Atypical mole

I have been experiencing discomfort in my upper left abdomen for quite some time, and I discovered a mole approximately 0.6 mm in size in that uncomfortable area.
I also recently found a symmetrical mole on the opposite side of my upper left abdomen (on my back).
Therefore, I went to the hospital for excision and examination.
The doctor said it is an atypical mole.
I am not sure what an atypical mole is.
Could the discomfort in my upper left abdomen be causing changes in my skin? Since there is also a mole in the same area on my back, should I be concerned after the excision? Thank you.

Hello: Atypical moles are a pathological diagnosis, meaning that a pathologist examines the removed specimen under a microscope and finds that it differs from a typical mole, but it is not considered malignant.
The best management for this type of mole is excision, as it cannot be ruled out that it may become malignant in the future.
This type of mole is very superficial and does not extend into the subcutaneous tissue, so it is unrelated to discomfort in the left upper abdomen.
Whether or not to excise another mole should be determined by the physician who personally examines you.
Wishing you safety.

More Info

Atypical moles, also known as dysplastic nevi, are moles that have an irregular appearance in comparison to common moles. They can vary in color, size, and shape, often exhibiting asymmetry, uneven borders, and multiple colors. While having atypical moles is not uncommon, they can be a concern because they may indicate an increased risk of developing melanoma, a serious form of skin cancer.

The exact causes of atypical moles are not fully understood, but they are believed to be influenced by a combination of genetic factors and environmental exposures, particularly UV radiation from the sun. Individuals with a family history of skin cancer or those who have numerous moles are at a higher risk of developing atypical moles.

Regarding your specific situation, it is important to note that the discomfort you are experiencing in your left upper abdomen is unlikely to be directly related to the presence of atypical moles on your skin. However, it is essential to consider that skin changes can sometimes be a reflection of underlying health issues, although this is not always the case. It is advisable to discuss your abdominal discomfort with your healthcare provider to rule out any potential gastrointestinal or other medical conditions.

After the removal of atypical moles, it is crucial to follow up with your dermatologist or healthcare provider for the results of the biopsy. If the biopsy confirms that the moles are indeed atypical but not cancerous, your doctor will likely recommend regular skin checks to monitor for any new changes or the development of new moles. If there are any signs of melanoma or if the atypical moles show concerning features, further treatment may be necessary.

In terms of post-operative care, it is essential to keep the surgical site clean and monitor for any signs of infection, such as increased redness, swelling, or discharge. Additionally, protecting the area from sun exposure is vital, as UV rays can affect healing and increase the risk of skin cancer.

In conclusion, while atypical moles can be a cause for concern, they do not necessarily indicate an immediate health threat, especially if they are monitored and managed appropriately. It is crucial to maintain open communication with your healthcare provider regarding any symptoms you experience, including abdominal discomfort, and to adhere to follow-up appointments for skin monitoring. Regular skin examinations and being vigilant about changes in your skin can significantly contribute to early detection and prevention of skin cancer.
