Here we report a 48-year-old male with FA-DLBCL who experienced recurrence within one year from initial presentation. The patient had a history of an abdominal aortic aneurism and underwent an endovascular aneurysm repair (EVAR) in 2013. Later in 2019, he was found by CT aortogram to have endoleak of the aneurysm repair. He underwent an open abdominal aortic aneurysm repair with explant of the endovascular stent. The explanted graft was sent to pathology and was found on gross examination to have ample adherent tissue. On microscopic examination this tissue was composed of abundant fibrinous material with several foci of large pleomorphic lymphocytes with enlarged round to polyhedral nuclei, prominent nucleoli, open chromatin, and scanty cytoplasm. Necrosis was also seen in a largest focus of tumor infiltrate. By immunohistochemistry, the atypical, large lymphocytes expressed CD20 and MUM-1; and positive for EBV, by Epstein-Barr virus (EBV) in situ hybridization (EBER-ISH). Together, the diagnosis for FA-DLBCL was made. Further work up by PET scan showed no active disease. The patient re-presented 10 months later with right lower extremity ischemia due to the vascular graft thrombosis. The thrombectomy specimen showed identical findings of his initial FA- DLBCL. Here we discuss the clinicopathologic findings of this entity and the importance of clinical follow up.</p></div>","PeriodicalId":38075,"journal":{"name":"Human Pathology: Case Reports","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.ehpc.2021.200538","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49386077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Characteristically, patients present with the clinical triad of nail dystrophy, oral leukoplakia, and skin pigmentation defects, but the disease involves degenerative changes in multiple organs. Mutations in telomere-binding proteins such as TINF2 (TRF1-interacting nuclear factor 2) or in telomerase, the enzyme that counteracts age related telomere shortening, are causative in dyskeratosis congenita. We present a patient who presented with severe hypoxemia at age 13. The patient had a history of myelodysplastic syndrome treated with bone marrow transplant at the age of 5. At age 18 she was hospitalized for an acute pneumonia progressing to respiratory failure, developed renal failure and ultimately, she and her family opted to withdraw support as she was not a candidate for a lung transplant. Sequencing of the patient’s TINF2 locus revealed a heterozygous mutation (c.844C > T, Arg282Cys) which has previously been reported in a subset of dyskeratosis congenita patients. Tissue sections from multiple organs showed degenerative changes including disorganized bone remodeling, diffuse alveolar damage and small vessel proliferation in the lung, and hyperkeratosis with hyperpigmentation of the skin. Autopsy samples revealed a bimodal distribution of telomere length, with telomeres from donor hematopoietic tissues being an age-appropriate length and those from patient tissues showing pathogenic shortening, with the shortest telomeres in lung, liver, and kidney. We report for the first time a survey of degenerative changes and telomere lengths in multiple organs in a patient with dyskeratosis congenita.</p></div>","PeriodicalId":38075,"journal":{"name":"Human Pathology: Case Reports","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.ehpc.2021.200517","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9632901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, serum tumor markers were within the normal limit (CA 19–9, CEA, AFP, and βHCG). Subsequently, he underwent a biopsy of the peritoneal nodules. Biopsy showed a proliferation of epithelioid/round cells with ample cytoplasm and occasional vacuoles, displaying papillary architecture. Immunohistochemistry showed tumor cells were strongly and diffusely positive for WT1, AE1/3, CK7, CK20, desmin, and CD99, focally positive for calretinin, D2-40, and CK5/6, while negative for BerEp4, MOC-31, trypsin, TTF-1, P40, GATA3, CDX2, and PAX8.
