O eritema tóxico, também conhecido como reação exantemática, é um termo descritivo para uma erupção eritematosa aguda generalizada, geralmente simétrica, que pode ser desencadeada tanto por drogas quanto por infecções, mas que também pode ser o pródromo de uma ampla variedade de dermatoses. A causa precisa muitas vezes não pode ser identificada. Caracteriza-se por eritema sem alterações superficiais significativas, como escamas, exsudação ou ulceração. O eritema pode ser morbiliforme (como o sarampo), urticado (semelhante à urticária, mas não migratório) ou escarlatiniforme (confluente e macular semelhante à escarlatina). Uma pesquisa deve sempre ser feita para um gatilho subjacente. | |||

Toxic erythema, also known as an exanthematous reaction, is a descriptive term for an acute widespread usually symmetrical erythematous rash such as may be triggered both by drugs and by infections but which also may be the prodrome of a wide variety of dermatoses. The precise cause can often not be identified. It is characterised by erythema without significant surface changes such as scale, exudation or ulceration. The erythema may be morbilliform (like measles), urticated (resembling urticaria but not migratory) or scarlatiniform (confluent and macular resembling scarlet fever). A search should always be made for an underlying trigger. | |||
