JENIS JENIS UKK (Basic Dermatology & Venerology Examination)

Summary

This video discusses skin disorders, specifically categorized into primary and secondary skin lesions (UKK). Primary lesions are caused directly by the disease, while secondary lesions arise due to natural disease progression or infection. The video covers various types of lesions, such as macules, papules, nodules, and vesicles, and explains their characteristics and associated diseases. It also describes secondary lesions like scales, crusts, lichenification, and atrophy. Overall, the video provides an informative guide to recognizing and understanding skin abnormalities, aiding in the diagnosis and treatment of various skin conditions.

Takeaways

• 😀 UKK (Skin Abnormalities) are classified into two types: primary and secondary.
• 😀 Primary UKK refers to skin changes caused directly by the main disease, while secondary UKK occurs after natural disease progression or as a result of scratching or infection.
• 😀 Primary UKK includes four major categories: flat lesions, elevated lesions, lesions with skin integrity damage, and other types that don't fit these categories.
• 😀 Flat lesions are further classified into macules (less than 1 cm) and patches (larger than 1 cm), such as those found in vitiligo.
• 😀 Elevated lesions containing solid tissue include papules (less than 1 cm), nodules (more than 1 cm), and plaques (larger than 1 cm), with examples like syringoma and tinea corporis.
• 😀 Elevated lesions with fluid content can be vesicles (less than 1 cm), bullae (larger than 1 cm), or pustules (less than 1 cm), seen in conditions like herpes zoster and psoriasis pustulosa.
• 😀 Lesions with skin integrity damage are classified into erosions (affecting only the epidermis) and ulcers (affecting the dermis).
• 😀 Other primary UKK include urticaria (hives), cysts, scars, comedones (characteristic of acne), and abscesses.
• 😀 Secondary UKK occurs due to the natural evolution of a disease or scratching, leading to conditions like scales (seen in psoriasis), crusts, lichenification (due to chronic friction or scratching), and atrophy.
• 😀 Common secondary UKK manifestations include excoriation (scratch-induced lesions) and fissures (caused by excessive skin stretching or reduced elasticity).

Q & A

What is the difference between primary and secondary skin lesions (UKK)?

Primary skin lesions (UKK) are direct changes in the skin caused by the main disease, whereas secondary skin lesions (UKK) are changes that occur due to the natural progression of the disease, such as scratching or infection.

What are the categories of primary skin lesions (UKK)?

Primary skin lesions are categorized into four main types: flat lesions, raised lesions, lesions with skin integrity damage, and other types that don't fit in the previous categories.

What is a macule and how is it different from a patch?

A macule is a flat lesion that is less than 1 cm in diameter, while a patch is similar but larger, measuring more than 1 cm in diameter. An example of a disease with macules and patches is vitiligo.

What are the three types of raised solid lesions, and how are they categorized?

The three types of raised solid lesions are: papules (less than 1 cm in diameter), nodules (more than 1 cm in diameter with a dome-like shape), and plaques (larger than 1 cm in diameter and thicker).

What is a vesicle, and which condition is commonly associated with it?

A vesicle is a fluid-filled lesion with a diameter of less than 1 cm. An example of a disease that presents with vesicles is herpes zoster.

What is the difference between erosion and ulceration in terms of skin lesions?

Erosion refers to skin damage that affects only the epidermis, while an ulcer (or ulceration) involves deeper damage, reaching the dermis.

What is urticaria, and how does it manifest on the skin?

Urticaria, also known as hives, is a skin condition that causes transient plaques due to edema in the dermis. These plaques usually last less than 24 hours.

What are keloids, and how do they form on the skin?

Keloids are hypertrophic scars that form when there is excessive fibrous tissue growth following a wound or injury. They result in raised, thick scars that are often larger than the original wound.

What is lichenification, and which conditions are associated with it?

Lichenification is the thickening of the skin with accentuated skin lines, usually due to chronic scratching or friction. It is commonly seen in chronic eczema or neurogenic conditions.

What causes a fissure in the skin, and where is it most commonly found?

A fissure is a crack in the skin caused by excessive stretching or loss of elasticity. It is commonly found in areas like the palms of the hands or soles of the feet, where the skin is thick.
