School of Pathology



Pathology is the study of disease. It is the bridge between science and medicine. It underpins every aspect of patient care, from diagnostic testing and treatment advice to using cutting-edge genetic technologies and preventing disease.  The disciplines that come under the Pathology umbrella are Haematology, Infectious diseases with Medical Microbiology or Virology, Histopathology and Immunology.  Each discipline addresses different aspects of laboratory medicine.  Haematology and Immunology include a significant component of clinical management with potential contact with patients.  The role of the histopathologist involves diagnosis from assessment of tissue and cellular samples and is essential for the management of suspected cancer cases and other clinical conditions requiring a tissue diagnosis.  Histopathology is also the route of entry into forensic (autopsy) pathology, paediatric/perinatal pathology and Diagnostic Neuropathology.

Head of School

The Head of School of Pathology is Dr Catherine Horsfield, a Histopathologist at Guy’s & St Thomas’ specialising in Medical and Transplant Renal Pathology and Uropathology.

Specialty Training Board Information

The London Specialty School of Pathology holds Specialty Training Board meetings twice per year. The purpose of this group is to bring together specialty leads from postgraduate medical training programmes across the three London local education and training board areas to consider issues of mutual interest in relation to Pathology, and to foster and share good training practice on a pan London basis.
