Gaining a comprehensive understanding of both common and rare odontogenic tumors is crucial for their effective study and clinical management. One particularly puzzling tumor is the \"plexiform ameloblastoma,\" a variant of the solid multicystic ameloblastoma. This term describes a distinct pattern of epithelial proliferation within the cystic cavity. Numerous studies have emphasized the variability of the stromal component, further highlighting the enigmatic nature of ameloblastoma. The presence of unique and rare features, such as primitive, mature desmoplastic, hemangiomatous, or ghost cells within the stroma of plexiform ameloblastoma, underscores the differentiation potential of the neoplastic odontogenic epithelium and offers significant insights into the tissue reactions associated with this condition.

It was newly incorporated into the 2022 WHO classification of odontogenic lesions, standing as the sole novel entity in this update. AA is also regarded as a hybrid tumor because of the combination of histological characteristics observed in both adenomatoid odontogenic tumors and ameloblastoma. Clinically, it presents similarly to other ameloblastoma variants, with patients typically exhibiting a painless, slow-growing jaw swelling. However, this subtype is noted for its more aggressive behavior, including a higher recurrence rate and greater local invasiveness. Histopathologically, AA is distinguished by an intricate arrangement of epithelial islands, cords, and strands, generating a cribriform architectural pattern, with peripheral palisading and central stellate reticulum-like formations. Immunohistochemical profiling reveals the expression of epithelial differentiation markers, including cytokeratins, and proliferative markers such as Ki-67, further corroborating its aggressive phenotype. While its precise etiopathogenesis remains obscure, the unique histological characteristics imply a potentially distinct underlying molecular pathway. Due to its aggressive nature, AA necessitates meticulous clinical and histopathological evaluation and tailored therapeutic strategies to mitigate recurrence risks and optimize patient prognoses. Furthermore, this review integrates histological and molecular insights from recent studies conducted after its inclusion in the updated WHO classification.</div></div>","PeriodicalId":49548,"journal":{"name":"Seminars in Diagnostic Pathology","volume":"42 1","pages":"Pages 13-17"},"PeriodicalIF":2.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142479024","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}

Among its subtypes, the desmoplastic and plexiform variants are relatively rare, with the hybrid form, encompassing both architectural patterns, representing an even more exceptional entity. This article delineates the clinical, radiological, and histopathological profile of a 45-year-old male presenting with pain persisting over the past month in the right posterior maxillary region. Radiographic imaging displayed a mixed radiolucent-radiopaque lesion with poorly demarcated margins, indicative of an aggressive pathology. Histopathological examination revealed a hybrid ameloblastoma, juxtaposing desmoplastic zones with densely fibrotic stroma and classic plexiform sections with epithelial strands in a reticular configuration. This unique hybrid variant underscores the complexity of ameloblastomas and necessitates comprehensive histopathological assessment, as radiological interpretations may prove insufficient for accurate diagnosis.

Salivary gland-like carcinomas included in the World Health Organization classification of breast tumors are adenoid cystic carcinoma, secretory carcinoma, mucoepidermoid carcinoma, acinic cell carcinoma, and the exceedingly rare polymorphous adenocarcinoma. These carcinomas are usually triple negative for estrogen receptor and progesterone receptor expression and HER2 overexpression, yet generally have favorable prognosis, in contrast to high-grade triple negative carcinomas of no special type. On the other hand, a small subset, such as solid-basaloid adenoid cystic carcinoma, rare high-grade carcinomas, and those associated with transformation to other types of high-grade invasive carcinoma can behave more aggressively. Other salivary gland-like tumors of the breast, such as pleomorphic adenoma and adenomyoepithelioma, are usually benign but can rarely undergo malignant transformation. Although clinical experience with salivary gland-like breast tumors is overall limited, their recognition and accurate classification has important implications for prognosis and clinical management, especially to avoid overtreatment of salivary gland-like carcinomas. The identification of characteristic genetic alterations and/or immunohistochemical surrogates in many of these tumors has practical applications to establishing an accurate diagnosis and directing clinical management. This review highlights the histopathologic and genetic characteristics of salivary gland-like breast tumors and the implications of the diagnosis for current clinical management.</div></div>","PeriodicalId":49548,"journal":{"name":"Seminars in Diagnostic Pathology","volume":"41 6","pages":"Pages 272-284"},"PeriodicalIF":2.9,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142401759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
