Keratolytic winter erythema

What it is

Keratolytic winter erythema is a rare epidermal disease, characterized by recurrent centrifugal palmoplantar peeling and erythema presenting seasonal variation (cold weather). Skin lesions may spread to the dorsum of hands and feet and to the interdigital spaces. Lower legs, knees and thighs may also be involved. Episodes may be preceded by itch and hyperhidrosis. Skin biopsy reveals an epidermal spongiosis with clefting in the stratum corneum, followed by regrowth. Keratolytic winter erythema follows an autosomal dominant mode of transmission.

Signs and symptoms

These ranges are how often a sign appears across everyone diagnosed, not a prediction for one person — most people have some of these and not others. Orphanet also records findings that are specifically absent in this disease; those are in the data but not listed here.

ICD-10 codes

ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
