Asteatotic eczema in hypoesthetic skin: a case series.

IMPORTANCE: Asteatotic eczema (eczema craquelé, xerotic eczema) occurs most frequently in areas of dehydrated skin, most often during the winter months when decreased humidity results in increased water loss from the stratum corneum. We present 5 cases in which asteatotic eczema was found outside of its normal distribution, within desensitized skin and scars.

OBSERVATIONS: Five patients with a history of trauma and scar formation presented with erythematous, dry plaques with fine crackling involving hypoesthetic skin. Each of the 5 patients had classic asteatotic eczema skin findings, the only commonality being hypoesthesia. Borders of the hypoesthetic skin were identified using light touch and compared with the regions affected by asteatotic eczema. In all cases, the skin affected by asteatotic eczema was within the hypoesthetic areas.

CONCLUSIONS AND RELEVANCE: Asteatotic eczema developing on skin with altered sensation is an underreported condition. Prompt recognition and treatment may lead to a more efficient patient encounter and alleviate unnecessary patient stress.
