Pet Melanoma Diagnosis
Metastases: PET CT is often utilized to identify metastases from melanoma. Utilizes isotope F18 FDG for glucose metabolism of malignant lesions to identify them. Most malignant neoplasms have increased metabolic activity. CT portion compares anatomic lesion with area of increased uptake shown by PET. Read moreSee 2 more doctor answers
A condition in which some element of your skin--which is one of the most complex organs in the body--degenerates into cancer. The three most common types of skin cancer are: basal cell, squamous cell, and melanoma which occur in that order and degree of aggressiveness. Although heredity plays a major role, sun exposure and tobacco use and ...Read more

Pet scan 3-4mm, suv value of 1, no further evidence of disease, before surgery melanoma 0.8 mm negative sln, blood samples normal, no other signs?
What would cause a pet scan to not detect malignant melanoma that was about the size of a chocolate easter egg? I also have type II diabetes.
No test is always right, pet/ct included. Every patient's tumor is unique, too. How a particular tumor will take up the primary pet/ct tracer, called f-18 fdg, is also not perfectly known. Some consistently fail to take up FDG that pet/ct is rarely used to image them, but this is not true for melanoma.
Finally, smaller tumors are always harder to see, no matter which imaging technique is used. Read more
Diagnosed- malignant melanoma 5/2017 Diagnosed - treated for anal cancer 5/2016. Pet scan done in March '16. If MM has spread, wouldn't PET scan show?
PET scan is a good t: PET scan is a good test to detect metastatic cancer. In fact it is our best imaging test to catch metastases early. Yet it has some limitations in that it can not show microscopic tumors/ small # of cells in the body...it only shows tumors that are bigger than half a centimeter (>5 mm). That is why this test has to be repeated every 3 to 4 months when there is a risk for the tumor to come back. Read more
My husband has a melanoma on the right side of his stomach. Blood work, X-ray and pet scan are normal. Does that mean it is not nessery for a node biopsy?
My father has metastatic melanoma, 1 lymph node involvement. Pet scan and CT scan shows no other metastasis at this time. Does this mean he is cured?
Melanoma...: Melanoma is a very tricky disease and must be followed closely. It can metastasize to odd places. It is good news that only 1 lymph node is seen on pet/ct rather than many lymph nodes but one should note that micrometastases or very small lesions may be below the resolution of pet imaging.

What does "atypical intraepidermal melanocytic proliferation, suggestive of melanoma in situ" mean in diagnosis?
I did a search for diagnosis of some of my symptoms and came up with melanoma. What do doctors look for to diagnose it?
Skin exam &biopsy: Melanoma is diagnosed by performing a complete skin exam and by taking a sample (biopsy) of the suspicous areas. The skin biopsy is then examined under a microscope to determine if it is melanoma. See the picture to find out what typical melanoma moles look like. Read moreSee 1 more doctor answer
If nodular melanoma was picked off. Would a biopsy of the underlying tissue a few months later still be accurate to make a diagnosis.
I am a 25 year old female with a history of melanoma on the abdomen 6 years post diagnosis the tumor was very small and it was stage 1 my treatment co?
Picked off mole (maroon, black tissue initially mistook as blood blister)what I realized later looked exactly= Nodular melanoma. Would bx still be accurate for diagnosis since I picked off visible lesion.
Biopsy needed: Yes, if this is in fact a melanoma, a biopsy would still show it even though you pulled off the top layer. If it's not a melanoma, a diagnosis could still possibly be made. It would be uncommon for you to be able to simply pull off a melanoma however. See your dermatologist to be sure. Read moreSee 2 more doctor answers
Skin malignancy: Malignant melanoma is a highly malignant skin tumor, that if not brought under control by early surgical removal will metastasize to almost every organ in the body. Most important factor for aggressiveness was first Clarks level measuring depth of penetration but later changed to Breslows classification for thickness. Lesion less than 1mm favorable, more than 2 mm. Not good. Read more
Type of skin cancer: Melanoma is a very dangerous form of skin cancer, caused by the pigment producing cells of the skin. The skin is not the only place that melanomas form, because melanocytes (the cells that go bad) occur in many areas of the body. Skin melanoma is on the increase, but our ability to catch it early is also improving. If you have a changing skin mole, get it examined! Read more
