Frequently asked questions
Phototherapy uses controlled exposure to ultraviolet (UV) light to treat certain skin conditions. It can be used for conditions including vitiligo, psoriasis and some forms of eczema and sun allergy. Dr Ferguson offers phototherapy at Welbeck and is clinical lead for phototherapy at the St John's Institute of Dermatology. He can assess whether it's an appropriate treatment for your particular skin condition during your consultation.
Yes. Vitiligo is one of Dr Ferguson’s specialist areas, and he is the clinical lead for vitiligo at the St John's Institute of Dermatology. During your consultation Dr Ferguson can assess the extent and pattern of pigment loss and discuss the treatment options that may be appropriate for you. His expertise also includes phototherapy, which can be used to treat vitiligo in suitable patients.
Polymorphic light eruption (PLE) is a skin rash triggered by exposure to sunlight or artificial ultraviolet (UV) light. It falls within photodermatology — the area of dermatology concerned with conditions caused or worsened by light — which is one of Dr Ferguson’s specialist interests. He can assess symptoms that may be caused by PLE and advise on appropriate treatment and ways to reduce future flare-ups.
Dr Ferguson specialises in skin cancer and offers mole checks to assess individual moles or other skin lesions. He also uses 360° mole mapping, which creates detailed images of the skin so that existing moles can be monitored and new or changing lesions identified over time.
If a lesion needs further investigation, Dr Ferguson can perform an excisional biopsy, removing it so that the tissue can be examined under a microscope. Where appropriate, he also performs skin surgery to remove skin lesions.
Dr Ferguson primarily sees adults and teenagers, but he also sees younger children where their skin condition falls within his areas of special interest. If you’re unsure whether Dr Ferguson is the right specialist for your child, please get in touch with our Dermatology centre for further advice.
