How does Trichophyton Rubrum change the color of nail and skin?

Trichophyton rubrum is a fungus that can cause skin and nail infections, commonly known as ringworm or athlete's foot. The discoloration of nails and skin associated with T. rubrum infection is primarily due to the inflammatory response triggered by the fungal invasion. Here's how T. rubrum affects the color of nails and skin:

Nails:

- Discoloration: T. rubrum infection can cause nails to become discolored, ranging from white or yellow to brown or even black. The discoloration may appear as spots, streaks, or patches on the nail plate.

- Thickening: Infected nails often become thickened and crumbly due to the accumulation of fungal debris and increased keratin production. This thickening can further alter the nail's color, making it appear opaque or dull.

- Separation (Onycholysis): In some cases, T. rubrum infection can lead to the separation of the nail from the nail bed. This condition, known as onycholysis, can cause the nail to appear lifted or detached, exposing the nail bed beneath. The exposed nail bed may appear red, inflamed, and discolored.

Skin:

- Redness: T. rubrum infections on the skin typically cause redness and inflammation. The affected area may appear reddish or pinkish and feel warm to the touch.

- Scaling: The skin may develop scaly or flaky patches due to the fungal infection. The scales can vary in color from white or silver to brown or red, depending on the individual's skin tone and the severity of the infection.

- Circular lesions: Ringworm, a common T. rubrum infection, often manifests as circular or oval lesions on the skin. These lesions may have a raised, red border with a clearer center. The color of the center can vary, ranging from normal skin color to shades of pink or brown.

It's important to note that the exact color changes associated with T. rubrum infections can vary from person to person and depend on factors such as skin tone, the extent of the infection, and individual immune response. If you experience any persistent skin or nail discoloration, it is advisable to consult a dermatologist for proper diagnosis and treatment.
