Please tell me if a lentiginous junctional dysplastic nevus is really melanoma in situ. My doctor won't respond.

Please tell me if a lentiginous junctional dysplastic nevus is really melanoma in situ. My doctor won't respond.

There is a subtle di: Melanoma in situ is different than a dysplastic nevus, but it is a continuum. They both need to be treated in the same manner, re-excision with a negative margin. But remember one is a cancer the other one is a precursor of cancer. So it has long term health implications for health insurance etc. ...Read more

Skin Cancer (Definition)

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

What is dysplastic nevus as compared to melanoma?

What is dysplastic nevus as compared to melanoma?

You have asked...: ...One of the most controversial questions in dermatology. One faction believes that dysplastic nevi are precursors of melanomas, and should be excised before they become melanomas. Another faction believes dysplastic nevi are benign moles that never become melanomas. There is evidence to support both arguments. ...Read more

Which disease has more severe consequences dysplastic nevus or melanoma?

Melanoma: A dysplastic nevus, unlike a melanoma, is not a true cancer. It is best thought of as a pre-cancer, a possible precursor to melanoma that with time may possibly be able to turn into a true cancer like melanoma. ...Read more

25%: We remove them if we suspect they are malignant. There is rarely any benefit from removal of benign "dysplastic" nevi. All recent studies indicate that your omega 3 is a waste of money. Aspirin may reduce the risk of skin cancers, including melanoma. The dose is 81mg (baby aspirin). If your aspirin is coated, throw it away. It must be uncoated to be effective. Get CHEWABLE baby aspirin. Can swallo ...Read more

What is the likelihood of a dysplastic nevus turning into melanoma? I can't find any relative data online

Depends: It depends on several factors, like the total # of dysplastic nevi, nevi size, patient age, family history, etc. The reported annual transformation rate of any single mole into melanoma is ≤1 in 200, 000 in people 60. Check out this paper by Tsao H, et al, in Archives of Dermatology in 2003: The Transformation Rate of Moles (Melanocytic Nevi) Into Cutaneous Melanoma. ...Read more

How often does dysplastic Nevus turn into melanoma? What percent will actually become malignant? Thanks

Depends on grade: Excisional biopsy of dysplastic nevi with moderate-to-severe and/or severe dysplasia can be of benefit because of the association and potential conversion to malignant melanoma. It is suggested that excision of biopsy-diagnosed DN with mild or moderate dysplasia has less of a benefit with minimal evidence of conversion to invasive melanoma. ...Read more

Dysplastic nevus, or atypical moles, and they are benign lesions that resemble early melanoma, and about 1 in 10 million americans willmelanoma, what to do?

Watch carefully: Dysplastic nevi are potentially serious in that they can convert to infiltrating melanoma. In children with spitz nevus, they look malignant but never convert. In patients with neurofibromatosis there is a high incidence of dysplastic nevi and since many are present they are watched for changes in shape, darkening in color or redness around the lesion suggesting that they are converting. ...Read more

Low risk: As long as the atypical nevus was excised with negative margins (normal skin at all edges), then you should be fine. Lower your risk of developing a new problem somewhere else by avoiding excessive sun exposure, or by using frequent applications of sunscreen if you must be out in the sun. ...Read more

Can a recurrent Nevus be misdiagnosed as melanoma or dysplastic if the pathologist is not aware of previous biopsy or laser ablation?

Can a recurrent Nevus be misdiagnosed as melanoma or dysplastic if the pathologist is not aware of previous biopsy or laser ablation?

False DX of melanoma: When a benign or dysplastic nevus grows back after biopsy, and is re-biopsied or excised, it may now show features that closely mimic a melanoma under the microscope. This melanoma-like pattern is called "recurrent nevus phenomenon." A pathologist might accidentally misdiagnose a benign, recurrent nevus as melanoma, if they don't know (or don't suspect) it was previously biopsied. ...Read more

DYSPLASTIC NEVUS: THIS IS A NEVUS (MOLE) WITH AN ABNORMAL DEVELOPMENT OR GROWTH OF CELLS.
THIS SHOULD BE SEEN BY A DERMATOLOGIST WHO WILL DECIDE WHETHER TO EITHER WATCH IT PERIODICALLY OR TO CUT IT OUT -- BIOPSY IT -- UNDER LOCAL ANESTHESIA AND THEN SEND THE SAMPLE TO A SPECIALIZED PATHOLOGIST FOR AN EXAMINATION. ...Read more

What happens in dysplastic nevus syndrome?

Close monitoring: Dysplastic nevus syndrome is a condition in which the person has many (often 100's) atypical moles. With the syndrome, one has a higher risk of developing malignant melanoma, which is a high risk skin cancer. For this reason, frequent and close monitoring with self skin checks and routinely by a dermatologist is a must. ...Read more

Is it a common thing to have a dysplastic nevus?

In Certain families: A dysplastic nevus is the term for a biopsy appearance of the pigmented lesion under the microscope - cells with atypia. The lesion itself to the naked eye or under magnification has asymmetry, irregular border, & different pigment colors. Only with pathology can one be sure that the nevus has not become an active melanoma. Families with many dysplastic nevi are at increased risk of melanomas. ...Read more

Do all dysplastic moles eventually turn into melanoma?

Do all dysplastic moles eventually turn into melanoma?

No, they do not: Dysplastic nevi are considered a marker for melanoma risk but not a precursor lesion. Most melanomas arise on normal skin, not in a mole. Sometimes moles do develop melanoma & they start changing, one of the things we look for when suspecting melanoma. We look for abcde asymmetry, border irregularity, color irregularity & change or evolution in melanoma. Any changing mole needs to be seen by derm. ...Read more

New 'mole'. How fast can a new mole become dysplastic nevus? I had one severe. On back so I cannot view well.

Have examined: There is no way to know without looking at it. Have an experienced dermatologist examine you and decide if it needs to be biopsied. If you have already had a severe dysplastic nevus, your chances of having another one are increased. ...Read more
