Primary extranodal marginal zone Bcell lymphoma of hard palate: A case report
نویسندگان
چکیده
Introduction: MALT (mucosa associated lymphoid tissue) lymphomas comprise a heterogeneous group, originally thought to be derived from the marginal zone Bcells that are found surrounding Bcell follicles and within the adjacent lymphoepithelium. They arise most commonly in extranodal organs such as the stomach, major salivary glands and thyroid. Thus, they can be precisely described as extranodal marginal zone Bcell lymphomas (ENMZL). Here, we report a case of MALT lymphoma arising in the palatal minor salivary glands. Case Report: A 55yearold woman presented with two years history of a left posterior palatal mass. Clinical investigations of the case included computed tomography (CT) scan for the assessment of bone destruction and possible intramaxillary extension. Histopathological features and immunohistochemistry findings were consistent with the diagnosis of extranodal marginal zone Bcell lymphoma of MALT type. The lesion was treated by complete surgical excision and followed for two years. Conclusion: Even though oral localization of ENMZL is rare, it should be included in the differential diagnosis of benign appearing swellings of oral cavity.

We report a case of a 75-year old man that came at hematologist’s attention for lymphoma evaluation due to axillary lymph node enlargement and fever. Thorax, abdomen and pelvis Contrast-Enhanced Computed Tomography (CECT) showed lymph nodes, spleen and liver lesions. Axillary lymph node biopsy was performed and the diagnosis of marginal zone lymphoma (MZL) at stage IV was postulated, then the p...

A 61-year-old woman was admitted to our hospital with an ulcerated palate mass and swelling of the right parotid gland. Incisional biopsy from the hard palate revealed an extranodal marginal zone B-cell lymphoma, also called mucosa-associated lymphoid tissue (MALT) lymphoma. Final diagnosis was MALT lymphoma of the parotid gland with concomitant involvement of an extremely seldom site of involv...

Introduction: Extranodal Natural Killer (NK)/T-cell lymphoma (NKTCL) nasal type is a rare but well-known disease with poor prognosis. NKTCL is more prevalent in Asia and comprises about 7-10% of all non-Hodgkin lymphoma cases in this region. The characteristic clinical pattern of NKTCL is the destruction of the midline structures of the mid-face. Case Report: The present study examines a case o...
متن کاملPrimary T cell lymphoma of salivary gland: a report of a case and review of the literature.
Lymphoma of the salivary gland accounts for 5% of cases of extranodal lymphoma and 10% of malignant salivary gland tumours. Most primary salivary gland lymphomas are B marginal zone lymphomas arising on a background of sialadenitis associated with autoimmune disorders such as Sjorgen's syndrome. Primary T cell lymphoma of the salivary gland is rare. This report describes a case of primary T cel...
