Number of Conditions: 5

Vitiligo

Specialty: Dermatology

Category: Skin Disorders

Sub-category: Pigmentation Disorders

Symptoms:
white patches on the skin; loss of pigmentation in hair, eyebrows, or eyelashes; typically symmetrical distribution

Root Cause:
Autoimmune destruction of melanocytes, leading to depigmented areas of skin.

How it's Diagnosed: videos
Clinical examination; Wood’s lamp examination to highlight depigmented areas.

Treatment:
Topical or systemic treatments to restore pigmentation or camouflage the skin.

Medications:
Topical corticosteroids (e.g., clobetasol ). Calcineurin inhibitors (e.g., tacrolimus ). Psoralen with UV-A therapy (PUVA).

Prevalence: How common the health condition is within a specific population.
Affects about 1% of the global population.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Family history, autoimmune diseases (e.g., thyroid disorders).

Prognosis: The expected outcome or course of the condition over time.
Chronic condition; treatment can stabilize or repigment skin in some cases.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Psychological distress; Sunburn on depigmented skin; Association with other autoimmune conditions

Hyperpigmentation (e.g., Melasma)

Specialty: Dermatology

Category: Skin Disorders

Sub-category: Pigmentation Disorders

Symptoms:
darkened patches of skin, typically on the face; irregular borders; symmetrical distribution; often exacerbated by sun exposure

Root Cause:
Overproduction of melanin by melanocytes, often triggered by sun exposure, hormonal changes, or medications.

How it's Diagnosed: videos
Clinical examination; Wood’s lamp examination to assess depth of pigmentation.

Treatment:
Topical depigmenting agents, sun protection, and chemical peels.

Medications:
Topical hydroquinone – for skin lightening. Retinoids (e.g., tretinoin ) – for skin renewal. Azelaic acid or kojic acid – alternative depigmenting agents.

Prevalence: How common the health condition is within a specific population.
Common, particularly in women and those with darker skin tones.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Pregnancy, hormonal therapies (e.g., oral contraceptives), sun exposure, family history.

Prognosis: The expected outcome or course of the condition over time.
Chronic condition; recurrences are common without sun protection.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Psychological distress; Persistent discoloration despite treatment

Albinism (Hypopigmentation)

Specialty: Dermatology

Category: Skin Disorders

Sub-category: Pigmentation Disorders

Symptoms:
complete or partial absence of melanin in skin, hair, and eyes; sensitivity to sunlight; vision abnormalities

Root Cause:
Genetic mutation affecting melanin production.

How it's Diagnosed: videos
Clinical examination, family history, genetic testing (for albinism).

Treatment:
Sun protection, camouflage makeup; no cure for albinism.

Medications:
Topical corticosteroids or calcineurin inhibitors – for post-inflammatory cases. Vitamin D supplements – for albinism due to reduced sun exposure.

Prevalence: How common the health condition is within a specific population.
1 in 17,000 to 20,000 people worldwide.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Genetic inheritance (albinism), history of skin inflammation or injury.

Prognosis: The expected outcome or course of the condition over time.
Lifelong condition; manageable with precautions.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Sunburn; Skin cancer; Vision problems

Post-Inflammatory Hypopigmentation

Specialty: Dermatology

Category: Skin Disorders

Sub-category: Pigmentation Disorders

Symptoms:
localized light patches of skin following inflammation or injury

Root Cause:
Loss of melanocytes or reduced melanin production following skin trauma.

How it's Diagnosed: videos
Clinical examination, family history, genetic testing (for albinism).

Treatment:
Sun protection, camouflage makeup; no cure for albinism.

Medications:
Topical corticosteroids or calcineurin inhibitors – for post-inflammatory cases. Vitamin D supplements – for albinism due to reduced sun exposure.

Prevalence: How common the health condition is within a specific population.
Common, especially after skin conditions like eczema or psoriasis.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Genetic inheritance (albinism), history of skin inflammation or injury.

Prognosis: The expected outcome or course of the condition over time.
Often resolves over time.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Psychological distress due to cosmetic appearance

Post-Inflammatory Hyperpigmentation

Specialty: Dermatology

Category: Skin Disorders

Sub-category: Pigmentation Disorders

Symptoms:
darkened patches of skin at sites of previous inflammation or injury; irregular borders; can affect any part of the body

Root Cause:
Overproduction of melanin in response to skin trauma, inflammation, or injury.

How it's Diagnosed: videos
Clinical examination; differentiate from other hyperpigmentation causes.

Treatment:
Topical depigmenting agents, chemical peels, and sun protection.

Medications:
Topical hydroquinone – for depigmentation. Retinoids (e.g., tretinoin ) – to improve skin renewal. Azelaic acid or kojic acid – alternatives for skin lightening.

Prevalence: How common the health condition is within a specific population.
Common, especially in individuals with darker skin tones.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Acne, eczema, psoriasis, or any condition causing skin inflammation.

Prognosis: The expected outcome or course of the condition over time.
Gradual resolution over months to years with treatment; recurrence possible if underlying cause persists.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Persistent discoloration; Psychological distress due to cosmetic concerns
