Doctors in Sheffield will be the first to use a high-tech skin cancer diagnostic kit.
The TeleDerm service, which uses a specialist microscope, will be trialled in three GP surgeries in the city.
The dermascope produces a high quality image of the underlying structures of the skin using light and magnification.
The service should help cut the number of misdiagnosed cases of malignant melanomas and the number of people referred unnecessarily with benign pigmented lesions or moles.
It is being spearheaded by the Central Sheffield GP Consortium - a group of GPs in 27 practices in the city.
Michelle Wilde, practice manager at Manor Top Surgery, part of the Consortium, said: "This service will increase the quality of diagnosis of pigmented lesions or moles, and will cut down on the significant number of people unnecessarily referred to hospital with benign, non-cancerous moles and marks.
Patients going to consortium GPs with concerns about a mole or abnormal skin lesion will be referred to specialist TeleDerm clinics being held at Dovercourt, Darnall and Gleadless surgeries.
Digital images produced by the dermascope will be analysed by skin care specialists who will produce a dermascopic investigation report for the referring GP within three days.
