Cytodiagnostic features of angiofibroma of soft tissue: A review of 16 cases to identify characteristic findings and their diagnostic significance

Cancer Cytopathology, Volume 134, Issue 9, September 2026.
Abstract Background Angiofibroma of soft tissue (AFST) is a rare benign fibroblastic/myofibroblastic neoplasm. Despite several published studies describing the clinicopathological features of AFSTs, its cytological characteristics remain poorly documented. This study aimed to identify distinctive cytological features that may support accurate diagnosis.

A subset of high‐grade sarcomas with myogenic differentiation are associated with recurrent FGFR fusions

The Journal of Pathology: Clinical Research, Volume 12, Issue 4, July 2026.
Abstract Recurrent fusions involving FGFR1‐4 genes have been previously described in rare subsets of mostly benign chondroid and mesenchymal neoplasms involving bone and soft tissue. However, a more comprehensive analysis of sarcomas associated with FGFR fusions, including their incidence and histotypes, has not been performed.
