| ==Overview==
| |
| '''Nodular melanoma''' (NM) is the most aggressive form of [[melanoma]]. It grows in vertical direction from the outset and grows very fast (months). Nodular melanoma has no known precursor. It is a small black, or if amelanotic, pink nodule that simply enlarges. The lesions tend to bleed.

| ===Microscopic Pathology===
| |
| | |
| The microscopic hallmarks are:
| |
| * Dome-shaped at low power
| |
| * Epidermis thin or normal
| |
| * Dermal nodule of melanocytes with a 'pushing' growth pattern
| |
| * No "radial growth phase"
