1/2. Marginal zone B cell lymphomas of Waldeyer's ring--a report of two tonsillectomy cases resembling histomorphological features of inflammatory lesions.We identified two cases of lymphoma of the mucosa-associated lymphoid tissue (MALT) type in 11 tonsillectomy specimens of primary B cell lymphoma of Waldeyer's ring. Both patients were Japanese females presenting with bilateral enlargement of the palatine tonsils. One had a history of chronic otitis media. In that case, the lesion was characterized by an extrafollicular growth pattern with marginal zone-like arrangement. The tumor was mainly composed of medium-sized cells with round or indented nuclei with scant cytoplasm (centrocyte-like cells). In the other patient, most tumor cells were mature plasma cells, plasmacytoid cells, proplasmacytes, and immunoblasts with scattered centrocyte-like cells. tropism of tumor cells for the epithelium was noted in both lesions. Primary marginal zone B cell lymphoma of the MALT type arising from Waldeyer's ring has rarely been reported in the literature, causing certain diagnostic problems. Various florid reactive lymphoproliferative disorders, including chronic tonsillitis and infectious mononucleosis, should be differentiated from this type of primary Waldeyer's ring lymphoma.- - - - - - - - - - ranking = 1keywords = tonsillitis (Clic here for more details about this article) |
2/2. Tuberculous tonsillitis.The epidemiology of tuberculosis has changed recently with an increasing incidence of unusual presentations. A case of tuberculous tonsillitis, which is a rare condition, is presented in this report. The manifestations of this entity are tonsillar hypertrophy and painful ulceration. Final diagnosis of tuberculous tonsillitis is usually made after histopathologic examination of tonsillectomy material. Cultures should be obtained from the tissue specimens, and acid-fast bacilli must be investigated to confirm the diagnosis. Systemic signs of tuberculosis may not be seen in this clinical form. These features may confuse tuberculous tonsillitis with malignancies. In this article, general information and literature about tuberculous tonsillitis are reviewed, and a case of tuberculous tonsillitis is reported to draw attention to this rare clinical form of tuberculosis.- - - - - - - - - - ranking = 9keywords = tonsillitis (Clic here for more details about this article) |
