Axillary odor, also known as fox odor, is a special odor produced by the armpits, which is especially noticeable when it is hot and sweaty. The reason for this is the presence of gram-positive bacteria in the sweat glands of the patient, which decompose the excreted sweat and produce the odor, causing adverse physical and psychological effects to the patient. The best treatment for axillary odor is surgery. For example, axillary skin excision and minimally invasive sweat gland removal. The most recommended procedure is minimally invasive sweat gland removal, which can selectively remove sweat glands with small incisions, little damage and inconspicuous scarring.
