Which condition results in a foul odor from perspiration?

1. Hyperhidrosis

2. Bromhidrosis

3. Acanthosis

4. Seborrheic dermatitis

The correct answer is: Bromhidrosis

Bromhidrosis is the condition responsible for the foul odor that can result from perspiration. This odor is produced when sweat interacts with bacteria on the skin. While sweat itself is generally odorless, bromhidrosis occurs when bacteria break down the proteins and fatty acids found in the perspiration, leading to the production of strong-smelling compounds. On the other hand, hyperhidrosis refers to excessive sweating, which may not necessarily produce a foul smell. Acanthosis is a skin condition characterized by dark, velvety patches and is not related to perspiration odor. Seborrheic dermatitis is a skin disorder that leads to oily, scaly patches and irritation, but it does not typically cause a foul odor associated with sweating. Thus, bromhidrosis is specifically linked to the undesirable scent that can accompany sweating due to bacterial action on sweat components.
