An excellent way of identifying changes of significance in a mole is the ABCDE rule: Asymmetry; Border irregularity; Color variegation; Diameter greater than 6 mm (0.24 in); Elevation above surrounding tissue.
dysplastic nevi
Squamous cell carcinoma
basal cell carcinomas
Most moles are benign, but atypical moles (dysplastic nevi) may develop into malignant melanoma, a potentially fatal form of skin cancer. Atypical moles are usually hereditary.
Malignant melanoma may develop anywhere on the body.
The predisposing causes to the development of malignant melanoma are environmental and genetic.
is malignant melanoma dominant or recessive
Malignant melanoma arises in the Stratum basale layer of the epidermal layer.
Malignant melanoma is locally staged based on the depth of penetration through the skin and its appendages.
Malignant degeneration of the melanocyte gives rise to the tumor known as melanoma, which has four subtypes.
skin tumour/cancer
There is also a special type of metastasis that can occur regionally with malignant melanoma; it is known as an in-transit metastasis.
malignant melanoma
Malignant (progressively worsening) Melanoma (tumor) is a type of skin cancer.
The actual number of moles increases risk, but the size of the moles needs be considered. Those with 10 larger moles of over 1 cm (0.4 in.) are at more risk than those with a higher number (50-99) of smaller moles.
