Trichobacteriosis axillaris

Trichobacteriosis axillaris is a superficial bacterial colonization of the hair shafts in sweat gland–bearing areas, such as the armpits and the pubic region. It is a relatively common condition, but often goes undiagnosed. The condition is characterized by the presence of smelly, sticky, yellowish concretions on the hair shafts.

Causes

Trichobacteriosis axillaris is caused by the overgrowth of Corynebacterium, a type of bacteria that is normally found on the skin. The bacteria proliferate in a warm, moist environment and produce substances that cause the characteristic symptoms of the condition. Factors that can contribute to the development of trichobacteriosis axillaris include poor hygiene, excessive sweating, and the use of tight, non-breathable clothing.

Symptoms

The main symptom of trichobacteriosis axillaris is the presence of smelly, sticky, yellowish concretions on the hair shafts. These concretions can be easily removed by scraping. Other symptoms may include itching and a slight burning sensation.

Diagnosis

The diagnosis of trichobacteriosis axillaris is usually made based on the characteristic clinical features. A skin scraping may be taken for microscopic examination to confirm the diagnosis.

Treatment

The treatment of trichobacteriosis axillaris involves improving hygiene, using antiperspirants, and shaving the affected areas. In severe cases, antibiotics may be prescribed.

Prevention

Prevention of trichobacteriosis axillaris involves maintaining good personal hygiene, using antiperspirants, and wearing loose, breathable clothing.
