Appears as a glazed, erythematous, fissured eruption on the weight-bearing surfaces of the feet in children, sparing the instep, unlike the diffuse scaling of psoriasis.
Presents as crusted, waxy, hyperkeratotic papules and plaques on the soles, strongly associated with reactive arthritis.
Characterized by shallow pits on the plantar surface, often accompanied by a foul odor, and is caused by a bacterial, not an inflammatory, process.
