Nasopharyngeal Malt Lymphoma- A Case Report Of Rare Entity With Review Of Literature

摘要

Mucosa associated lymphoid tissue confers the first line of defense in case of membranes which are directly exposed to the external environment. MALT lymphomas arising at these sites present diagnostic and therapeutic challenges, especially if arising from areas such as the nasopharynx, where adenoid hyperplasia is very commonly present as a mass. In the present case report, a 55 year old male presented to the medical emergency department with complaints of severe respiratory distress. Radiological and clinical evaluation revealed a mass; the biopsy was taken and sent for histopathological examination, which suggested a possibility of MALT lymphoma. This was subsequently proven on immunohistochemical studies, which showed positive staining for CD 20 and negative staining for CD 3, CD 5 and CD 43. Hence, a final diagnosis of low grade B-cell MALT lymphoma was made. A quick and comprehensive diagnosis of MALToma is desirable, as it is amenable to chemotherapeutic therapy.
