Actinic Keratosis (Facial)
Actinic Keratosis also known as Solar Keratosis is a premalignant condition of thick and crusty patches of the skin. It is associated with those who are frequently exposed to the sun. Untreated lesions have up to 20% risk of progression to squamous cell carcinoma.1,2,3,4

Cervical Contact Bleeding
Cervical contact bleeding is bleeding which originates from the cervix. There are several potential causes for bleeding from the cervix, and women are usually encouraged to go to a gynaecologist for evaluation if they experience cervical bleeding. Cervical bleeding after copulation or another contact with the cervix is relatively common and may result from a wide range of non-cancer-related pathologies, such as cervical polyps, various metaplastic states. 1,2,3,4

Gingival Melanin Pigmentation
Gingival Melanin Pigmentation (GMP), which is benign however a cosmetic concern, is a focal pigmentation of endogenous origin that occurs as a result of the excessive deposition of melanin. The color of the oral melanin pigmentation may vary from light to dark brown or black, depending on the amount and localization in the tissue. 1

Seborrheic Keratosis
Seborrheic Keratosis (also known as Seborrheic verruca and Senile wart) is a wart-like noncancerous benign skin growth that originates in keratinocytes. 1,2,3

Lentigo (Facial & Non-facial)
Lentigo is a small pigmented spot on the skin with a clearly-defined edge, surrounded by skin of normal appearance. It is a benign hyperplasia of melanocytes which is linear in its spread. It is most commonly seen in older adults, particularly those who sunburn easily and who fail to tan. 1

Molluscum Contagiosum
This is a benign skin lesion caused by virus of the Mollusca genus and involves a benign, self- limited papular eruption of multiple umbilicated, cutaneous tumours known as Molluscum Contagiosum. This common viral disease is confined to the skin and mucosal membranes. Transmission requires direct contact with infected hosts or contaminated fomites. It is generally thought to exclusively infect humans, but there are a few isolated reports of Molluscum Contagiosum occurring in other animals. The infection is found worldwide and has a higher incidence in children, sexually active adults, and those who are immunodeficient. 1,2

Verruca Plana
Warts can appear more often if the body’s immune defence system is weak. Children and adolescents are particularly likely to be affected, as they have not (yet) built up antibodies to the virus and have more frequent contact with other wart carriers through contact games and from hand to face or to elbows and knees through minor abrasion. 1,2

Verruca Plantaris
Warts can appear more often if the body’s immune defence system is weak. Children and adolescents are particularly likely to be affected, as they have not (yet) built up antibodies to the virus and have more frequent contact with other wart carriers through contact games and from hand to face, sometimes to elbows and knees through minor abrasion. 1,2
