Tinea pedis, commonly known as athlete’s foot, is a contagious fungal infection affecting the skin of the feet. It thrives in warm, moist environments, making damp communal areas like locker rooms and swimming pools breeding grounds. This condition is caused by various fungi, with Trichophyton species being the most common pathogen. Characterized by (but not always) itching, burning sensations, and peeling skin, athlete’s foot often manifests between the toes and the arch of the foot. While generally not serious, untreated cases, especially amongst diabetics, can lead to complications and spread to other parts of the body. Maintaining good foot hygiene, control of sweating, wearing breathable footwear, and using antifungal medications are essential for prevention and treatment.

Fungal nails, medically known as onychomycosis, represent a common and stubborn fungal infection affecting the toenails or fingernails. This condition typically begins as a white or yellow spot under the nail, gradually spreading and causing thickening, discoloration, and distortion of the nail. Dermatophyte fungi, as well as yeast and molds, can contribute to this ailment, thriving in warm, moist environments. Fungal nails are more prevalent in toenails due to limited light exposure and increased humidity in shoes. While not usually painful, severe cases may lead to discomfort and difficulty walking. Treatment involves antifungal medications, topical or oral, coupled with proper nail care to promote healing and prevent recurrence.

Green nail syndrome is a bacterial infection that often occurs beneath artificial nails or in traumatized natural nails. Pseudomonas aeruginosa is the common culprit, causing a greenish discoloration. Treatment involves proper nail care, removal of artificial nails, acetic acid and, if necessary, topical or oral antibiotics.

Erythrasma is a bacterial skin infection that particularly affects the interdigital spaces of the foot (between the toes). Caused by Corynebacterium Minutissimum, it has a characteristic smell and manifests as reddish-brown patches seen under ultraviolet light. Good hygiene and topical antibiotics are effective treatments, emphasizing the importance of recognizing and addressing this common and curable condition.

Pitted keratolysis is a bacterial skin infection primarily affecting the soles of the feet. Caused by Corynebacterium and Dermatophilus species, it leads to shallow pits, malodor, and white, easily removable scales. Proper foot hygiene, antibacterial soaps, and topical antibiotics are key in managing and preventing this treatable condition.
