The sudoriferous gland disorder that causes foul-smelling perspiration:

• A. Hyperhidrosis
• B. Bromhidrosis
• C. Anhidrosis
• D. Miliaria rubra

Answer: (B)

Foul-smelling sweat comes from the activity of apocrine glands, whose thicker secretions are broken down by skin bacteria, releasing odor. This combination creates bromhidrosis. It’s different from simply sweating more (hyperhidrosis), which is excess sweat without necessarily strong odor; from not sweating at all (anhidrosis); and from a heat rash like miliaria rubra, which is a blocked-sweat-duct condition with red, itchy bumps rather than odor. In skincare contexts, bromhidrosis is tied to odor management: good hygiene, breathable fabrics, and sometimes targeted antiperspirants or antibacterials, with medical evaluation if odor is persistent or severe.
