Types of Skin Lesions and Their Treatment

A skin lesion also known as a dermal lesion refers to any change in the appearance of the skin as compared to the skin around it. There are two categories of skin lesions that is primary and secondary. Primary skin lesions can be present from birth, hereditary or acquired over time due to skin infection while secondary skin lesions occur when the primary skin lesion is manipulated or irritated.

  • Bulla: it has a large vesicle of over 5mm in diameter.
  • Vesicle: this is a large fluid filled blister that is elevated with well demarcated borders but it is less than 5mm in diameter,
  • Pustule: it contains purulent material and it’s similar in appearance to a bulla or vesicle.

  • Scar: when skin is cut, scraped and scratched is irritated sometimes it does not heal into a healthy normal skin but it instead turns into a thick raised scar known as a keloid.
  • Atrophy: this is fragile and thin skin which is often occurs in elderly people or people who use topical steroids for extended periods.

Treatment for dermal lesions

Treatment for skin lesions depend on the cause and type of lesion. Treatments range from oral medications, topical applications and surgical removal.

Surgical removal

Incase a skin lesion is infected the infection has to be cleared first before opting for surgery. Some of the skin lesions that might require surgical removal are moles which change over time and malformed blood vessels known as hemangioma. They are usually removed through laser surgery.
