Answer

Answer

Histology of nodular melanomas is characterized by extensive vertical growth into the dermis with a minimal radial component. They comprise approximately 15-30% of melanoma diagnoses. These tumors typically are blue-black but may lack pigment in some circumstances. They are known to arise without a preexisting lesion.
