Superficial spreading malignant melanoma

Nodular melanoma (7%)

All body surface, especially the trunk of males. Extremely aggressive, with rapid progression from the radial to the vertical growth phase. Early metastasis, poor prognosis.

Lentigo maligna melanoma (3,5%)

Presents in sun-exposed areas of the body, primarily face, head and neck areas.

Acral lentiginous melanoma (<1%)

Palms, soles and subungual areas

Extremely aggressive, with rapid progression from the radial to vertical growth phase

Rare subtypes

Mucosal lentigo melanoma 

Treatment in the relevant department; e.g, ophthalmic, gynecological and gastrointestinal.

Amelanotic melanoma (<1%)

Subtype of superficial spreading malignant melanoma without sufficient pigment production to appear as a pigmented lesion.

Desmoplastic melanoma (<1%)

Rare type of malignant melanoma characterized by no production of pigment and resemblance to hypertrophic scars. Presents on external skin and must be differentiated from scar-tissue on anamnesis as well as other benign lesions it resembles.
