Is It a Blood Blister or Melanoma? Skin Lesions

I don't know if this is a blister or melanoma?

Based on the image, it initially appeared to be a petechial hemorrhage (as I often bite it), but I didn't pay much attention until I noticed it had changed after brushing my teeth.
I researched online and found that it could either be a blood blister or something referred to as a melanotic lesion, surrounded by small red spots that seem to have some blood.
However, when I touch it, there are no blood traces on my fingers, and it feels smooth and somewhat sticky.
Blood blisters typically have a round shape, but this one is somewhat irregular.

I looked into melanoma, and it seems that its texture is more similar to skin and tends to become dry.
If it is a blood blister and I don't puncture it, will it persist? I have several blood blisters in my throat as well, and when I consulted an ENT specialist, they mentioned that as long as they don't grow too large or cause significant discomfort, there's no need to puncture them; leaving them alone is harmless unless I experience discomfort.
I still plan to visit a hospital for a check-up, but I would like to ask for an online doctor's opinion.

Observing the image of a blood blister.

However, if it is a blood blister and I do not puncture it, will it continue to exist? Because I have quite a few blood blisters in my throat, and I previously consulted an ENT specialist who said that as long as they do not grow too large or cause significant discomfort, there is no need to puncture them; leaving them alone is harmless unless I experience discomfort.

A: I generally agree with the ENT specialist's opinion.

However, I will still go to the hospital for a check-up, but I would like to ask for the opinion of an online doctor.

A: It’s reassuring to get a check-up; you can also consult a dentist or oral surgeon, as well as the ENT specialist at Taoyuan Hospital.

More Info

When it comes to skin lesions, distinguishing between benign conditions like blood blisters and more serious concerns such as melanoma is crucial. Based on your description and the image you provided, it sounds like you are dealing with a lesion that has changed over time, which is understandably concerning.

Understanding Blood Blisters vs. Melanoma
Blood Blisters: These are typically formed when the skin is damaged, leading to a collection of blood between the layers of skin. They often appear as raised, fluid-filled sacs that can be clear or contain blood. Blood blisters are usually round and smooth, and they can occur anywhere on the body, including areas prone to friction or injury, such as the mouth from biting. They generally resolve on their own without treatment, provided they are not popped or infected.

Melanoma: This is a type of skin cancer that arises from melanocytes, the cells that produce pigment in the skin. Melanomas can appear as new or changing moles and may have irregular borders, multiple colors, and an asymmetrical shape. They can also be firm to the touch and may bleed or crust over. The "ABCDE" rule is often used to assess moles for melanoma:
- Asymmetry: One half does not match the other.

- Border: Irregular, scalloped, or poorly defined edges.

- Color: Varied from one area to another; may include shades of brown or black, or even red, white, or blue.

- Diameter: Larger than 6mm (about the size of a pencil eraser).

- Evolving: Changes in size, shape, or color.

Your Situation
From your description, it seems that the lesion has changed from what you initially thought was a blood spot to something that appears more complex. The fact that it has an irregular shape and is smooth and sticky to the touch raises some concerns. While blood blisters are typically round and smooth, any lesion that evolves or changes in appearance warrants further investigation.

Recommendations
1. Consult a Dermatologist: It is essential to have a dermatologist evaluate the lesion. They can perform a thorough examination and may recommend a biopsy if there are any concerns about the nature of the lesion. This is the most definitive way to determine whether it is benign or malignant.

2. Monitor Changes: Keep an eye on the lesion for any changes in size, shape, color, or texture. If it begins to itch, bleed, or cause discomfort, seek medical attention promptly.

3. Avoid Self-Diagnosis: While the internet can provide useful information, it can also lead to unnecessary anxiety. Rely on professional medical advice for accurate diagnosis and treatment options.

4. Consider Other Lesions: If you have other similar lesions, such as blood blisters in your throat, it may be worth discussing these with your healthcare provider as well. They can help determine if there is an underlying condition that needs to be addressed.

In conclusion, while blood blisters are generally harmless and resolve on their own, any lesion that changes in appearance or does not heal should be evaluated by a healthcare professional. Early detection and treatment are key in managing skin conditions effectively, especially when it comes to potential malignancies like melanoma.
