Uvod: Primarni medijastinalni B krupnoćelijski limfom je redak, visoko agresivan oblik non Hodgkinovog limfoma i javlja se u 5-7 % svih difuznih velikoćelijskih B limfoma i 2% svih non Hodgkinovih limfoma. Vodi poreklo od medularnih ćelija timusa i ima sopstvenu histogenezu. Tipično obolevaju mlade žene u trećoj i četvrtoj dekadi života. Sindrom gornje šuplje vene je prisutan u više od 50% slučajeva, sa otokom lica, ruku, dubokim venskim trombozama, dispnejom, disfagijom, bolom u grudima, glavoboljom i kašljem. Dijagnoza se postavlja patohistološkom i imunohistohemjskom analizom hirurškog bioptata dobijenog medijastinoskopijom. Blagovremena terapija ciklusima monoklonskih antitela i polihemioterapijom omogućava stabilan relaps bolesti. Prikaz bolesnika: Pacijentkinja, stara 37 godina, javlja se prvi put na pregled kod svog izabranog lekara jer je već u nekoliko navrata posećivala Službu hitne medicinske pomoći zbog kašlja, osećaja da je nešto davi, nedostatka vazduha, pritiska i bolova u glavi kao i otečenosti vrata i lica. Započeta detaljna dijagnostika. Radiološki utvrđen tumor medijastinuma, kompjuterizovana tomografija potvrdila i poslata na referentni Institut gde je videoasistiranom torakoskopskom hirurgijom i patohistološkom analizom dijagnostikovan PMBCL CSII AM+. Ordinirano šest ciklusa rituksimab, ciklofosfamid, doksorubicin, vinkristin i prednizolon terapijskog protokola koje je podnela sa očekivanim neželjenim dejstvima. Kontrolna pozitronska emisiona tomografija utvrdila da se tumorska masa u potpunosti povukla. U remisiji je dve godine, dobro se oseća i javlja se na redovne kontrolne preglede. Zaključak: Na izabranom lekaru je velika odgovornost u prepoznavanju ranih simptoma maligne bolesti što ubrzava postavljanje konačne dijagnoze i blagovremeni početak lečenja.

Introduction: Primary mediastinal large B cell lymphoma is a rare highly aggressive form of non-Hodgkin lymphoma and occurs in 5-7% of all diffuse large B lymphoma and 2% of all non-Hodgkin lymphomas. Originates from thymic medullary cells and has its own histogenesis. Typically affects young women in the third and fourth decade of life. Superior vena cava syndrome is present in more than 50% of cases, with swelling of face, hands, deep venous thrombosis, dyspnea, dysphagia, chest pain, headache and cough. Diagnosis is made by histopathological analysis and immunohistochemical surgical biopsy specimens obtained mediastinoscopy. Timely treatment with cycles of monoclonal antibody and chemotherapy is requirement to relapse and stable state.

Case outline: Patient, 37 years old, came for the first time for review at General practice because she has been repeatedly visited emergency service due to coughing, feeling that something is strangling, the lack of air pressure and pain in the head and swelling of face and neck. Started detailed diagnostics. Radiologically determined mediastinal tumor, computed tomography confirmed it and sent to the referral Institute where video-assisted thoracic surgery and patho histology diagnosed PMBCL CSII AM +. Administered six cycles of rituximab, cyclophosphamide, doxorubicin, vincristine and prednisolone therapy protocols submitted by the expected side effects. Control positron emission tomography found that the tumor mass completely withdrawn. In remission for two years, have a good feeling and occurs at regular checkups.

Conclusion: General practice has a big responsibility in recognizing early symptoms of malignant disease that accelerates
the diagnosis and timely start of treatment.
