How to treat axillary tinea

Axillary ringworm is more common in areas with more hair. It is caused by Corynebacterium slenderis and mostly occurs in the axillary hair or pubic hair. It appears in granular form. These granules are dense bacteria and are mostly yellow, black or red. The disease is more likely to recur in warm seasons, so special attention should be paid to the hygiene of the axillary hair and pubic hair. Clean them more often, change clothes more often, etc., so as to better prevent it.

Causes

The pathogen of this disease is Corynebacterium gracilis, which belongs to the genus Corynebacterium, is a type of diphtheroid bacteria, and is Gram-positive. These bacteria grow within and between cells of the hair epidermis and can invade the hair cortex but not the hair roots and skin.

Clinical manifestations

People who sweat excessively are prone to this disease. This disease only infects the axillary hair and pubic hair, mainly affecting the axillary hair, and the hair in other parts of the body is not easily invaded. The clinical manifestations are the appearance of yellow, black or red nodular particles on the hair shafts of axillary or pubic hair, with yellow being the most common color. These particles are almost all densely packed with bacteria. These nodules are either hard or soft, and wrap around the hair shaft in a sheath-like manner. They are tightly adhered to the hair shaft, causing it to lose its luster and become brittle, making it easy to break. The skin of the affected area appears normal and is often sweaty. Usually no symptoms. Depending on the color of the nodules, sweat can be yellow, black, or red. This disease often occurs in warm seasons.

diagnosis

The diagnosis is mainly based on clinical manifestations and pathogen examination. When you see yellow, black or red nodules or particles in your armpits, vulva, or on the shafts of your armpit hair or pubic hair, the first thing you should think of is this disease. Crush the nodule, add 10% potassium hydroxide solution, and examine under a high-power microscope. Short and slender rods can be seen, with hyphae embedded in sticky substances and Gram-positive staining.

Differential Diagnosis

This disease needs to be differentiated from pubic lice and trichomycosis.

treat

Pay attention to local hygiene and keep it clean and dry. Shave the affected armpit and pubic hair. Apply 5% sulfur cream or erythromycin cream topically; if local sweating occurs, 1% formalin solution can be given.
