Eczema is a chronic inflammatory skin condition marked by dry skin patches prone to itching and irritation. Atopic dermatitis primarily affects children but may continue into adulthood or develop later in life.

• Pathophysiology: Genetic predisposition leads to barrier dysfunction making skin susceptible to irritants and allergens triggering inflammation.
• Diagnosis: Clinical evaluation focuses on characteristic morphology including lichenification and distribution typical for age groups along with patient history.
• Treatment approach: Emollients restore barrier function alongside anti-inflammatory therapies such as topical corticosteroids or calcineurin inhibitors during flares.
• Prevention strategies: Avoidance of known irritants/allergens plus maintaining adequate hydration supports long-term management goals reducing exacerbations frequency.

Understanding triggers along with consistent skincare forms the cornerstone of controlling atopic dermatitis symptoms providing improved comfort and quality of life.

The use of dermatoscopy enhances the evaluation of pigmented skin lesions beyond visual inspection. This non-invasive technique aids in differentiating benign moles from malignancies such as melanoma.

• Pigmentation patterns: Dermatoscopy reveals structures like pigment networks and globules not visible to the naked eye.
• Indications: Applied when there are atypical features or patient risk factors warrant closer examination.
• Differential diagnosis assistance: Helps identify benign conditions such as seborrheic keratoses versus suspicious nevi requiring biopsy.
• User expertise requirement: Interpretation demands specialized training for accurate clinical decisions based on observed patterns.

This tool improves diagnostic accuracy while reducing unnecessary invasive procedures for patients presenting with pigmented lesions.

Early detection of melanoma significantly improves prognosis. Melanoma screening focuses on identifying suspicious moles or lesions that may indicate skin cancer.

• Risk factors: Include fair skin, history of sunburns, family history of melanoma, and numerous moles.
• Screening process: Visual examination using dermoscopy to assess asymmetry, border irregularity, color variation, diameter, and evolving features (ABCDE criteria).
• Diagnostic confirmation: A biopsy may be performed on suspicious lesions to confirm melanoma.
• Follow-up care: Regular skin checks help detect new or changing lesions early.

This proactive approach allows timely intervention to reduce morbidity associated with melanoma.
