This study provides a comprehensive bibliometric analysis of prurigo nodularis (PN) literature, identifying influential studies, key contributors, and emerging trends to understand the evolution of research and guide future investigations. A total of 499 contributions published between 1951 and October 2024, containing the term "prurigo nodularis" in their abstracts, were analyzed. Keyword analysis was conducted to determine the main themes across these publications. Additionally, the top 100 most cited articles on PN from 1979 to 2023 were examined, involving 51 journals. Metrics such as mean total citations per contribution (MeanTCperArt) and mean total citations per year (MeanTCperYear) were calculated for these top 100 articles. The analysis of the top 100 most cited articles revealed contributions from 453 authors. The number of publications, citations, h-index, g-index, m-index, hg composite, and Q2 index were calculated for each author. We have illustrated the dynamics of top authors, universities, and countries, as well as their respective collaboration networks. The thematic evolution of PN research was assessed using coword analysis, followed by a systematic discussion of the findings. This bibliometric analysis provides a comprehensive overview of the key contributors and research trends in PN literature, offering valuable insights for guiding future investigations.
