Brief Answer:
I suggest a dermoscopic examination

Detailed Answer:
Hello. Thank you for writing to us

I have gone through your query and I have also reviewed the Image

I can see a pigmented lesion in this Image.
This looks well defined, has irregular margins, with a darker hue in center as compared to the periphery and seems to have some white areas (at 6 O'clock position and a small spot at center) as well. Can you upload a better quality of image which allows me to appreciate the topograpy more closely and clearly? Or I would suggest a dermoscopic examination for this lesion.

How long has it been there? Has it changed in anyway?in terms of size, color, symmetry? Are there any more such lesions on your skin? Is there a personal or family history of skin malignancy?

Hello, thank you for the reply. It just recently seemed to become darker. I will send you a better picture as well. It seems like it is flat as well. When i rub my finger across it, I do not feel any elevation. I do not have any family history of melanoma either. Given the size of the mole i did not thonk it could be melanoma.

Brief Answer:
I woul rely on dermoscopy for this

Detailed Answer:
Hi.

Thank you. .
The reason I suggest a dermoscopic examination is that it does'nt look perfectly symmetrical in this image, is darker in the center than at the periphery and has changed recently i.e become even darker recently.
Size <5mm and flat lesion are good but still I would suggest a dermoscopic examination to look for its pigment network. This would be more reliable in case of a doubtful lesion.

I recently had an excision for a superficial spreading melanoma, that did start growing veritically, from my upper right shoulder on my back. I still have stitches and am waiting for this pathology to determine if the margins are clear. Since the excision I have veins that are becoming darker blue under that right arm pit, shoulder and chest area. Even after lots of sunblock and reapplication I did get a sunburn, however the joint of my shoulder and armpit meet where one of these dark blue veins are I burnt around the vein but did not burn on nor about 1/4-1/2 an inch all around this vein. Is this normal or something I should contact the doctor who did my excision? I don t want to bother him if unnecessary, but has been a week since excision and have one more week till I go back to see him.

I was diagnosed with Basal Cell Carcinoma, Nodular Type on June 26-2014 I have had a spot by my eye for at least 20 years, really never got any bigger over the years. I m scared to death it might of spread to the brain or somewhere else in the body. My Dermatopathology report say under microscopic description - sections demonstrated a proliferation of atypical basaloid cells extending from the epidermis into the dermis. Peripheral nuclear palisading, stromal mucin deposition and tumor-stromal clefting are observed. The tumor display a nodular growth pattern within the dermis. I m having a Mohs surgery on July 14 -2014 and also scare about how much damage going to be done to my face. I just lost my dad on May 26-2014 to melanoma in the brain only. So has anyone have a basal cell on your face for a long time and what was the outcome. Please any input will be helpful.
