Major Functions of the Skin
- Perceiving touch, pressure, temperature and pain via nerve endings
- Protection against mechanical, chemical, thermal, and solar damage
- Protecting against loss of water and electrolytes
- Regulating body temperature
- Repairing surface wounds through cellular replacement
- Synthesizing vitamin D
- Allowing identification through uniqueness of facial contours, skin and hair color, and fingerprints

It is a bright red birthmark that shows up at birth or in the first or second week of life. It looks like a rubbery bump and is made up of extra blood vessels in the skin.
Hemangioma
can occur anywhere on the body, but most commonly appears on the face, scalp, chest or back, treatment isn’t usually needed as it fades away over time.

Spider (star) angioma
It is a small, dark blue to purple slightly elevated papules. These papules are soft and compressible. They commonly appear on sun-exposed areas such as the face, lips, ears, neck and back of the hand of elderly people. These little purple papules are typically asymptomatic, causing no pain or symptoms. They are benign, but often are confused with melanoma
Venous lake
These arepinpoint, round spots that appear on the skin as a result of bleeding. They can be caused bya simple injury, straining or more serious conditions The bleeding causes this to appear red, brown or purple.
Petechiae
What causes Petechiae to appear red, brown or purple?
Bleeding
It is also called blood spots or skin hemorrhages, refers to purple-colored spots that are most recognizable on the skin. The spots may also appear on organs or mucous membranes, including the membranes on the inside of the mouth.
Purpura
Two main types of Purpura related to Blood Platelet Levels
-Thrombocytopenic Purpura (Low platelet count)
-Non-Thrombocytopenic Purpura (Platelet count is in normal range)
It is s the medical term for a bruise. A bruise, or contusion, is skin discoloration from damaged, leaking blood vessels underneath your skin.
Ecchymosis (bruise, contusion)
It is generally defined as a collection of blood outside of blood vessels.
Hematoma
defined as a solid swelling of clotted blood within the body’s tissues.
hematoma
is a skin discoloration that results from bleeding underneath the skin.
Ecchymosis
It is also known as ring worm. It is a rash caused by a fungal infection. It’s usually an itchy, circular rash with clearer skin in the middle. Ringworm gets its name because of its appearance. No worm is involved.
Tinea corporis
It often spreads by direct skin-to-skin contact with an infected person or animal.
Ringworm
Ringworm of the Foot or Athletes foot

Rubella
Is Rubella caused by the same virus as Rubeola?
No
How does Rubella Spread
Through breathing in virus infected fluid
It is an infection caused by the varicella-zoster virus. It causes an itchy rash with small, fluid-filled blisters
Chickenpox (varicella)
Virus of Chicken Pox
Varicella-zoster
t is a virus that causes skin infections. The infection lasts your lifetime, and it causes painful or itchy sores and blisters that come and go.

Basal cell carcinoma
It is a common form of skin cancer that develops in the squamous cells that make up the middle and outer layers of the skin.
Squamous cell carcinoma
It is the most serious type of skin cancer, develops in the cells (melanocytes) that produce melanin — the pigment that gives your skin its color.
Malignant melanoma
It is a disease in which cancer cells are found in the skin or mucous membranes that line the gastrointestinal (GI) tract, from mouth to anus, including the stomach and intestines.These tumors appear as purple patches or nodules on the skin and/or mucous membranes and can spread to lymph nodes and lungs.
Kaposi’s sarcoma
caused by an infection with a virus called human herpesvirus 8, which is also known as Kaposi sarcoma-associated herpesvirus (KSHV)

Loss Of Color in skin due to absence of oxygenated Hemoglobin.
Wide spread but most apparent in face, mouth, conjunctivae, and nails
Pallor
Pallor appearance in dark skin
- Black skin loses its red undertones appearing ash gray
- Brown skin becomes yellow tinged
Pallor appearance in light skin
- White skin loses its rosy tones.
- Skin with natural yellow tones appears more yellow may be mistaken for mild jaundice
Possible Causes of Pallor
- Sympathetic nervous stimulation resulting in peripheral vasoconstriction due to smoking
- a cold environment
- stress
- lack of oxygen
- decreased tissue perfusion
- anemia
Congenital or acquired loss of melanin pigment.
Absence of Color
Possible causes of Absence of color (Generalized Depigmentation)
- Albinism
- vitiligo
- tinea versicolor
- a common fungal infection
Appearance of Absence of Color (General Depigmentation) on light skin
- Albinism appears as white skin, white or pale blond hair
- Vitiligo appears as patchy milk white areas especially around the mouth
- Tinea versicolor appears as patchy areas paler than the surrounding skin
Appearance of Albinism on Dark skin
- appears as white skin
- white or pale blond hair
- pink irises
- vitiligo is very noticeable as patchy milk-white areas
- Tinea versicolor appears as pale patchy areas
Mottled blue color in skin and its appendages due to inadequate tissue perfusion with oxygenated blood. Most apparent in the nails, lips, oral mucosa, and tongue
Cyanosis
Possible causes of Cyanosis
Systemic or Central Cyanosis
- Cardiac disease
- Pulmonary disease
- Heart Malformation
- Low Hemoglobin levels
Localized or Peripheral Cyanosis

- exposure to cold
- emotional stress
Appearance of Cyanosis on Light skin
-Skin lips and mucous membranes look blue tinged
-The conjunctivae and nail beds are blue
Appearance of Cyanosis on Dark skin
