Introduction
Axillary osmidrosis (commonly known as “fox odor”) is a distinctive odor resulting from bacterial decomposition of sweat secreted by apocrine glands in the axillary region. It typically manifests before puberty and has a hereditary component. The condition is generally classified into mild, moderate, and severe forms. Mild cases are commonly managed with topical alum solution, frequent bathing, and regular changing of undergarments—measures that may alleviate symptoms but sometimes fail to prevent recurrence. For moderate-to-severe cases, surgical intervention is the only definitive treatment for axillary osmidrosis.

How Is Axillary Osmidrosis Treated?
For moderate-to-severe cases, surgical intervention is the only definitive treatment for axillary osmidrosis. Typically performed under local anesthesia, a minimally invasive subcutaneous excision via a small incision is used to completely remove the apocrine glands and hair follicles in the axillary region. Once these glands are fully excised, sweating ceases in the treated area, thereby eliminating the odor entirely.
Although various treatment modalities exist for axillary osmidrosis, surgery remains the most fundamental and effective approach. The underlying cause is abnormal secretion from the apocrine glands. In healthy individuals, two types of sweat glands coexist: eccrine and apocrine glands. Eccrine glands secrete primarily water and electrolytes, whereas apocrine glands produce organic compounds such as fatty acids and proteins. While these substances themselves are odorless, bacterial breakdown of them generates the characteristic pungent odor associated with axillary osmidrosis.
The most definitive treatment involves surgical removal of the hyperactive apocrine glands. However, because this is an invasive procedure, it is generally recommended only after skeletal maturity—i.e., once adulthood is reached. Since axillary osmidrosis often begins at puberty, surgery is not advised during adolescence. Instead, localized botulinum toxin injections may be administered—typically once annually, preferably between April and May.
Adults with severe symptoms should consider surgical treatment and are advised to seek care at a qualified medical facility. Additionally, maintaining local cleanliness and dryness—and thereby inhibiting bacterial proliferation—can also help mitigate symptoms.
