Study Notes

Melanoma

Melanoma is a type of skin cancer that appears as asymmetrical brown or black patches with uneven borders and a raised surface.
Treatment for melanoma typically involves surgical excision and immunotherapy.
The ABCDE mnemonic helps diagnose early-stage melanoma.
- Asymmetry: The two sides are not symmetrical.
- Borders: The edges are irregular in shape.
- Color: The color is varied shades of brown or black. '
- Diameter: It is larger than 6 mm (0.24 in).
- Evolving: Its shape has changed.
Nodular melanoma is a serious form with additional signs:
- Elevated: It is raised on the skin surface.
- Firm: It feels hard to the touch.
- Growing: It is getting larger.

Eczema

Eczema is an inflammatory skin condition that can occur at any age.
It appears as dry, itchy patches of skin that resemble rashes.
Symptoms may include swelling, flaking, and in severe cases, bleeding.
Treatment options include moisturizers, corticosteroid creams, and immunosuppressants.

Acne

Acne is a skin disturbance common on areas rich in sebaceous glands, like the face and back.
It is most common during puberty due to hormonal changes but can also occur in infants and adults.
Acne results from the clogging of pores by excess sebum and keratin, leading to infection by Propionibacterium and Staphylococcus.
Infection can cause redness and potential scarring.

Dermatology

A dermatologist is a medical doctor specializing in diagnosing and treating skin disorders.
The field offers lucrative opportunities due to increasing demand for cosmetic procedures, including Botox injections, laser treatments, and dermal fillers.
Dermatologists work in medical offices and may perform simple procedures like mole and wart removal.
They may refer patients to an oncologist if skin cancer that has metastasized is suspected.

Skin Injuries

Skin injuries are common due to the skin's direct contact with the environment.
Injuries can be caused by sharp objects, heat, or excessive pressure or friction.
The healing process involves multiple stages, starting with blood clot formation to stop bleeding and scab formation.
Fibroblasts play a crucial role in repairing damaged tissue by collagen deposition, forming granulation tissue.
Immune cells, such as macrophages, help reduce the chance of infection by engulfing foreign matter.
