- Alterations of BRAF, most commonly the V600E point mutation, are uncommon in salivary gland tumors, while BRAF fusions are exceptionally rare. We report four salivary gland tumors harboring BRAF fusions. The cohort included three males and one female aged 30-67 years (median, 46 years), all with tumors arising in the parotid gland. Two tumors were classified as intraductal carcinoma of oncocytic and mixed oncocytic-intercalated duct subtype, harboring AGK::BRAF and PAPSS1::BRAF fusions. In both cases, tumor cells were positive for S100, SOX10, and mammaglobin, and negative for androgen receptor. One tumor was diagnosed as low-grade acinic cell carcinoma with an SND1::BRAF fusion; tumor cells expressed SOX10, DOG1, and NR4A2 (Nurr1), but were negative for S100 and NOR1. The fourth tumor, classified as high-grade salivary adenocarcinoma, not otherwise specified, harbored an AGK::BRAF fusion and showed unusual morphology, including monolayered tubules and trabeculae, and focal papillary formations. Tumor cells were columnar with enlarged, overlapping vesicular nuclei and pale cytoplasm, expressing GATA3, S100, SOX10, and DOG1, while lacking mammaglobin expression. Focal p63/p40 positivity suggested a possible preexisting in situ component. BRAF fusions are exceedingly rare in salivary gland tumors and may occur across different histologic types. Given their potential sensitivity to MEK or next-generation RAF inhibitors, comprehensive molecular testing is essential for identifying patients who may benefit from targeted therapies. - Source: PubMed

Approximately 25% of BHD syndrome patients are diagnosed with renal tumors, which can be multifocal and/or bilateral. These tumors have been reported to span a broad histologic spectrum; however, the majority exhibit a distinctive histology characterized by intermingled cytologic features similar to that seen in oncocytoma and chromophobe renal cell carcinoma. Accordingly, such tumors were previously termed 'hybrid oncocytic chromophobe tumor' (HOCT). To date, most studies have characterized tumors arising in BHD syndrome patients without molecular confirmation of FLCN biallelic inactivation; accordingly, the clinicopathologic characterization of molecularly confirmed FLCN biallelic inactivated tumors remains limited. This study evaluates a multi-institutional cohort of 18 renal tumors from different individuals, including integrated histologic, immunohistochemical, and targeted next-generation sequencing analyses. While all patients exhibited clinical characteristics raising suspicion for BHD syndrome, germline status was not available in 5 patients. Nevertheless, molecular analysis demonstrated findings supportive of FLCN biallelic inactivation in all patients, and there were no other candidate driver alterations or recurrent molecular findings. Histologically, most tumors showed 'conventional' histology consisting of solid or nested growth with a characteristic mosaic population of eosinophilic and clear cells and low-grade nuclear features, including frequent perinuclear halos and binucleation. Two cases showed 'non-conventional' histology including tubulocystic and tubulopapillary architecture. Immunohistochemistry revealed consistent GPNMB expression and a distinctive mosaic staining pattern for KRT7, L1CAM, and GATA3, aiding distinction from other eosinophilic renal neoplasms. Follow-up was available for 17 patients (median 37 months, range 1-110 months). Both patients with non-conventional morphology demonstrated advanced stage at presentation, including one with metastatic disease. Collectively, these findings define one of the largest molecularly-confirmed cohorts of FLCN biallelic inactivated tumors to date and support recognition of FLCN-driven tumors as a distinct, molecularly defined entity. - Source: PubMed

We characterized 16 cases of PTCL, NOS diagnosed in patients ≤21 years old. Seven (44%) cases demonstrated SMARCB1/INI1 loss by immunohistochemistry and SMARCB1/INI1 alterations by next-generation sequencing, including biallelic SMARCB1/INI1 deletion (n=4), stop codon variant with 1-copy deletion (n=1) or copy-neutral loss-of-heterozygosity (CN-LOH; n=1), and frameshift variant (n=1). One case demonstrated biallelic SMARCE1 alterations (a nonsense variant and CN-LOH), which, to our knowledge, has not been previously described in a hematopoietic neoplasm. The SWI/SNF-intact group harbored pathogenic TET2, PTEN, EZH2, or TP53 variants. CDKN2A deletions were present in 3/7 SWI/SNF-deficient and 0/4 SWI/SNF-intact cases. 22q11.2 alterations were present on karyotype of 2/3 SMARCB1/INI1-deficient cases. SWI/SNF-deficiency was associated with intermediate-to-large cell cytomorphology, frequent mitotic (88%; p=0.041) and apoptotic (88%) activity, Reed-Sternberg-like cells (63%), necrosis (50%), and fibrosis (50%). All cases expressed CD45 and CD43 at initial diagnosis. SWI/SNF-deficient cases predominantly demonstrated a CD4+/CD8-, TCRab, and PTCL-GATA3 phenotype, whereas SWI/SNF-intact cases predominantly demonstrated a CD8+/CD4-, TCRgd, and PTCL-TBX21 phenotype. A PTCL-TBX21 phenotype was more common in SWI/SNF-intact than SWI/SNF-deficient cases (p=0.041). Cytotoxic markers were expressed in 71% of SWI/SNF-deficient and 88% of SWI/SNF-intact cases. Decreased or absent CD3 expression characterized 88% of SWI/SNF-deficient and 13% of SWI/SNF-intact cases (p=0.01). 63% of SWI/SNF-deficient cases demonstrated decreased/absent expression of ≥3 pan-T-cell antigens, compared to 13% of SWI/SNF-intact cases. Treatment was heterogeneous. Primary treatment failure or relapse occurred in 4/8 SWI/SNF-deficient and 4/7 SWI/SNF-intact cases. The median OS and EFS were 48.7 and 47.5 months for the SWI/SNF-deficient, and 16.4 and 8.9 months for the SWI/SNF-intact groups, respectively (p=NS). Death due to disease or therapy-related complications occurred in 4/8 (50%) cases in the SWI/SNF-deficient group and 6/7 (86%) of cases in the SWI/SNF-intact group. Our findings expand the knowledge of the clinicopathologic and molecular features of pediatric PTCL and highlight SWI/SNF-deficient T-cell lymphoma as a biologically distinct type of PTCL that is associated with characteristic clinicopathologic features. - Source: PubMed

Renal lipotoxicity and chronic inflammation form a self-perpetuating cycle driving DKD, yet multitarget interventions remain underexplored. We hypothesized that simultaneous inhibition of ANGPTL3 and IL-33, two key regulators of lipid metabolism and the inflammatory-fibrotic axis, would ameliorate DKD, and that integrating both antagonistic activities into a single bifunctional molecule offers translational advantages. We engineered a bifunctional fusion protein, FD03-sST2, comprising an anti-ANGPTL3 nanobody fused to the IL-33 decoy receptor sST2. In high-fat diet-fed db/db mice, FD03-sST2 significantly improved renal function (ACR, BUN, urine volume), reduced serum/hepatic lipids, and attenuated renal lipid accumulation. Mechanistically, it suppressed renal inflammation via NF-κB/NLRP3 inhibition and ameliorated fibrosis by suppressing the IL-33/ST2/ILC2 axis (reducing renal IL-33/GATA3 signals and inhibiting IL-33-induced profibrotic factors from ILC2s). Transcriptomic and metabolomic analyses confirmed attenuation of DKD-associated dysregulation. This study identifies a DKD cascade wherein lipotoxicity triggers IL-33 release, amplifying injury through inflammation and fibrosis. By targeting ANGPTL3 and IL-33 simultaneously, FD03-sST2 interrupts this vicious cycle at two nodes-improving lipid metabolism while suppressing downstream inflammatory and fibrotic signaling-providing an integrated alternative to separate biologics. - Source: PubMed

Although generally indolent, SBC carries a risk of local recurrence even decades after treatment. Its defining molecular hallmark is the ETV6-NTRK3 fusion. - Source: PubMed
