In recent years, SoMe platforms have become increasingly adopted by cytopathologists, facilitating continued education, professional networking, enhancing patient engagement, and entertainment. This adoption has influenced the professional growth of cytopathologists, and at its best, has led to the establishment of a robust professional online presence and ultimately contributed to leadership positions, fellowship opportunities, and academic promotions. Moreover, the integration of SoMe into the academic field has shown a profound impact on the visibility of academic journals and has provided a platform for lower-impact factor journals to expand their reach, ultimately increasing article citation rates and positively contributing to journal impact factor growth. SoMe platforms created a modern avenue for conference networking that has revolutionized knowledge dissemination and enhanced real-time engagement. The advantages of SoMe have extended to a global scale, positively enhancing professional expertise sharing, facilitating effective communication and teleconsultation worldwide, and reaching developing countries. Drawing insights from the recent medical literature and the practical insight from the experts' personal experience, this article provides a comprehensive review of how SoMe and cytopathology intersect to create new opportunities, facilitating informed discussions, global collaboration, and advancements in the field of cytopathology. This article also delves into the challenges surrounding SoMe platform navigation and addresses ethical and regulatory concerns, providing guidelines on what to post and what not to post on SoMe platforms.</p>","PeriodicalId":11349,"journal":{"name":"Diagnostic Cytopathology","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140854096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Oral and oropharyngeal squamous cell carcinoma (O- and OP-SCC) can potentially metastasize to the parotid gland or intraparotid lymph nodes. Fine-needle aspiration cytology (FNAC) serves as the initial diagnostic approach for this purpose. HPV status in FNAC specimens is relevant and can guide the diagnostic workup, indicating a potential oropharyngeal origin of the primary tumor. A small series of occult SCC metastases is presented below, in which HPV-DNA testing of FNAC specimens helped identify primary neoplasms located in the oropharynx. US-guided FNAC of parotid nodules was conducted by an experienced interventional cytopathologist in three cases. Each patient underwent assessment of direct smears, cell blocks, and liquid-based samples for HPV testing. The morphological and immunocytochemical features of SCC were documented, and real-time PCR was employed for the detection and genotyping of HPV.
