MALT lenfoma çesitli organlarda ortaya çikan ekstranodal lenfomanin bir türüdür. MALT lenfoma özellikle düsük grade olanlar cerrahi rezeksiyon, radyoterapi ve kemoterapi sonrasi siklikla nüks etme egilimindedir. Bu olgu sunumunda sistemik kemoterapi sonrasi uzun dönemli remisyonla seyreden intestinal MALT lenfoma olgusu sunulmustur. 27 yasinda erkek hasta klinigimize karin agrisi, kilo kaybi ve ates sikayetleri ile basvurdu. Yapilan fizik muayenesinde batinda tüm kadranlarda hassasiyeti mevcuttu. Endoskopik incelemede ise duodenumda nodüler görünüm mevcuttu. Batin tomografisinde sol hipokondriumda barsak duvar kalinlasmasi mevcuttu ve çok sayida mezenterik lenfadenopatisi vardi. Duodenum biyopsisinde lamina propriayi infiltre eden sentrosit benzeri hücreler mevcuttu. B hücre yüzey belirteçlerinden CD20 pozitif saptandi. Helikobakter pylori negatifti. Hastaya düsük dereceli MALT lenfoma tanisi konuldu. 6 kür CHOP kemoterapisi sonrasi 4. yilda hastada klinik, endoskopik, histolojik ve radyolojik remisyon hali mevcuttu. Sonuç olarak düsük grade MALT lenfomada lokalize hastalikta ilk tedavi seçenegi cerrahi olmasina ragmen sadece CHOP kemoterapisi ile bazi vakalarda uzun süreli remisyon saglamak mümkün olabilir.
Mucosa-associated lymphoid tissue lymphoma, as a type of extranodal lymphoma, originates in various organs. Low-grade mucosa-associated lymphoid tissue lymphomas often tend to recur after surgical resection, radiotherapy and chemotherapy. Here, we report a case of intestinal mucosa-associated lymphoid tissue lymphoma with long-term remission after systemic chemotherapy. A 27-year-old male patient admitted to our clinic due to symptoms of abdominal pain, weight loss and fever. Physical examination revealed diffuse tenderness throughout the abdomen. Gastroduodenoscopy revealed nodular lesions in the duodenum. There was a thickened bowel wall in the left hypochondrium with several mesenteric lymphadenopathies on the abdominal tomography. Duodenal biopsy was composed of centrocyte-like cells, with infiltration of the lamina propria, and was positive for B cell surface markers, including CD20. Helicobacter pylori was found to be negative. The diagnosis of low-grade mucosa-associated lymphoid tissue lymphoma was made. The patient has had sustained clinical, endoscopic, histological, and radiological remission for four years after six courses of cyclophosphamide, vincristine, doxorubicin and prednisone chemotherapy. In conclusion, although surgery is the first-line therapy in localized low-grade mucosa-associated lymphoid tissue lymphoma, it may be possible to induce long-term remission with cyclophoshamide, vincristine, doxorubicin and prednisone chemotherapy alone.
