See more images of superficial spreading melanoma Dermoscopy of superficial spreading melanoma. Superficial spreading melanoma may be suspected clinically, aided by dermoscopy and reflectance confocal microscopy, and confirmed on skin biopsy usually excision biopsy.

If the skin lesion is suspicious of superficial spreading melanoma, it should be cut out excision biopsy. A partial biopsy is best avoided, except in unusually large lesions where multiple punch biopsies may be required. A single incisional or punch biopsy could miss a focus of melanoma arising in a pre-existing naevus. The pathological diagnosis of melanoma can be difficult in very early lesions. Histological features of superficial spreading melanoma include the presence of buckshot pagetoid scatter of atypical melanocytes within the epidermis.

These cells may be enlarged with unusual nuclei. Dermal invasion results in melanoma cells within the dermis or deeper into subcutaneous fat. The pathologist 's report should include a macroscopic description of the specimen and melanoma the naked eye view , and a microscopic description. The following features should be reported if there is invasive melanoma. The Breslow thickness is reported for invasive melanomas.

It is measured vertically in millimetres from the top of the granular layer or base of superficial ulceration to the deepest point of tumour involvement.

It is a strong predictor of outcome; the thicker the melanoma, the more likely it is to metastasise. The deeper the Clark level, the greater the risk of metastasis secondary spread. It is useful in predicting outcome in thin tumours , and less useful for thicker ones in comparison to the value of the Breslow thickness.

Those with melanoma that is more than 0. And no tests are thought necessary for healthy patients who have remained well for 5 years or longer after removal of their melanoma, whatever stage.

Melanoma staging means finding out if the melanoma has spread from its original site in the skin. Not all superficial spreading melanomas require formal staging with investigations. In this stage, cancerous cells are only on the outer layer of skin. Your doctor may recommend minor surgery to remove the cancerous cells and keep them from spreading. Stage I. Cancer cells have begun to spread beneath the skin.

Stage II. Your doctor will recommend surgery, a lymph node biopsy, and may recommend medication or immunotherapy. Stage III. The melanoma tumor has spread to nearby lymph nodes and is at risk of metastasizing to other parts of the body. At this stage, your doctor will recommend surgery and another type of treatment, like chemotherapy, radiation, or immunotherapy.

Stage IV. Stage IV is the most serious and difficult to treat form of melanoma. In this stage, the tumor has metastasized to other parts of the body. In addition to surgery, your doctor may suggest aggressive treatments like chemotherapy, radiation, or immunotherapy. In some scenarios, you may even be recommended to take part in a clinical trial.

Ask your doctor what kind you will need. Each type has pros and cons. The choice of which type to use depends on your own case. Lab tests of biopsy samples: If melanoma is found, lab tests might be done on the cancer cells to see if they have certain gene changes. This might affect your treatment options. Chest x-ray: This test may be done to see if the melanoma has spread to your lungs. Ultrasound: This test uses sound waves and their echoes to make pictures of the inside of your body.

Ultrasound might be used to look at lymph nodes small collections of immune cells near the tumor to see if the cancer has spread there. A CT scan may be used to see if nearby lymph nodes are swollen or if organs like the lungs or liver have spots that might be from the spread of melanoma.

If any spots are found, a CT scan might be used to guide a needle into the spots to do a biopsy. MRI scan: This test uses radio waves and strong magnets instead of x-rays to make detailed pictures of your insides.

It's very good for looking at the brain and spinal cord. This test can help show if the cancer has spread. PET scan: PET scans use a special kind of sugar that can be seen inside your body with a special camera. This test can help show if and where the cancer has spread.

If you have melanoma, the doctor will want to find out how far it has spread. This is called staging. Your doctor will want to find out the stage of your cancer to help decide what type of treatment is best for you. The stage describes the growth or spread of the melanoma through the skin. It also tells if it has spread to other parts of your body. Your cancer can be stage 0, 1, 2, 3, or 4. The lower the number, the less the cancer has spread. A higher number, like stage 4, means a more serious cancer that has spread beyond the skin.
