphomna. It isusually of B-cell type which has a better prognosis than T-cell type, Extranodal Non-Hodkin's lymphomas of larynx are rare. they can present as isolated lesions in larynx or associated with multiple involvement. They are usually found in the supraglottic region of the larynx. We present a case of 70-year-old female with extranodal Hodgkins lymphoma of epiglottis with metastasis in the liver.

[Report of a case: non-Hodgkin's lymphoma of the hypopharynx in a patient with HIV infection. Remission without lymphoma-specific treatment]

Non-Hodgkin's lymphomas (NHL) are common in HIV patients, although it is rare for primary lymphomas to develop in the larynx or hypopharynx. We present the case of a patient that was diagnosed of a high degree NHL, following a biopsy of the piriform sinus' lesion, taker by direct laryngoscopy. Simultaneously he was diagnosed as HIV. The interest of this paper is the total remission of the lymphoma seen after specific HIV treatment only.

Region-specific immunological response of the different laryngeal compartments: significance of larynx-associated lymphoid tissue

The occurrence of primary extranodal marginal-zone B-cell lymphoma [of the mucosa-associated lymphoid tissue (MALT) type] has only been described in the supraglottic region, implying that preexistent organized lymphoid tissue is present at that site only. To date, studies have not established clearly whether organized MALT shows a site-related distribution in the larynx. The supraglottic region of the false vocal folds and the subglottis from 87 unselected cadavers with no known history of nasal, oral, pharyngeal, laryngeal, tracheal, or esophageal disease were examined for the presence of organized MALT. Organized lymphoid tissue was found with the cytomorphological and immunophenotypic features of MALT in 100% of false vocal folds of children and in more than 90% of adolescents, decreasing to 7.1% in persons in their sixth decade, whereas MALT was completely absent in the subglottis in all age groups. The results explain why primary extranodal marginal-zone B-cell lymphoma has only been described in the supraglottic region but is absent in the subglottis. Moreover, the results suggest a region-specific immunological response of the different laryngeal areas as reflected in clinical observations and animal studies. However, the impact on presence or absence of laryngeal MALT awaits clarification.

[Subglottic MALT-type lymphoma: unusual location]

We report a case of a 79-year-old woman presenting subglottic tumor whose hystopathological study was MALT-type lymphoma. After excluding the possibility of systemic dissemination, local radiotherapy treatment was applied. The interest of this study lies in the rare involvement of haematopoietic neoplasms in the larynx, especially the MALT-type in subglottic location. We review the literature on this subject, exposing the clinical, therapeutical and follow up data in respect to the initial location of the lymphoma.

Mucosa-associated lymphoid tissue lymphoma with initial supradiaphragmatic presentation: natural history and patterns of disease progression

PURPOSE

Mucosa-associated lymphoid tissue (MALT) lymphoma commonly presents in the gastrointestinal (GI) tract. Supradiaphragmatic MALT lymphoma is less common and its natural history is not well defined. This study was conducted to understand the natural history, to determine the frequency of synchronous disease in the GI tract, and to understand the patterns of disease progression after treatment for supradiaphragmatic MALT lymphoma.

PATIENTS AND METHODS

We retrospectively reviewed the medical records of 39 patients who presented with supradiaphragmatic MALT lymphoma between 1991 and 1997.

RESULTS

The median age of patients was 58 years (range, 25-90 years) with 16 male and 23 female patients. The most common primary site was salivary gland followed by ocular adnexa, lung, oral cavity, and others. Sixteen patients underwent esophagogastroduodenoscopy and biopsy (EGD + Bx) and 4 were found to have gastric involvement. Ann Arbor stages were the following: IEA, 17; IIEA, 5, IIEB, 1; and IVA, 16. The initial treatments were: involved field radiation therapy (n = 10), chemotherapy (n = 14), combination of radiation therapy and chemotherapy (n = 9), observation after biopsy (n = 4), antibiotics only (n = 1), and patient refusal of further intervention (n = 1). Seven patients received antibiotics as a part of the initial treatment. Every patient except for 1 was alive at a median follow-up of 39.5 months (range, 3-83 months). Thirty-six patients achieved complete response (CR) to the initial treatment. The actuarial 5-year progression-free survival rate was 83%. Progression of the disease occurred in 4 patients, with 2 in the stomach. Salvage attempts were made to 4 and were successful in 3. Of the 2 patients who relapsed in the stomach, 1 had negative EGD + Bx at the time of initial diagnosis. An EGD + Bx was not done in the second patient.

CONCLUSION

Supradiaphragmatic MALT lymphoma appears to have a favorable prognosis. However, routine evaluation of the stomach is recommended for patients who present with supradiaphragmatic MALT lymphoma at the time of initial evaluation and at the time of relapse. Patients who failed initial therapy can be successfully salvaged with further treatment.

Low-grade MALT lymphoma of the stomach: a review of treatment options

PURPOSE

Low-grade mucosa-associated lymphoid tissue (MALT) lymphoma of the stomach (MLS) is often associated with the presence of Helicobacter pylori (H. pylori) bacteria. Eradication of the infection with antibiotic therapy may result in regression of the lymphoma. But when antibiotic treatment fails to reverse the malignant process or if H. pylori is absent, other treatment options should be considered. Because MLS is often confined to the stomach and regional lymph nodes, it is potentially curable with local therapy. Endoscopy and improved imaging, with endoscopic ultrasound (EUS) and computerized tomography (CT), have reduced the prior dependence on surgery for diagnosis and staging of gastric lymphomas.

METHODS AND RESULTS

This review details the advances in the diagnosis, classification, and imaging of MLS. We also describe the experience that supports the use of radiation therapy as the preferred treatment of MLS in patients who have not responded to antibiotic therapy or have not had evidence for H. pylori infection.

CONCLUSIONS

Radiation therapy for MLS is not only effective and safe, but offers the significant advantage of low morbidity and gastric function preservation.

Clinical and pathologic characterization of mucosa-associated lymphoid tissue lymphoma of the head and neck

Mucosa-associated lymphoid tissue (MALT) has recently been recognized as a possible site of origin for low-grade lymphomas of the B-cell type. Though relatively rare, these MALT lymphomas may arise within several sites in the head and neck, and often present diagnostic and therapeutic challenges. We review 4 cases of primary MALT lymphoma of the head and neck, treated with surgical excision (3 cases), irradiation (2 cases), and chemotherapy (1 case), to further characterize this new subtype of head and neck malignancy. The mean time from onset of symptoms to histologic diagnosis was 15 months. Fine needle aspiration identified an atypical lymphoid infiltrate in only 1 of 3 patients. Immunohistochemical analysis was essential in establishing the diagnosis of MALT lymphoma in all 4 of the cases, and demonstrated characteristic negative staining for CD3, CD5, and CD43, positive staining for CD20, and monotypic staining for either kappa or lambda light chain immunoglobulin markers. All patients achieved complete remission after primary therapy, and all remain free of disease with follow-up ranging from 6 to 54 months (mean 33 months). The diagnosis of MALT lymphoma should be considered in cases of atypical lymphoid infiltrates in the head and neck, and increased awareness coupled with detailed immunohistochemical analysis is essential to securing an accurate diagnosis. Clinical remission of MALT lymphoma may be achieved with several modalities, but further study will be required to determine the long-term response to treatment.
