Polyploid karyotypes in diffuse large B-cell lymphoma (DLBCL) are rare and carry a poor prognosis. Extranodal polyploid lymphoma is uncommon. A 71-year-old man with back pain was found to have ileal intussusception. He underwent surgical resection and was diagnosed with DLBCL with a near-tetraploid karyotype. Despite rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone therapy, he developed recurrent disease for which he started a clinical trial. He then developed dark stools from an ileal ulcer due to progressive disease and died 2 weeks later. This is the first reported case of gastrointestinal DLBCL with polyploidy. These karyotypes require attention to extranodal disease and prompt initiation of therapy.

A 20-year-old female patient was admitted to hospital with complaints of chest and back pain in September 2018. There was a cavitary lesion in the upper zone of the left lung in the chest X-ray. Thorax CT revealed an irregular contoured and shaped mass with 87x67x79 mm sizes, in the upper lobe of the left lung lying to paramediastinal area. Since there was a doubt about malignancy, positron emission tomography (PET) was performed; there was a cavitary lesion in the left upper lobe with high FDG uptake (SUVmax: 23.2). Bronchoscopic examination revealed an endobronchial lesion with nearly complete occlusion in the apicoposterior segment of the left upper lobe. Bronchoalveolar lavage (BAL) performed in this session for acid-fast bacilli (AFB) was negative. The patient was diagnosed as primary pulmonary diffuse large B-cell lymphoma (DLBCL) by histopathological and immunohistochemical evaluation of endobronchial biopsy specimens. Following the final diagnosis of Bronchus-Associated Lymphoid Tissue Lymphoma (BALTOMA), the patient was referred to the department of haematology, and chemotherapy was planned for therapy. Since DLBCL is extremely rare, and uncommonly presenting with an endobronchial lesion, we want to present this patient as the youngest adult case of primary endobronchial BALT lymphoma in the literature.
