Pathoage is a research resource for exploring tissue-specific clinical features associated with age and mortality. It brings together information extracted from more than 33 million text descriptions of histological samples, helping users examine how clinical features relate to different tissue types. The site organizes its content by tissue using SNOMED CT identifiers and names, with searchable listings and sample counts for each entry.

Examples include adrenal gland, anus, aorta, appendix, bladder, blood, and blood vessels. Users can browse the tissue catalogue across multiple pages and download its data as a CSV file for further analysis. Pathoage also provides background about the resource and directs visitors to a research paper for further details on the work behind it.

Designed as a comprehensive reference for investigating age- and mortality-associated features across tissues, Pathoage makes a large body of histological descriptions easier to explore in a structured way. Its focus is on tissue-specific data and research access rather than on clinical diagnosis or patient services
