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. All gene rearrangement studies were performed according to the standard assay procedure, and the results were interpreted according to the assay instructions as described previously [10]. Is it always necessary to carry out a biopsy on lymphoid hyperplasia or is endoscopic examination and MRI enough to decide that it is benign? Some cases of DLBCL may be associated with HPV infection. National Library of Medicine Tumour cell morphologies were different for each case, but all of the tumour cells expressed T cell markers, such as CD3, CD4, and CD8. Leuk Res. or a reactive lymphoid proliferation to an unknown antigenic stimulation [2]. Most DLBCL cases of the tongue base had no Bcl-2, Bcl-6, or c-Myc rearrangement and they were sensitive to rituximab. We thank Violette Ghali, Gina Elhammady, Mark Persky and Songyang Yuan for confirming the pathological diagnosis. Extranodal NHL is complicated; it consists of a group of tumours with different pathological, clinical and prognostic characteristics [6] .Existing series presenting extranodal NHL have mainly summarized the tumours that occur in the head and neck but are not specific to the base of the tongue. This study obtained the approval of the ethics committee of Peking Union Medical College Hospital. Gastroesophageal reflux in bronchial asthma patients.

Mucosa-associated lymphoid tissue lymphoma of the lingual tonsil. This may have been due to the expression of the cytotoxic marker TIA, Granzyme B, and a much higher Ki-67 index (80%), which may indicate a poor prognosis [41]. It has been historically referred to as reactive lymphoid hyperplasia or pseudolymphoma [1]. Oral Surg Oral Med Oral Pathol Oral Radiol. Formalin-fixed, paraffin-embedded tissue blocks of enrolled cases were used to make three-micrometer-thick sections. All authors read and approved the final manuscript.

Non-Hodgkin's lymphoma of the head and neck: a 30-year experience at the University of Florida. These tonsils contain B and T lymphocytes which get activated when harmful bacteria and viruses come in contact with tonsils. Histological features include distention or engorgement of both subcapsular and intraparenchymal sinuses by benign histiocytes which may be hemophagocytic. Chang CC, Liu YC, Cleveland RP, Perkins SL. As both peripheral T cell lymphoma and MCL are extremely rare in the tongue base, we would like to describe these two cases in detail as follows. https://doi.org/10.1016/j.anndiagpath.2005.09.020.

Among our cases, there were 1 GC and 3 NGC cases. Nuclei were counterstained with hematoxylin. Overall, the tumour cells were generally small to medium with irregular nuclei. 2013;119:18327. These results all indicate that HPV positivity does not have much impact on the overall survival of DLBCL patients. 2010;47:846. Pseudotumours of the oropharynx due to muscular contraction. Fluorescence in situ hybridization (FISH) analysis using Break Apart FISH Probes was used to detect BCL2, BCL6 and cMYC gene rearrangements. 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 most common histologic subtype was diffuse large B-cell lymphoma (DLBCL), which occurred in five cases. [1] The growth is termed hyperplasia which may result in enlargement of various tissue including an organ, or cause a cutaneous lesion. HPV RNA ISH all negative. Privacy A poor prognostic case of peripheral T-cell lymphoma in the base of tongue with chemotherapy followed by radiation therapy. 1997;36:41320.

The tumour cells were large and blastic, with a high mitotic rate, which was similar to diffuse large B lymphoma tumour cells. Similarly, the inner cortex has T cells and is called the T-cell zone. Curr Allergy Asthma Rep. 2008 May;8(3):240-4. doi: 10.1007/s11882-008-0040-8. Before The most common histologic subtype was diffuse large B-cell lymphoma (DLBCL), which occurred in five cases.

The data used and/or analysed during the current study are available from the corresponding author on reasonable request. Another reason might be HPV is not transcriptionally active in this patient; the virus integrated into the host DNA and remained inactive. There were two main cytomorphological variants of the DLBCL, NOS cases: centroblastic and immunoblastic. J Oral Maxillofac Pathol. All patients were diagnosed by either biopsy or tumor resection. Russo S, Lo Re G, Galia M, Reginelli A, Lo Greco V, D'Agostino T, La Tona G, Coppolino F, Grassi R, Midiri M, Lagalla R. Radiol Med. It is composed of cortex and medulla. The follicles are cytologically polymorphous, are often polarized, and vary in size and shape. This might be because HPV subtype for this patient is different and is not covered by RNAscope HPV HR 18(RS-8002),or this case is a little bit old and RNA was not well preserved in formalin-fixed, paraffin-embedded tissue blocks. Reported cases involve the conjunctiva, liver, gastrointestinal tract, stomach, lungs, paranasal sinuses, and many cutaneous areas. Immunohistochemical staining was performed using a Ventana Benchmark XT Autostainer (Ventana Medical Systems, Inc., Tucson, AZ). Other features include presence of white spaces and lymphocytes (large cells) within sinuses. Cutaneous lymphoid hyperplasia is generally not malignant, but in rare cases an association has been observed.

Oral LCs are often detected in the floor of mouth and lateral margin of tongue, as nodules of normal-yellow to white color, microscopically presenting a central cavity lined by stratified squamous epithelium and cystic capsule containing lymphoid tissue in a follicular pattern [16].
