Basal cell carcinoma (BCC): As the most common type of skin cancer, BCC accounts for 80% of all skin cancer diagnoses in the U.S., per AAD. Typically, BCC looks like a skin-colored, translucent ...
Evolution of a 4 mm nodular melanoma. Nodular melanoma (NM) is the most aggressive form of melanoma. [1] It tends to grow more rapidly in thickness (vertically penetrate the skin) than in diameter compared to other melanoma subtypes. [2] Instead of arising from a pre-existing mole, it may appear in a spot where a lesion did not previously exist.
Amelanotic melanoma is a type of skin cancer in which the cells do not make any melanin. [1]: 696 [2] They can be pink, red, purple or of normal skin color, and are therefore difficult to diagnose correctly. They can occur anywhere on the body, just as a typical melanoma can.
Melanoma is the most dangerous type of skin cancer; it develops from the melanin-producing cells known as melanocytes. [1] It typically occurs in the skin, but may rarely occur in the mouth, intestines, or eye (uveal melanoma). [1] [2] In women, melanomas most commonly occur on the legs; while in men, on the back.

Melanocytic tumors of uncertain malignant potential (MELTUMP) are melanocytic lesions in the dermis that cannot be classified by morphology as either benign naevi (moles) or malignant melanomas because the mass shows features of both.
Melanoma is a malignant proliferation of melanocytes and the most aggressive type of skin cancer. [80] [81] [82] Acral lentiginous melanoma Nodular melanoma; Amelanotic melanoma; Animal-type melanoma; Desmoplastic melanoma (neurotropic melanoma, spindled melanoma) Lentigo maligna (lentiginous melanoma on sun-damaged skin) Lentigo maligna melanoma
Nevoid melanoma. A nevoid melanoma is a malignant neoplastic lesion of the skin. It is a type of melanoma, the most dangerous form of skin cancer.Nevoid melanomas are clinically significant because they are difficult to distinguish from a benign nevus of the skin, which requires no treatment and is common on most individuals.
Lentigo maligna is a histopathological variant of melanoma in situ. [6] Lentigo maligna is sometimes classified as a very early melanoma, [7] and sometimes as a precursor to melanoma. [8] When malignant melanocytes from a lentigo maligna have invaded below the epidermis, the condition is termed lentigo maligna melanoma. [2]
