Similarly, the inner cortex has T cells and is called the T-cell zone. This patient had a partial response to chemotherapy and died 63months after diagnosis. The tumour cells were large and blastic, with a high mitotic rate, which was similar to diffuse large B lymphoma tumour cells. Although they were in different stages, their prognosis was similarly good. and has since been primarily reported in the skin, breasts, gastrointestinal tract, lungs, and nasopharynx [2]. As stated before, the depth of invasion is a major prognostic indicator. Increasingly, cancers at the base of the tongue are . Generally, MCL patients have a median age of 60years and a striking male predominance [42] .Three of the four cases of MCL including our case, occurred at the base of the tongue. DNA was extracted from paraffin-embedded tissue using standard DNA isolation kits (QIAGEN, 56404). 2000;113:5128. Final pathology was determined on postoperative day (POD) 2 to be benign follicular/intrafollicular lymphoid hyperplasia characterized by polyclonal lymphoid proliferation with an inflammatory background. Most DLBCL cases of the tongue base had no Bcl-2, Bcl-6, or c-Myc rearrangement and they were sensitive to rituximab. Nuclei were counterstained with hematoxylin. Am J Clin Pathol. 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]. Methods We reported a severe case of tongue base BLH compromising the breathing and swallowing of the affected patient. The .gov means its official. Lymphoid hyperplasia of the tongue is a very rare benign lymphoproliferative lesion that closely resembles carcinoma or lymphoma, clinically or histopathologically.

Formalin-fixed, paraffin-embedded tissue blocks of enrolled cases were used to make three-micrometer-thick sections. Three patients are alive with disease and 2 are alive without disease. Do foreign bodies migrate through the body towards the heart? The most common histologic subtype was diffuse large B-cell lymphoma (DLBCL), which occurred in five cases. These lymphoid tissues are controlled by specialized cells that arm themselves to attack and destroy foreign invaderssuch as bacteria, fungi, or virusesthrough phagocytosis or the production of antibodies. Histological features include distention or engorgement of both subcapsular and intraparenchymal sinuses by benign histiocytes which may be hemophagocytic. Only one patient died of the disease.

Mucosa-associated lymphoid tissue lymphoma of the lingual tonsil. 7th ed. The objective of the present study was to identify severe HBT cases and their symptoms and to correlate them with the presence of pharyngolaryngeal signs and esophageal symptoms of gastroesophageal reflux (GER) in patients seen at a laryngology clinic. It is caused by an abnormal proliferation of secondary follicles and occurs principally in the cortex without broaching the lymph node capsule. van der Waal RI, Huijgens PC, van der Valk P, van der Waal I. Characteristics of 40 primary extranodal non-Hodgkin lymphomas of the oral cavity in perspective of the new WHO classification and the international prognostic index. Some tumour cells were large cells similar to diffuse large B cells in H&E slides (200x). One case presented as multiple deep ulcers. 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. Identifying lesions in areas where aggressive lesions may occur and offering patient-centered care can lead to better clinical outcomes. Here we present a literature review and case series of seven patients with NHL of the tongue base. 1970 Dec;8(3):413-24. Our attention is especially drawn to areas where increased gingival growth is uncommon, such as the soft palate, uvula, and posterior oropharynx. Spectrum of a benign entity.
