Presents as an eczematous reaction in a pattern corresponding to contact with an allergen, rather than the burrows and generalized pruritus of scabies.
An 'id reaction' that is a secondary, widespread eczematous eruption resulting from a primary localized inflammatory process, like a stasis dermatitis or tinea.
An autoimmune blistering disease characterized by large, tense bullae on erythematous or urticarial bases, often in elderly patients.
Painful, violaceous nodules and plaques on acral sites (fingers, toes, ears) that are induced by exposure to cold, non-freezing temperatures.
Presents as intensely pruritic, grouped vesicles and papules on extensor surfaces (elbows, knees, buttocks), strongly associated with celiac disease.
Characterized by well-demarcated, coin-shaped, weeping, or crusted plaques, unlike the diffuse papules and burrows of scabies.
A general term for inflammation, but typically lacks the characteristic burrows, intense nocturnal pruritus, and history of affected contacts seen in scabies.
Presents as pustules centered around hair follicles, which is not a primary feature of scabies, although secondary infection can occur.
Usually presents as discrete, grouped urticarial papules at the site of the bites, rather than the widespread papules and burrows of a scabies infestation.
Identified by its purple, polygonal, pruritic papules, often with Wickham's striae, a distinct morphology from scabies.
Characterized by intensely itchy, firm, excoriated nodules that arise from chronic scratching, but lacks the primary burrows of scabies.
Infestation is confined to areas with terminal hair (pubis, axilla, eyelashes), and nits can be seen attached to hair shafts.
