While some cases may have dermoscopic clues (eg atypical pigment network, white lines, streaks, irregular globules, blue-white veil, atypical vascular structures) others may not, accordingly a nodular melanoma should be in the differential diagnosis of any firm growing nodule or plaque of uncertain diagnosis. Diagnostics of the nodular melanoma Differential diagnosis is important, which allows to distinguish one type of wart from another, as well as to identify the exact species and generic name of the virus that caused the development of pathology.
