Birthmarks are skin lesions that are present at birth or they appear just after birth. They can be flat or raised skin lesions. The two main types are:
Vascular birthmarks that appear as red, purple, or bruise-like spots. They occur due to abnormal blood vessels. It includes salmon patches, hemangiomas, and port wine stains.
Pigmented birthmarks appear as tan or brown, raised or flat skin lesions. They occur due to the overgrowth of pigment-forming cells. The common ones are café-au-lait spots, Mongolian spots, and moles.
Cause
The exact cause behind birthmarks is not known.
Treatment
Most of these lesions are harmless and don’t require treatment. However, some may require treatment.
4. Blisters
Blisters are fluid-filled bumps on the skin. Depending on the size, they are called:
- Vesicle (less than 0.5 cm)
- Bulla (more than 0.5 cm)
Cause
Blisters can occur due to friction, pressure, burns, allergic reactions, autoimmune diseases like pemphigus, and infections like herpes.
Treatment
Blisters due to friction and pressure usually heal over time. One should not pop the blisters. The area should be kept clean and if possible covered to protect the blisters.
Autoimmune conditions like pemphigus will require prescription medications.
You should see a doctor if you notice pus or any foul-smelling discharge, fever, or extreme pain.
