Scalp melanoma has been recognised as an uncommon but clinically significant entity in the literature; this diag- nosis is associated with a poorer prognosis. Even after accounting for common prognostic factors (thick Breslow, positive sentinel lymph node, presence of ulceration, older age and male gender) they had significantly worse 5-year melanoma specific survival and overall survival rates of
24% lower than other melanoma sites. We propose late diagnosis related to the difficulties of a scalp examination is a significant factor contributing to the poorer prognosis. The literature does not clearly outline a protocol for scalp examination, but rather focuses on trichoscopy. We will present a comprehensive scalp examination protocol with a focus on melanoma and keratinocyte cancer, and a novel observer-based technique to facilitate re-identification of scalp lesions with efficiency and precision as developed by a Dermatologist with over 30 years of experience.
