Except in one case, all patients exhibited a tongue base mass with smooth and intact membrane surface. Content on HealthTap (including answers) should not be used for medical advice, diagnosis, or treatment, and interactions on HealthTap do not create a doctor-patient relationship. A final diagnosis was made through deep resection. Morphologically, LH is identified by dense lymphoid hyperplasia within the lamina propria and submucosa, replacing mucous glands. Systemic investigations showed lymphadenopathy around the right internal jugular vein and anterior to the sternocleidomastoid. The lymphoid follicles at the base of the tongue can be detected when examining the pharynx of adults, but the presence of large follicles, denoted "severe" hypertrophy of the base of the tongue (HBT) is rare. Understanding the biological behavior of and therapeutic options for tongue lymphoma is difficult due to the paucity of cases. Lymphoid hyperplasia of the tongue is a very rare benign lymphoproliferative lesion that closely resembles carcinoma or lymphoma, clinically or histopathologically. [36] showed that patients with DLBCL located on Waldeyers ring (base of the tongue) often have a better prognosis than nodal DLBCL patients. The diagnosis of FLH is of clinical importance as it may be confused with malignant lymphoma, both on clinical examination and histopathology. It is composed of cortex and medulla. The biopsy showed recurrence, with bone marrow involvement. volume15, Articlenumber:30 (2020) Acta Oncol. By using this website, you agree to our HIV serology was negative.

The tongue has a rich network of lymphatics that drain to neck levels I-III, which is the usual pattern of spread when these tumors metastasize. Lymphoma is the second most common primary malignancy occurring in the head and neck behind squamous cell carcinoma, while NHL accounts for 6590% of all lymphomas occurring in the head and neck [1, 2] .2030% of NHLs are derived from extra-nodal sites [3] .Nonetheless, NHL with a primary site in the oral cavity is rare, and in the tongue base, even rarer [4, 5].

A lymphoid follicle under microscope is shown in Figure 2. It provides context as to what an oral pathologist might see that aides in excludingnonreactive or neoplastic lesions. While the etiology is poorly understood, a number of previous theories exist, which are included here in the context of a literature review. Curr Top Microbiol Immunol. Call your doctor or 911 if you think you may have a medical emergency. The complaints due to severe HBT were noisy respiration, hoarseness, throat clearing, dry cough, globus pharyngeus, and nasal voice. Does lymphoid hyperplasia and Lymphoma looks the same and is there a threatment for oral Lymphoid Hyperplasia? Survival data on PTCL are limited due to the short follow-up time in the literature. Human papillomavirus (HPV) and Epstein-Barr virus (EBV) are important aetiological risk factors for tumours of the head and neck. https://doi.org/10.1016/j.ijom.2010.03.029. Two pathologists interpreted the FISH results using an Olympus fluorescence microscope equipped with 100 objective lens and orange/ green/4, 6-diamid-ino-2-phenylindole filters.

All authors read and approved the final manuscript. Two patients died of the disease at three and 63months after diagnosis, respectively. Here we present a literature review and case series of seven patients with NHL of the tongue base. Mitosis could be observed easily. Methods We reported a severe case of tongue base BLH compromising the breathing and swallowing of the affected patient. Regezi JA, Sciubba JJ, Jordan RCK. In our case, the late stage of disease, the morphologically blastic variant [44], and involvement of neck lymph nodes were all factors that contributed to poor prognosis of this patient.

The HPV subtype that often infected the cervix, were active but doesnt do much harm to the host because the oral area was not the best breeding site for the virus. Clinicopathological information including age, gender, tumour location, histological subtype, grading, staging, survival, and response to treatment was acquired from the archives. https://doi.org/10.1053/ajot.2000.8382. Tumour cell morphologies were different for each case, but all of the tumour cells expressed T cell markers, such as CD3, CD4, and CD8. ZL, BW, XR and YC reviewed all the cases together. The prognosis for MCL seems to be poorer than that for DLBCL at the base of the tongue. 2008;88:2068. 2000;21:2716. Federal government websites often end in .gov or .mil. Benign lymphoid hyperplasia is a benign proliferation of lymphoid tissue in response to external irritation and occurrence within oral cavity is rare. https://doi.org/10.1200/JCO.2005.07.155.

Immunohistochemistry was negative for lymphoma. Imaging and pathological findings of PTCL (case 3). This is because reactive growth of lymphoid tissue can be difficult to distinguish from the most serious neoplastic lesions.1. One patient in the literature died 18months after diagnosis despite being in an early stage. Lopez-Guillermo et al. Severe benign LH is unusual in the head and neck region, but the diagnosis should be entertained on the part of the clinician both clinically and histologically when lymphoma is suspectedparticularly in the oral cavity. Expression and alteration of p16 in diffuse large B cell lymphoma. 353358, 2001. These results all indicate that HPV positivity does not have much impact on the overall survival of DLBCL patients. Three reactive samples, either tonsils or lymph nodes, were included to establish cut-off values. Four were staged at III and IV and had higher IPI scores (2 or 3).

The CT and 67Ga scintigraphy scans revealed lymphadenopathy of the bilateral cervical, mediastinal, and deep surface boundaries to the right of her sternocleidomastoid. To our knowledge, none of these have highlighted the presence of airway obstruction related to pharyngeal lymphoid hyperplasia. Am J Gastroenterol. 5760, 1993. 1, pp. P16 stains the nucleolus and cytoplasm. Imaging showed a well-bordered cystic mass (2cm in diameter) at the right base of the tongue that extended into the pharynx, and so a biopsy was performed. Squamous cell hyperplasia is characterized by increased cell numbers, which usually results in increased thickness of the squamous epithelium. For T cell receptor rearrangement, the IdentiClone TCRB, TCRG, and TCRD Gene Clonality Assays were used with gel detection (InVivoScribe Technologies, San Diego, CA, USA).

A woman in her fourth decade was admitted with a one-month history of pharyngeal foreign body sensation. Had biopsy on axillary lymph node. A mass was found through radiological and laryngoscopic examinations in six patients. DNA was extracted from paraffin-embedded tissue using standard DNA isolation kits (QIAGEN, 56404). For DNA detection of high-riskin situ HPV infection, biotin-labelled HPV probe solutions (Leica, Newcastle, UK) were added to formalin-fixed, paraffin-embedded tissue sections.

The follicles are cytologically polymorphous, are often polarized, and vary in size and shape. Lymphoid hyperplasia at the base of the tongue. In summary, NHLs in the base of the tongue are rare with nonspecific symptoms of oropharyngeal discomfort, and they could present with normal-like mucosal surfaces.

Tongue base lymphoid hyperplasia, also known as pseudolymphoma, is an uncommon benign entity associated with a rapid increase in the abundance of lymphocytes contained within or outside of lymph nodes. Reported cases involve the conjunctiva, liver, gastrointestinal tract, stomach, lungs, paranasal sinuses, and many cutaneous areas. Benign Lymphoid Hyperplasia of the Tongue Base Causing Upper Airway Obstruction Severe benign lymphoid hyperplasia (LH) is unusual in the head and neck region, but the diagnosis of LH is of clinical importance as it may be confused with malignant lymphoma, both on clinical examination and pathologically.

The role of EBV in the pathogenesis of diffuse large B cell lymphoma. 2007;86:35660. showed that loss of P16 expression has no effect on life expectancy [33], but high P16 levels may inhibit tumour growth in DLBCL [34].

Article While an association with bacterial infection has not been clearly identified, one aggressive case of FLH has been linked to the presence of Epstein-Barr virus, causing clonal arrangement (expansion) in the local tissue DNA [4].
