Dermatitis and Rashes conditions
AcneAcne is a common inflammatory skin condition caused by clogged hair follicles and excess sebum, leading to comedones, papules, pustules, and sometimes cysts.Allergic contact dermatitisAllergic contact dermatitis is a delayed hypersensitivity reaction causing itchy, erythematous skin after exposure to specific allergens like nickel or poison ivy.Atopic dermatitis (eczema)Atopic dermatitis (eczema) is a chronic inflammatory skin condition marked by pruritus and dry, scaly patches linked to filaggrin gene mutations and barrier dysfunction.Erythema multiformeErythema multiforme is an acute hypersensitivity reaction often triggered by infections like HSV, characterized by target lesions and mucosal involvement.Erythema nodosumErythema nodosum is an inflammatory condition causing tender red nodules, usually on the shins, often linked to infections, medications, or systemic diseases.Lichen PlanusLichen Planus is a chronic inflammatory condition characterized by pruritic, purple, polygonal papules often linked to T-cell mediated autoimmune response.Pityriasis roseaPityriasis rosea is a self-limiting skin rash characterized by a herald patch followed by a widespread scaly eruption, often linked to viral infections.Pseudofolliculitis barbaePseudofolliculitis barbae is a chronic inflammatory skin condition caused by ingrown hairs after shaving, leading to papules, pustules, and irritation in the beard area.PsoriasisPsoriasis is a chronic autoimmune skin disorder characterized by hyperproliferation of keratinocytes and silvery scaly plaques, often linked to HLA-Cw6.Radiation dermatitisRadiation dermatitis is skin inflammation caused by ionizing radiation, characterized by erythema and desquamation, commonly seen in cancer radiotherapy patients.RosaceaRosacea is a chronic inflammatory skin condition causing facial redness, visible blood vessels, and sometimes acne-like bumps, often triggered by sun exposure or heat.Seborrheic dermatitisSeborrheic dermatitis is a chronic inflammatory skin disorder linked to Malassezia yeast overgrowth, causing flaky, scaly patches on oily areas like the scalp.Stevens-Johnson syndrome (SJS)Stevens-Johnson syndrome (SJS) is a severe mucocutaneous reaction often triggered by medications, characterized by epidermal necrosis and detachment.Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis (SJS/TEN) Overlap SyndromeSJS/TEN overlap syndrome is a severe mucocutaneous reaction causing widespread epidermal necrosis and detachment, often triggered by medications.Toxic Epidermal Necrolysis (TEN)Toxic Epidermal Necrolysis (TEN) is a severe mucocutaneous reaction causing widespread epidermal detachment, often triggered by medications and linked to high mortality.UrticariaUrticaria is characterized by transient, pruritic wheals caused by histamine release from mast cells, often triggered by allergens or physical stimuli.
