Rhabdomyosarcomas (RMSs) are soft tissue sarcomas that are one of the most common neoplasms in children and adolescents. RMSs are presumed to be associated with the skeletal muscle lineage, although those tumors can be present in organs histologically lacking skeletal muscle, like prostate, urinary bladder or gallbladder. RMS is divided into two major subtypes: embryonal (ERMS) and alveolar (ARMS). Alveolar rhabdomyosarcoma (ARMS) is a pediatric sarcoma that typically occurs in older children predominantly arising in the trunk and extremities, and exhibits a worse prognosis than other types of RMSs. ARMS is associated with 2;13 or 1;13 chromosomal translocations, which generate PAX3-FOXO1A and PAX7-FOXO1A fusion products, respectively. These translocations result in altered expression, function, and subcellular localization of the fusion products relative to the wild-type proteins, and ultimately contribute to oncogenic behavior by modifying growth, differentiation, and apoptosis pathways.

Title
Extending the phenotypes associated with DICER1 mutations.
Diffuse large B-cell lymphoma, not otherwise specified (DLBCL, NOS) is the most common type of DLBCL. DLBCL accounts for 30-40% of all non-Hodgkin lymphomas (NHL), making it the most prevalent form of NHL. DLBCL can occur as primary disease or through histologic transformation from other low-grade B-cell lymphoma, and is a clinically and genetically heterogeneous disease. The cell-of-origin (COO) determination based on gene expression profiling (GEP) subdivides most DLBCL, NOS patients into two main categories, namely germinal center B-cell-like (GCB) and activated B-cell-like (ABC) DLBCL. GCB subtype is characterized by frequent mutations in involved histone methylation or acetylation (EZH2, EP300), B-cell homing (GNA13, GNAI2), PI3K pathway signalling (PTEN), and apoptotic pathway (BCL2). In contrast, ABC subtype is driven by frequent mutations in the B cell receptor and NFKB pathways (CARD11, CD79a/CD79b, TNFAIP3 and MYD88).
