Hepatocellular neoplasms are the most common primary liver malignancies and hepatoblastoma (HB) is the most frequently diagnosed. The incidence of HB, which is increasing, is approximately of 2 cases per million in the United States, followed by hepatocellular carcinoma (HCC). Pediatric primary liver tumors of mesenchymal origin are less common, except for benign vascular tumors (hemangiomas). Malignant mesenchymal neoplasms represent approximately 10-15% of all, the most common being embryonal sarcoma and malignant rhabdoid tumor. Malignant vascular tumors are rare, but epithelioid hemangioendothelioma (EHE) and angiosarcoma can be seen in children. The development and adoption of consensus diagnostic, therapeutic and risk-stratifying approaches for pediatric patients with malignant liver tumors has been historically challenged by their rarity and by their diverse clinical and histological appearance.

In addition, a distinctive spindle cell stroma, that is immunohistochemically-positive for S100, is often observed in BCAs. Based on the ultrastructural findings, the S100-positive stroma was presumed to originate from neoplastic myoepithelial cells. However, immunohistochemical studies do not provide strong evidence supporting a myoepithelial origin, and the true nature of this stroma remains elusive. The aim of this study was to determine whether the S100-positive stroma was neoplastic through a molecular analysis. We selected 2 cases involving BCAs with at least one S100-positive stromal area within the tumor, measuring ≥ 0.2 × 0.2 mm. CTNNB1 I35T mutations were detected in both tumors by Sanger sequencing. Two areas of S100-positive stroma from these two tumors were successfully dissected by manual microdissection using a stereomicroscope without contamination from the surrounding neoplastic bilayered epithelial cells. Because of the small number of dissected stromal cells, the mutation status of these two areas was analyzed using digital PCR, and CTNNB1 I35T mutations were detected in both. In conclusion, this study demonstrated that the S100-positive stroma of BCAs exhibits a neoplastic nature from a molecular perspective. While future studies are needed to confirm whether the S100-positive stroma originates from myoepithelial cells, BCAs morphologically display tricellular differentiation, with neoplastic spindle-shaped stromal cells along with a bilayered neoplastic epithelium.</p>","PeriodicalId":23514,"journal":{"name":"Virchows Archiv","volume":" ","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142898566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
