Most of these cancers are squamous cell carcinoma and caused by human papillomavirus (HPV) infection. 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 airway was subsequently secured, and the procedure was undertaken. 2005;34:3915. They are covered by stratified squamous nonkeratinized epithelium and contain deep crypts and mucosal glands. Nancy W. Burkhart, EdD, BSDH, AFAAOM, is an adjunct associate professor in the Department of Periodontics-Stomatology, College of Dentistry, Texas A&M University, Dallas, Texas. No progression to malignancy has been reported, although one multisite case within the oral cavity was found to represent MALT-type lymphoma [1]. Cytoplasmic composition also varied between cases, from abundant to scant. Call your doctor or 911 if you think you may have a medical emergency. Normal lymphoid tissue is found in your lymph nodes and tonsils. In addition, rituximab, an anti-CD20 chimeric antibody that has dramatically and favourably improved the survival rate [39], was not added to the therapeutic regimen of this case for some reason. sharing sensitive information, make sure youre on a federal Acta Oncol. This is the first study to report on both HPV and EBV infection status in tongue base lymphoma. [3] Follicular hyperplasia must be distinguished from follicular lymphoma (bcl-2 protein is expressed in neoplastic follicles, but not reactive follicles). Paracortical hyperplasia may be accompanied by vascular proliferation. Bratisl Lek Listy. Formalin-fixed, paraffin-embedded tissue blocks of enrolled cases were used to make three-micrometer-thick sections.

Four treatment response classes were defined, as follows: complete response (CR, 100% resolution); partial response (PR, 50100% resolution); no response (<50% resolution); and progression of disease (PD, tumour enlarged after treatment). The possible reason was that the patient had several high risk factors, such as old age (in his nineties), positivity for c-Myc and P53, and co-expression of c-Myc (50%), Bcl-2 and Bcl-6 [38]. Roentgen examination of the oropharynx and oral cavity. Baran et al.

Review of the preoperative anaesthesia records revealed no features of airway obstruction nor B symptoms on clinical history. Six of the cases exhibited tongue base masses with smooth surface membranes. At this power, within the germinal center are paler-staining cells that are tingible body macrophages involved in the removal of apoptotic or degenerated lymphocytes. SW and XZ did the BCL-2, BCL-6, c-MYC FISH examination. All cases were reviewed and diagnoses were confirmed based on basic morphology, immunohistochemistry staining, and rearrangement.
