Types of malignant melanoma:
- Superficial spreading melanoma: this type appears as a brown or a black lesion, flat or slightly raised that may show irregular borders and color variegation. It’s the most common type of melanoma in whites and most often appears on the upper arm and back in men and on the legs in women. This type spread initially through the epidermis which is the top layer of the skin, it can spread to the other layers of the skin (dermis and subcutaneous tissue) or even other parts of the body if it’s not diagnosed and treated early.
- Nodular melanoma: this type of melanoma spreads quickly therefore it’s the most aggressive type; it appears as a rapidly enlarging lump that is usually black in color. It may ulcerate and present as a non healing skin ulcer.
