Acne vulgaris is a chronic inflammatory disorder of the pilosebaceous unit presenting with comedones, papules, pustules or nodules, commonly affecting the face, chest and back. Early severity assessment and stepwise management—using appropriate topical agents, systemic therapy when indicated and timely referral for severe cases—are key to preventing scarring and reducing psychosocial impact.
Cellulitis and erysipelas are acute bacterial infections of the skin and subcutaneous tissues, presenting with erythema, warmth, swelling and pain, often accompanied by systemic features. Erysipelas typically involves the superficial dermis with well-demarcated borders, whereas cellulitis affects deeper tissues with less distinct margins. Prompt clinical recognition, assessment of severity and early initiation of appropriate antibiotics—alongside identification of portals of entry and risk factors—are essential to prevent complications and recurrence.
Atopic eczema is a chronic inflammatory skin disorder marked by intense pruritus, dryness, and eczematous lesions. It commonly affects flexural areas and can significantly impact quality of life. Management focuses on regular emollient use, topical anti-inflammatory treatments, trigger avoidance, and education to reduce flares and maintain skin barrier function.
Onychomycosis refers to fungal infection of the nail unit, leading to discolouration, thickening and nail dystrophy. Diagnosis should be confirmed where possible, with treatment tailored to disease extent using topical or systemic antifungals to improve cure rates and limit relapse.
Scabies is a contagious skin infestation caused by Sarcoptes scabiei, presenting with intense nocturnal itching, papular rashes, and burrows, often in web spaces and flexural areas.
Diagnosis is clinical, supported by microscopy when needed.
Treatment involves topical or oral anti-parasitic therapy, environmental decontamination, and management of close contacts to prevent reinfestation.
