Overview
Types of primary melanoma
The most common types of Melanoma in the skin:
- superficial spreading melanoma (SSM)
- nodular melanoma
- acral lentiginous melanoma
- lentigo maligna (melanoma)
Any of the above types may produce melanin (and be dark in colour) or not (and be amelanotic - not dark). Similarly any subtype may show desmoplasia (dense fibrous reaction with neurotropism) which is a marker of aggressive behaviour and a tendency to local recurrence.
Elsewhere:
- clear cell sarcoma (Melanoma of Soft Parts)
- mucosal melanoma
