The KOH test is a simple, rapid diagnostic method used to differentiate fungal infections from other skin conditions by dissolving keratin and revealing fungal elements under a microscope. It is particularly useful in dermatology for diagnosing superficial fungal infections such as dermatophytosis and candidiasis.

Diagnostic method

Fungal infections, also known as mycoses, are caused by a variety of fungi and can affect the skin, nails, or internal organs, ranging from mild to life-threatening conditions. Treatment often involves antifungal medications, but resistance and recurrence are challenges, making early diagnosis and prevention crucial.

Fungal Infections

Skin conditions encompass a wide range of disorders affecting the skin, which can vary in symptoms, severity, and treatment. Understanding these conditions involves recognizing their underlying causes, such as genetics, environmental factors, and immune system responses, to provide effective management and care.

A microscope is an optical instrument that magnifies small objects or details of larger objects, allowing for detailed observation and analysis that is not possible with the naked eye. It is crucial in fields like biology, materials science, and nanotechnology for studying structures at micro and nano scales.

Dermatology is the branch of medicine that focuses on the diagnosis, treatment, and prevention of skin, hair, and nail disorders. It encompasses a wide range of conditions, from acne and psoriasis to skin cancer and cosmetic concerns, requiring both clinical and surgical expertise.

Superficial fungal infections

Dermatophytosis, commonly known as ringworm, is a contagious fungal infection affecting the skin, hair, and nails, caused by dermatophyte fungi. It is characterized by red, scaly patches that may be itchy, and is typically treated with antifungal medications.

Dermatophytosis

Candidiasis is a fungal infection caused by Candida species, commonly Candida albicans, affecting various parts of the body including the mouth, throat, and genitals. It can result from an imbalance in normal flora due to factors like antibiotic use, weakened immune system, or diabetes, requiring antifungal treatment for resolution.
