Careful pathologic analysis plays a critical role in the diagnosis and clinical management of UTUC. In combination with clinical and radiologic evaluation, pathologic features can be used to stratify patients into low-risk and high-risk groups. This risk stratification can help clinicians select the optimal treatment for patients with UTUC, such as kidney-sparing (conservative) treatment, radical nephroureterectomy or ureterectomy, and perioperative systemic therapy. However, due to the technical difficulty of obtaining sufficient tissue from the upper urinary tract, it is often challenging for pathologists to accurately grade the tumor and assess tumor invasion in small biopsy specimens. Although the majority of UTUCs are pure urothelial carcinoma, a considerable subset of UTUCs show histologic subtypes or divergent differentiation. Recent studies have identified genetically distinct molecular subtypes of UTUC by examining DNA, RNA, and protein expression profiles. The prognosis of pT3 UTUC, particularly renal pelvic UC, remains controversial, and several studies have proposed subclassification of pT3 UTUC. Lynch syndrome is a significant risk factor for UTUC, and screening tests may be considered in young patients and those with familial histories of the disease.

Initial studies of TSC-associated RCC categorized tumors into 3 broad heterogeneous morphologic groups: RCC with smooth muscle stroma, chromophobe-like, and eosinophilic-macrocytic. Recently, a similar morphologic spectrum has been increasingly recognized in novel and emerging entities characterized by somatic mutations in the TSC1/2 and MTOR in patients who do not suffer from the TSC. Correct recognition of RCC with TSC / MTOR mutations is critical for accurate prognostication because such tumors with aggressive behavior have the potential to be tailored to mTOR inhibitors. Whether TSC/MTOR mutated renal epithelial neoplasms represent a distinct molecular class has been confounded by the fact that TSC1/2 , and the gene encoding the downstream protein MTOR, are mutated secondarily in ∼5% of the more common subtypes of RCC, including the commonest subtype of clear cell RCC. This review summarizes the expanding morphologic spectrum of renal tumors with TSC/mTOR pathway alterations, specifically for sporadically occurring tumors where these genomic alterations likely are primary pathologic events.

However, as a new era of Twitter leadership began to unfold in October 2022, a young platform called \"Mastodon\" began to gain notice within this community as the hashtag #PathMastodon became prevalent. Founded in 2016 by Eugen Rochko, Mastodon is a decentralized, open-sourced, ads-free platform intended to promote public knowledge in a safe and public manner. When compared with Twitter, however, Mastodon is globally much smaller, and its medical professional server called \"Med-Mastodon\" is more cumbersome with certain features (eg, tracking analytics and username changes).

Recently, an influx of Large Language Models has emerged in the medical and academic discussion, given their potential widespread application to improve patient care and provider workflow. One application that has gained notable recognition in the literature is ChatGPT, which is a natural language processing \"chatbot\" technology developed by the artificial intelligence development software company OpenAI. It learns from large amounts of text data to generate automated responses to inquiries in seconds. In health care and academia, chatbot systems like ChatGPT have gained much recognition recently, given their potential to become functional, reliable virtual assistants. However, much research is required to determine the accuracy, validity, and ethical concerns of the integration of ChatGPT and other chatbots into everyday practice. One such field where little information and research on the matter currently exists is pathology. Herein, we present a literature review of pertinent articles regarding the current status and understanding of ChatGPT and its potential application in routine diagnostic pathology. In this review, we address the promises, possible pitfalls, and future potential of this application. We provide examples of actual conversations conducted with the chatbot technology that mimic hypothetical but practical diagnostic pathology scenarios that may be encountered in routine clinical practice. On the basis of this experience, we observe that ChatGPT and other chatbots already have a remarkable ability to distill and summarize, within seconds, vast amounts of publicly available data and information to assist in laying a foundation of knowledge on a specific topic. We emphasize that, at this time, any use of such knowledge at the patient care level in clinical medicine must be carefully vetted through established sources of medical information and expertise. We suggest and anticipate that with the ever-expanding knowledge base required to reliably practice personalized, precision anatomic pathology, improved technologies like future versions of ChatGPT (and other chatbots) enabled by expanded access to reliable, diverse data, might serve as a key ally to the diagnostician.
