Osteofibrous dysplasia-like and classic forms are well known; however, sarcomatous transformation (dedifferentiation) is very rarely observed. We present the case of a 48-year-old woman who presented with a 5-cm proximal femoral lytic lesion at risk of pathologic fracture. Frozen-section evaluation demonstrated an intimate admixture of atypical squamous nests and spindle cells, consistent with metastatic sarcomatoid carcinoma, so prophylactic intramedullary nailing was completed. Postoperative clinical and radiologic evaluation failed to identify a primary carcinoma, and short-term follow-up demonstrated rapid tumor spread throughout the femur and thigh. The patient underwent hip disarticulation, and microscopic examination demonstrated areas of classic adamantinoma associated with both high-grade epithelial and sarcomatoid components. Diffuse metastatic spread was evident within seven months. Along with a description of this case, we review the clinical, radiographic, histologic, and immunophenotypic characteristics of the eight adamantinomas with high-grade sarcomatous transformation that have been previously reported in detail in the English literature, and discuss important considerations for differential diagnosis.","PeriodicalId":43475,"journal":{"name":"AJSP-Reviews and Reports","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80761713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We describe an unusual case of LCH with solitary hepatic involvement. Histopathologic materials from both native and allograft specimens, including all biopsies, explant hepatectomies, and correlating clinical data accumulated over a 10-year interval, were reviewed. A 46-year-old woman presented with jaundice and pruritus. An initial workup including liver biopsy led to the diagnosis of antimitochondrial antibody–negative primary biliary cholangitis with advanced fibrosis. Within a year, the patient progressed to decompensated cirrhosis requiring transplantation. Her posttransplant course was complicated by frequent bouts of markedly elevated alkaline phosphatase and γ-glutamyl transferase with mild liver transaminases elevation. These abnormalities and the liver biopsy findings of bile duct injury and portal inflammation were thought to be acute cellular rejection. Her liver enzymes showed some improvement but never completely normalized on high-dose steroid and became elevated once the therapy stopped. Three years after transplantation, the diagnosis of LCH was established based on the histopathology and immunohistochemistry in the allograft biopsy. Four more years later, the patient lost the liver allograft and required a second transplantation. The explanted allograft revealed patchy distribution of the disease, confirming difficulty of LCH diagnosis on a liver biopsy without systemic involvement. For clinicians and pathologists, it is critical to exclude hepatic involvement by LCH before rending a diagnosis of antimitochondrial antibody–negative primary biliary cholangitis or small duct primary sclerosing cholangitis.","PeriodicalId":43475,"journal":{"name":"AJSP-Reviews and Reports","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76288994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, recent studies have identified high-risk HPV in other, clinicopathologically distinct tumors in this region. We report a series of cases involving two unique HPV-mediated neoplasms. Human papillomavirus–related multiphenotypic sinonasal carcinoma is a locally aggressive tumor arising exclusively in the sinonasal tract with pathologic features reminiscent of high-grade adenoid cystic carcinoma. Ciliated adenosquamous carcinoma often presents as a unilateral neck mass and consists of admixed nonkeratinizing squamous cell carcinoma and glandular elements, which may be deceptively bland. Cilia are often present, which are traditionally associated with benignity and may lead to misdiagnosis as a benign branchial cleft cyst. In most cases, an oropharyngeal primary tumor is later identified. Despite aggressive features, both entities have a relatively favorable prognosis. These unusual tumors present unique diagnostic challenges that require particular attention to prevent misdiagnosis and mistreatment.","PeriodicalId":43475,"journal":{"name":"AJSP-Reviews and Reports","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78102811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
