Article Abstract
EGFR-kinase-domain duplication (KDD) has been reported in Infantile fibrosarcoma-like myofibroblastic tumors and cellular mesoblastic nephroma. We report a pulmonary neoplasm with EGFR-(KDD) and infantile fibrosarcoma-like histologic features in a female infant with an unusual clinical and histologic evolution, characterized by persistent disease with morphologic features of Congenital Peribronchial Myofibroblastic Tumor (CPMT) after chemotherapy and targeted therapy. The CPMT morphology with EGFR-KDD in the post-therapy specimen might be an evolution induced by the treatment, which suggests the hypothesis that CPMT is part of the morphologic spectrum of infantile fibrosarcoma/cellular mesoblastic nephroma.

Reviewing the Developing Significance of the Serine Protease PRSS23.

The serine protease 23 (PRSS23) is a highly conserved member of trypsin-like serine proteases, which are associated with numerous essential processes, including digestion, blood coagulation, fibrinolysis, development, fertilization, apoptosis, and immunity. Original reports on PRSS23 unfolded not earlier than 2006 when a molecular biology study characterized and described PRSS23 as an ovarian protease. Then, in 2012, another important study was published linking PRSS23 with proliferation of breast cancer cells by an estrogen receptor 1 (ESR1)-dependent transcriptional activation of the serine protease.

Lymph node metastasis (LNM) is a critical prognostic factor for patients with oral squamous cell carcinoma (OSCC). Previous research has implicated the partial epithelial-to-mesenchymal transition of tumor cells and myofibroblastic cancer-associated fibroblasts (myCAFs) in the LNM process. However, the underlying molecular mechanisms remain poorly understood.

Anaplastic lymphoma kinase ()-rearranged myxoid spindle cell tumors represent a recently recognized subgroup of kinase fusion-positive mesenchymal neoplasms. These tumors often arise in the superficial soft tissues but may occasionally be found in deeper tissues, or, rarely, within visceral organs. The term (SAMS) comprises a distinct subset of cutaneous soft tissue tumors with superficial location and spindle cell morphology, exhibiting bland cytomorphology and favorable clinical outcomes.

To retrospectively analyze the cases of inflammatory myofibroblastic tumor (IMT) involving the sinonasal skull base, and to investigate their clinical characteristics, diagnostic approaches, and treatment outcomes, in order to improve understanding of this rare entity. Clinical data from five patients with pathologically confirmed sinonasal skull base IMT who underwent surgical treatment at Xiangya Hospital of Central South University between April 2010 and June 2023 were reviewed. Information on clinical presentation, laboratory findings, imaging features, histopathological and immunohistochemical results, treatment strategies, and follow-up outcomes was collected.
