In case of renal mass, other causes should also be considered. There are some cases reporting an association of renal cell carcinoma with lymphoma in literature. We report a case of relapsed non Hodgkin lymphoma with pulmonary nodular involvement. A 32-year-old woman was admitted in oncology department anterior mediastinal mass and vena cava superior syndrome. Tru-cut biopsy revealed primary mediastinal diffuse large B cell lymphoma. She received six cycles of CHOP chemotherapy regimen followed by involved field radiotherapy. The complete response was achieved. After six months, she complained abdominal pain. The computed tomography demonstrated a mass with 8 cm in diameter and multiple nodules in lung parenchyma. This picture mimicked renal cell carcinoma with pulmonary metastasis. The association between renal cell carcinoma and lymphomas was reported. Although renal involvement of non Hodgkin lymphoma is seen as %50 in autopsy series, antemortem diagnosis is uncommon. Moreover after treatment of lymphoma, risk of renal cancer is elevated. However biopsy was applied from renal mass and established relapse of diffuse large B cell lymphoma. The probability of extranodal relapse of thymic lymphoma should be kept in mind.enCC0 1.0 Universalinfo:eu-repo/semantics/openAccessConference Object2663Q326622
