Background/Aims: Splenic involvement of tuberculosis, which is rare, warrants better definition in the current era of resurgence of tuberculosis. Methods: Out of 339 splenectomies performed between January 1989 and December 2008 for indications other than trauma, histopathologic analysis of the spleen revealed tuberculosis in 8 patients. Results: All eight patients were referred for splenectomy due to fever of unknown origin (FUO). No patient was infected with HIV, and all had at least moderate splenomegaly and hepatomegaly. Three patients had hypersplenism with bleeding manifestations. Radiologic evaluations demonstrated that splenic lesions were present in five patients. Five patients had evidence of tuberculosis manifested as enlarged splenic hilar lymph nodes, cystic lymph nodes, or liver. Two patients exhibited tubercle bacilli in their sputum during the postoperative period. Conclusions: In areas where tuberculosis is prevalent, tuberculosis should be considered in the differential diagnosis of patients presenting with FUO and splenomegaly. Extrasplenic involvement is usually seen in splenic tuberculosis, although it may not be apparent at presentation. Splenic tuberculosis can present in isolation without extrasplenic involvement, and even in immunocompetent individuals. (Gut Liver 2010;4:94-97)

Background: The genetic landscape of intestinal (INT) and pancreatobiliary (PB) type ampullary cancer (AC) has been evolving with distinct as well as overlapping molecular profiles. Methods: We performed whole-exome sequencing in 37 cases of AC to identify the targetable molecular profiles of INT and PB tumors. Paired tumor-normal sequencing was performed on the HiSeq 2500 Illumina platform. Results: There were 22 INT, 13 PB, and two cases of mixed differentiation of AC that exhibited a total of 1,263 somatic variants in 112 genes (2–257 variants/case) with 183 somatic deleterious variants. INT showed variations in 78 genes (1–31/case), while PB showed variations in 51 genes (1–29/case). Targetable mutations involving one or more major pathways were found in 86.5% of all ACs. Mutations in APC, CTNNB1, SMAD4, KMT2, EPHA, ERBB, and Notch genes were more frequent in INT tumors, while chromatin remodeling complex mutations were frequent in PB tumors. In the major signaling pathways, the phosphoinositide 3-kinase (PI3)/AKT and RAS/mitogen-activated protein kinase (MAPK) pathways were significantly mutated in 70% of cases (82% INT, 46% PB, p = .023), with PI3/AKT mutation being more frequent in INT and RAS/MAPK in PB tumors. Tumor mutation burden was low in both differentiation types, with 1.6/Mb in INT and 0.8/Mb in PB types (p = .217). Conclusions: The exome data suggest that INT types are genetically more unstable than PB and involve mutations in tumor suppressors, oncogenes, transcription factors, and chromatin remodeling genes. The spectra of the genetic profiles of INT and PB types suggested primary targeting of PI3/AKT in INT and RAS/RAF and PI3/AKT pathways in PB carcinomas.
