Test Separates Look-alike Melanoma Subtypes | Melanoma Dispatch | Scoop.it

A new study shows how to distinguish two kinds of non-pigmented melanomas—desmoplastic and spindle cell—that are hard to tell apart. Both cancers often look like tiny scars or dimples in the skin, but spindle cell melanoma tends to spread and be fatal. The researchers tested 38 desmoplastic and spindle cell melanomas for 50 cancer biomarkers and found 4 specific to the former and 5 specific to the latter. Testing for two biomarkers (Melan A and trichrome) was enough to diagnose more than 90% of the samples accurately.
