Mucosa-associated @entity706 with large cell transformation on the background of XXXX : a case report and review literature.

@entity1 @entity1375 @entity706 @entity2621 @entity1074 @entity1669 @entity1892 @entity6830
Primary @entity706 (PTL) is a rare cause of malignancy that occurs in 0.5% of cases with @entity2621 . The most common subtype is @entity1892 ( @entity1892 ), followed by mucosa-associated lymphoid tissue (MALT) @entity706 . We described the case of a 70-year-old @entity1 who was diagnosed with @entity1074 in the background of @entity1669 with focal area of @entity1892 transformation. The @entity1 was a 70-year-old @entity1 with rapidly growing mass of the thyroid gland with compressive symptom over two months. The laboratory data revealed @entity1375 with positively anti-thyroid antibodies. The computerized tomography scan showed right thyroid mass extended to anterior @entity6830 and compressed adjacent airway with multiple cervical and mediastinal lymphadenopathies. The pathology from incisional biopsy showed extranodal marginal zone @entity1892 of @entity1074 with large cell transformation. The @entity1 received four courses of systemic chemotherapy combined with involved field radiation therapy. The mass was dramatically decreased in size after treatment, leading to a complete resolution of compressive symptoms. @entity706 is quite rare; however the incidence may be higher in @entity1 with @entity2621 . A rapidly growing thyroid gland should be considered as PTL. Chemotherapy and radiation are the mainstays of treatment.
