Summary

[edit]
Description
English: Very high magnification micrograph of confluent epidermal necrosis. Skin biopsy. H&E stain.

Confluent epidermal necrosis is seen in the context of erythema multiforme (EM), Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN).

SJS and TEN are generally considered to be on a spectrum and usually due to medications. EM is histomorphologically indistinguishable from SJS/TEN. It is usually due to an infection.

Histomorphologic features:

  1. A basket weave-type stratum corneum (indicative of the acuity).
  2. Epidermal necrosis.
  3. Separation of the epidermis and dermis.
  4. Minimal inflammation.
