What does a boiled lobster appearance indicate?

The appearance described as "boiled lobster" is associated with arsenic poisoning. This term refers to the characteristic reddening of the skin that can occur as a result of arsenic exposure, especially in cases of acute poisoning. Individuals may exhibit a flush or erythema, particularly on the palms, soles, and face, resembling the coloration of a boiled lobster.

Boric acid, mercury, and lead poisoning do not produce this specific dermatological symptom. While each of those toxic substances has its own set of clinical manifestations, they do not present with the distinctive "boiled lobster" appearance that is characteristic of arsenic poisoning. For instance, mercury poisoning often presents with neurological symptoms, and lead poisoning can cause a range of issues including abdominal pain and neurological deficits, but not the particular skin changes noted in arsenic cases.
