What is the difference between melanoma and malignant melanoma?
Melanoma is a cancer that begins in the melanocytes. Other names for this cancer include malignant melanoma and cutaneous melanoma. Most melanoma cells still make melanin, so melanoma tumors are usually brown or black. But some melanomas do not make melanin and can appear pink, tan, or even white.
Is Stage 1 melanoma serious?
Stage 1 is considered a 'thin melanoma'. If your melanoma is caught before it is too thick the prognosis is very good. Nearly 19 in 20 people who have a stage 1 melanoma are alive at least five years after being diagnosed. Stage 1 is the least serious type of melanoma.

What age do you get melanoma?
While anyone can develop superficial spreading melanoma, some are more likely to than others. Things that make you more likely to develop it include: 1 Middle age: It tends to occur most often in people in their 40s and 50s. 2 Light-colored skin: As with other skin cancers, people with fair skin are most at risk for developing superficial spreading melanoma. This is likely because fair skin has less melanin, a skin pigment that can help protect the skin from harmful UV rays. 3 UV exposure: It tends to occur in the back, chest, and legs, which are all likely to get intense, periodic UV exposure from the sun. Getting sunburns at an early age and UV exposure from tanning beds also increase your risk. 4 Having a lot of moles: Since many cases develop within moles, the more moles you have, the greater your chance of having superficial spreading melanoma. People with 50 or more moles have a greater risk of melanoma, according to the American Skin Association. 5 Family history: While it isn’t inherited, some of the gene mutations responsible for superficial spreading melanoma are. The BRAF gene, which can allow cancer cells to grow freely, may play a role in melanoma.

What is the best way to diagnose a skin lesion?
In the majority of cases, the dermatologist will first use a dermatoscope in order to take a better look at the lesion and then he will most likely recommend what is known as an excisional skin biopsy. The biopsy will be able to determine whether there are malignant cells or not.
What are the causes of melanoma?
Besides the actual causes that lead to the appearance of this skin condition, there are certain risk factors that can add their contribution to the problem. These are: 1 Age – as the superficial spreading melanoma develops over several decades, it seems that old age is a risk factor (however, the lesion has existed for some time and only then it was noticed and diagnosed). 2 Existence of invasive melanoma or melanoma in-situ – patients who have already been diagnosed with such problems stand a high chance of receiving the same diagnosis all over again. 3 Existence of other types of skin cancer 4 Numerous moles of various colors and forms present on the skin. This becomes an even more obvious risk factor if there is constant and prolonged sun exposure 5 Family history of melanoma 6 Light skin and light colored eyes
What is the initial phase of melanoma?
In the initial phase, the superficial spreading melanoma grows on the surface of the skin in an horizontal manner.

A doctor will often use a dermascope to diagnose melanoma. This tool will help a doctor identify distinguishing critical features of a mole or skin lesion that has evolved into superficial spreading melanoma.
What is the forming cluster of melanoma?
The forming cluster is the basis of the malignant patch, which will eventually spread across the top layers of skin. The melanoma often begins from an irregular mole, also known as a dysplastic nevus. Approximately 25% of cases arise from an existing mole, while the rest derive from a new mole.
How to identify dangerous moles?
Dangerous moles can be recognized using the ABCDE self-check method. This method shows you which signs to look out for when examining suspicious moles, spots or growths on your skin. The Melanoma Research Foundation provides a handy overview of the method you can reference when performing skin checks.
What is the most common type of melanoma?
Superficial spreading melanoma is considered the most common type of melanoma. It is classified as in situ, which means that it occurs in the uppermost layers of skin.
Where does melanoma spread?
Superficial spreading melanoma occurs when melanocyte cells (the cells that produce melanin, which gives color to our skin) begin clustering together in the lowest layer of the epidermis known as the basal layer. The forming cluster is the basis of the malignant patch, which will eventually spread across the top layers of skin.
What is superficial spreading melanoma?
Superficial spreading melanoma derives its name from its robust intraepidermal growth (RGP) and is thought to be the most common variant of melanoma affecting predominantly Caucasians without gender predilection. The most common sites are the back in males and the leg in women. In its early stages, it may present as a scaly macule or patch (i.e., intraepidermal growth), which will develop a gray to black nodule (i.e., invasive growth) after a variable period. Depigmented (amelanotic) variants may be observed as erythematous or scar-like plaques. Scalloping of the border and color variegation are characteristic features. Prominent epidermal infiltration by malignant melanocytes (pagetoid spread) may lead to epidermal effacement and ulceration. The histopathologic features are highlighted in Figure 19. During the RGP, superficial spreading melanoma shows an intraepidermal proliferation of malignant melanocytes throughout all epidermal layers, called pagetoid spread because of its resemblance to Paget's disease (a mucinous carcinoma that typically infiltrates through the epidermis). The cells are usually epithelioid with large, pleomorphic, and hyperchromatic nuclei and prominent nucleoli. Expansive nests occupy the dermis and typically have the same morphological attributes as the intraepidermal component, facilitating distinction from the not infrequent associated nevus. The epidermis may be thickened and the rete ridge pattern effaced. Lymphovascular invasion may be seen in thicker lesions but neural invasion is uncommon.
What is SSM in melanoma?
SSM is the type of melanoma for which the ABCD rule for clinical melanoma diagnosis is most useful. A symmetry, with irregular b order, multiple c olors, and d iameter greater than 6 mm are clinical features that suggest melanoma ( Fig. 13.1 ). 3 Many of the 10 melanoma-specific dermoscopic structures are most relevant to identification of SSM. This includes atypical pigment network, streaks, irregular blotches, and peripheral brown structureless areas ( Table 13.1 ). The other structures such as negative pigment network, chrysalis, atypical dots and globules, blue white structures, and atypical vascular structures may be seen in SSM but are also frequent in other subtypes of melanoma ( Figs. 13.2–13.4, see also Fig. 13.1 ).

Lentigo maligna melanoma, superficial spreading melanoma, and acral lentiginous melanoma are characterized by a horizontal growth phase that allows for clinical identification before deeper invasion and metastasis occur.
What is LM skin?
2. Lentigo maligna (LM): Melanoma in situ (limited to epidermis) of sun-exposed skin with solar elastosis. If a melanoma in situ does not have solar elastosis, then it is simply called melanoma in situ, and is not called LM. LM is pigmented macule usually on face or sun-exposed skin.
Why is melanoma called pagetoid spread?
During the RGP, superficial spreading melanoma shows an intraepidermal proliferation of malignant melanocytes throughout all epidermal layers, called pagetoid spread because of its resemblance to Paget's disease (a mucinous carcinoma that typically infiltrates through the epidermis).
What is the most common type of melanoma?
Superficial spreading melanoma is the most common type of melanoma on skin and mucous membranes, accounting for approximately 80% of all lesions.

What is a nodular melanoma?
Nodular melanoma is an invasive form of melanoma characterized by relatively rapid vertical growth. Melanomas that arise in the eye are known as uveal, or ocular, melanomas. Melanoma, known as mucosal melanoma, can also arise from mucosal surfaces such as the lips, eyelids, vulva, penis or anus.
What is the second most common type of melanoma?

What is a lentigo maligna?
Lentigo maligna melanoma. These melanomas develop from very slow growing coloured patches of skin called lentigo maligna or Hutchinson's melanotic freckle. The lentigo maligna is flat and grows outwards in the surface layers of the skin. It might slowly get bigger over several years and might change shape or colour.
How common is melanoma?
It's the most common type of melanoma. 60 to 70 out of every 100 people with melanoma (60% to 70%) have this type of melanoma. It’s most often diagnosed in people aged between 30 and 50 years. It can develop anywhere on the body. But in men it's most common on the central part of the body (the trunk). And in women, it is most common on the legs.
Where is a lentiginous melanoma found?
Acral lentiginous melanoma. Acral lentiginous melanoma is usually found on the palms of the hands and soles of the feet or around the big toenail. It can also grow under the nails. It is much more common on the feet than on the hands.
Where does melanoma start?
Melanoma usually develops in the skin and is called cutaneous melanoma (cutaneous means skin). But rarely, it can start in the mucous membrane - this is the layer of tissue that covers the inside surface of parts of the body such as the mouth or vagina. This type of melanoma is called mucosal melanoma.
Is melanoma a dark pigment?
Melanin is a dark coloured pigment. So unlike other melanomas, amelanotic melanomas are usually red or skin coloured rather than dark coloured. Other types of melanoma such as acral lentiginous can lack colour and are amelanotic melanomas. This type of melanoma is rare.
What is a nodular melanoma?
Nodular Melanoma. This type of invasive melanoma comprises approximately 10-15% of all melanomas. Instead of having a horizontal growth phase like a superficial spreading malignant melanoma, this has a quicker vertical growth phase meaning that the tumor invades the dermis at a faster rate. Therefore, the tumor often is deeper at the time ...
What is the earliest form of melanoma?
An abnormal horizontal growth of these cells results in the earliest form of melanoma which is called melanoma in situ. Because this form of early melanoma is confined to the top layer of the skin and has no contact with blood vessels or lymphatic vessels, there is no risk of the tumor spreading.
What is the most common type of melanoma in African Americans?
Acral Lentiginous Malignant Melanoma. This type accounts for less than 5% of all invasive malignant melanomas. It is the most common type of melanoma in African Americans and Asians. It develops on the palms and soles as well as the nail beds.
Can melanoma spread to other sites?
This term means that the site of origin of the melanoma cannot be determined and that the tumor has already spread (metastasized) to other internal body sites. This occurs with melanomas that have regressed and with melanomas that have arisen in internal sites such as the gastrointestinal tract or spinal column.
