Our dermatology department is known as St John's Institute of Dermatology.


John MiltonJohn Milton founded St John's Hospital for Diseases of the Skin in 1863. He was a surgeon who suffered from hand eczema so severe it ended his career. His personal experience with skin disease triggered his interest in dermatology.

The hospital was based in several different locations in Soho in the early 20th century. After World War II it occupied outpatient premises in Lisle Street, Leicester Square.

St John's Hospital for Diseases of the Skin moved to St Thomas' Hospital in the mid-1980s. Soon after, St John's was formally renamed St John's Institute of Dermatology.

St John's outpatients reception

St John’s remained at St Thomas’ until very recently when the newly refurbished Bermondsey Centre opened at Guy’s Hospital in November 2015. It now sees the institute’s 36 consultants and 25 clinical nurse specialists treating patients with the most challenging skin conditions who come from across the country and the globe.

Self check-in and an electronic patient calling system is now used at the dermatology reception. 

These were introduced as part of our programme of improvements within dermatology, lupus and rheumatology services at Guy’s Hospital. Read more in the April edition of the our newsletter (PDF 399Kb).
