Atypical mycobacterioses are unusual infections of the skin and other organs caused by non-tuberculous mycobacteria. Fish tank granuloma and swimming pool granuloma are two forms of atypical mycobacterioses caused by Mycobacterium marinum. So far, only a few cases of these infections have been reported in organ transplant patients, and these usually are more severe when compared with atypical mycobacterioses in immunocompetent hosts. We report a kidney transplant patient with a rather mild form of atypical mycobacteriosis (fish tank granuloma) who responded well to treatment with doxycycline and will provide a review of all similar cases reported in the literature.

Aims/Background: Congenital dermatological diseases (CDD), a complex group of inherited or developmental skin disorders, pose challenges in their management owing to their genetic nature, clinical variability, and socioeconomic impact. Despite the growing body of research, gaps remain in our understanding of research trends, collaborative networks, and translational advancements in this field. This bibliometric study evaluates CDD research over the last three decades (1995–2024) to identify its key developments and Emerging Themes. Methods: A comprehensive bibliometric analysis was conducted using the Scopus database (October 2024), owing to its extensive peer-reviewed coverage and reliable citation tracking. A multistep search strategy was used to refine the dataset and ensure its relevance. Bibliometrix and VOSviewer were used for quantitative and network-based analyses, highlighting publication trends, author impacts, and thematic structures. Results: CDD research expanded significantly between 1995 and 2024, with 17,984 publications and the majority being published in the last decade. The average age of the documents was 11.6 years, reflecting sustained engagement. Author metrics (h-index, g-index, and m-index) identified leading contributors, while co-authorship and collaboration networks revealed global research dynamics. The co-word analysis outlined the evolving thematic framework, including trends in diagnostic tools and therapeutic innovations. Conclusion: This study provided a structured overview of CDD research and identified critical gaps in its diagnosis, treatment strategies, and interdisciplinary collaboration. Understanding these trends can inform clinical decision-making, enhance early diagnosis, and support the development of targeted therapies, ultimately improving patient outcomes.
