Dermatosis papulosa nigra
Dermatosis paulosa nigra is a condition that occurs mainly in darker skin types and usually starts to form in adolescence. The lesions are small, darkly pigmented papules that are harmless and generally don’t require treatment.
· It appears mainly on cheeks and foreheads
· It often occurs in multiples
· This lesion has a smooth surface
· It appears most likely in an old age
Solar lentigos, also known as “sun spots” or “age spots,” are non-cancerous dark marks or patches on the skin caused by sun damage. Although no treatment is required, patients are often at an increased risk for skin cancer and need to exercise precaution in the sun.
· They consist of dark flat spots or patches
· They usually appear on the face, arms, and shoulders
· They can clump together and range in size from approximately the size of a freckle to 13 millimeters
Sebaceous hyperplasia is a skin condition that occurs when sebaceous gland on the skin is enlarged.
· It appears as small, skin-colored to yellow papules with a central indent
· These papules often occur on the forehead and central face
· They can often resemble basal cell carcinoma, but they rarely bleed or crust
· Removal is not necessary, unless for cosmetic reasons
Milia: tiny epidermoid cysts
Milia or tiny epidermoid cysts is a condition where small 1-2 mm white to yellow papules occur underneath the surface of the skin.
· These cysts can occur in all ages
· They can be extracted without scarring
· They are fixed and long-lasting
· They often occur on the cheeks, eyelids, forehead, and genitalia.
Naevi, the medical term for moles, are common raised or flat spots that occur on the skin genetically and as a result of sun exposure. They form when skin cells called melanocyte cells grow in a group rather than individually. Most moles are benign, but they can also develop into skin cancer.
Harmless moles will have:
· neat edges
· a smooth or dome-like shape
· diameter ¼ inch (6 mm)
· the same shape, size or color over time.
Cancerous moles have a few common warning signs. Look for these indicators that your mole may be cancerous:
· A change in size (getting larger)
· A change in shape (especially with irregular edges)
· A change in colour (especially getting darker or exhibiting multiple shades)
· A loss of symmetry (common moles will be perfectly round or oval and are usually symmetrical)
· Itchiness, pain or bleeding (maybe even forming a scab)
· Exhibiting three different shades of brown or black
· A change in elevation (thickening or raising of a flat mole)

Capillary Haemangiomas, also known as “strawberry birthmarks,” are benign lesions caused by a clumping of tiny blood vessels. They usually appear at six months of life and begin to fade between the age of 12 and 15 months.
· The skin is red and lumpy
· This lesion grows rapidly before slowly fading
· It is found more commonly in females than in males
· Doctors usually allow them to disappear on their own
A papilloma is a wart-like growth that is usually benign but can sometimes be cancerous. Most papillomas are caused by one of 150 human papillomaviruses (HPVs).
· It typically occurs on the genitals, mouth, eyes, and throat
· It can appear as a clumping of bumps on the skin that can be painless or painful
· It can look like flat warts
· It can be rough or smooth
· Some strains of HPVs can cause cervical cancer in women
Seborrheic Keratosis, sometimes called senile wart, is a non-cancerous condition that occurs as a light brown, black or tan growth on the surface of the skin. These are usually harmless but may sometimes get irritated or be aesthetically unappealing. They can be removed if desired.
· The skin is slightly elevated, waxy, and scaly
· Seborrheic Keratosis can occur in all areas of the body, except for the palms and soles
· It often occurs later in life and in multiples
· It often has a stuck, “pasted on” appearance
A fibroma is a tumor-like growth made up of fibrous connective tissue. It’s also called a fibroid or fibroid tumor. Such tumors are often found on the feet, mouth nose or cheek.
· The most common type of fibroma is an angiofibroma, which appears as small fibrous papules on the nose and cheeks
· This type of lesion appears as a lump that is firm to the touch
· It can be itchy or sensitive.
Squamous cell carcinoma
Repeated sun exposure over time usually causes squamous cell carcinoma. This condition is a slow-developing skin cancer that can spread to other areas of the skin, although it is still considered unlikely to spread widely.
· It consists of wart-like bumps that often have crusted surfaces
· It forms rough scaly patches that may bleed
· It can form an open sore that bleeds or develops a crust
· It appears as red, dome-like nodules
