Inflammatory leiomyosarcoma is a soft-tissue tumor resembling conventional leiomyosarcoma, but with prominent intrinsic inflammatory component. Previous studies have suggested that differs genetically from in-depth analyses are lacking. Here we provide comprehensive picture of the genome and transcriptome by combining cytogenetic, single-nucleotide polymorphism array, mRNA-sequencing, whole-exome sequencing data. The results show has specific genetic profile characterized near-haploidization...

Abstract Well-differentiated liposarcoma (WDLS) displays amplification of genes on chromosome 12 (Chr12) in supernumerary ring or giant marker chromosomes. These structures have been suggested to develop through chromothripsis, followed by circularization and breakage-fusion-bridge (BFB) cycles. To test this hypothesis, we compared WDLSs with Chr12 rod-shaped chromosomes rings. Both types amplicons share the same spectrum structural variants (SVs), show higher SV frequencies than...

The aim of the study was to evaluate diagnostic utility fine needle aspiration (FNA) cytology and core biopsies (CNBs) in a series primary soft tissue bone lesions test possible system for reporting results FNA lesion.This retrospective encompassed 828 lesions, analysed with FNA, CNB and/or surgical specimen order perform sensitivity/specificity as well accuracy analyses. then used cytopathology six categories risk malignancy each category calculated.With malignant diagnosis defined positive...

The dermatofibrosarcoma protuberans family of tumors (DPFT) comprises cutaneous soft tissue neoplasms associated with aberrant PDGFBR signaling, typically through a COL1A1-PDGFB fusion. aim the present study was to obtain better understanding chromosomal origin this fusion and assess spectrum secondary mutations at chromosome nucleotide levels. We thus investigated 42 tumor samples from 35 patients using banding, fluorescence in situ hybridization, single polymorphism arrays, and/or...

Abstract Myxoid liposarcoma (MLS) is molecularly characterized by fusions involving the DDIT3 gene in chromosome band 12q13; fusion partner FUS 16p11 90–95% of cases and EWSR1 22q12 remaining 5–10%. Hence, molecular studies, often fluorescence situ hybridization (FISH) for rearrangement, are useful establishing a correct diagnosis. Although all MLS tumors should have fusions, it important to be aware reasons potential false‐negative results. We here present case that was negative FISH ,...

Morphologic and immunohistochemical analysis of preoperative core needle biopsies (CNB) is important in the management patients with soft tissue bone tumors (STBTs). Most SBTB subtypes have more or less extensive DNA copy number aberrations (CNA), potentially providing useful diagnostic information. To evaluate technical feasibility single nucleotide polymorphism (SNP) array usefulness profiles, we studied CNBs from 171 suspected STBTs. SNP could be performed on 168 (98%) samples. The CNA...

Near-haploidization, that is, loss of one copy most chromosomes, is a relatively rare phenomenon in tumors, but enriched among certain soft tissue sarcomas, including undifferentiated pleomorphic sarcoma (UPS). Presumably, near-haploidization can arise through many mechanisms. This study aimed to identify gene rearrangements could cause near-haploidization. We here present two UPS which was an early event, identified single nucleotide polymorphism (SNP) array analysis. One the cases studied...

ABSTRACT Objective Fine‐needle aspiration cytology (FNAC) from bone lesions has been proven to be a useful diagnostic tool but lacks standardisation. The aim of the study was evaluate utility FNAC as basis propose and test reporting system for cytopathology. Methods This retrospective is based on patients with lesions, that were approached by at Skåne University Hospital, Sweden between 2015 2023. performance measured sensitivity, specificity accuracy analyses. All diagnoses then distributed...

A 15-month-old boy with a 2-month history of watery diarrhoea presented cachexia, hypokalaemia, hypochloraemia and metabolic acidosis. During 2-week investigation period infection, celiac disease cystic fibrosis were excluded trial therapy antibiotics, probiotics dietary measures proved unsuccessful. This led to the suspected diagnosis vasoactive intestinal polypeptide (VIP)-secreting tumour diarrhoea, achlorhydria (WDHA)-syndrome. MRI showed an infrarenal mass infiltrating neuroforamen,...
