Description:Under a magnification of 200X, this photomicrograph revealed some of the ultrastructural pathologic changes that were exhibited by a hair shaft affected by an endothrix infection caused by the dermatophytic fungus, Trichophyton tonsurans. This specimen had been mounted using potassium hydroxide (KOH).
Dermatophyte infections can affect the skin on almost any area of the body, such as the scalp, legs, arms, feet groin, and nails. These infections are usually itchy. Redness, scaling, cracking of the skin, or a ring-shaped rash may occur. If the infection involves the scalp or beard, hair may fall out. Infected nails become discolored, thick, and may possibly crumble. More serious infections may lead to an abscess or cellulitis.
