Dermatophytosis

Dermatophytosis, commonly known as tinea or ringworm, is a superficial fungal infection affecting keratinized tissues of the integumentary system, including the stratum corneum of the epidermis, hair, and nails It occurs across diverse patient populations and is primarily caused by filamentous fungi belonging to the genera *Trichophyton*, *Microsporum*, and *Epidermophyton* Clinical manifestations typically include pruritic, well-demarcated, annular, erythematous plaques with raised, active, sca...

Dermatophytosis, commonly known as tinea or ringworm, is a superficial fungal infection affecting keratinized tissues of the integumentary system, including the stratum corneum of the epidermis, hair, and nails It occurs across diverse patient populations and is primarily caused by filamentous fungi belonging to the genera *Trichophyton*, *Microsporum*, and *Epidermophyton* Pathophysiologically, these organisms secrete keratinases and other enzymes to degrade and colonize keratin

Pathophysiologically, these organisms secrete keratinases and other enzymes to degrade and colonize keratin Pathophysiologically, these organisms secrete keratinases and other enzymes to degrade and colonize keratin, provoking a local host inflammatory response

Clinical manifestations typically include pruritic, well-demarcated, annular, erythematous plaques with raised, active, scaly borders and central clearing on the skin, as well as alopecia, hair shaft fragility, or thickened, discolored, and dystrophic nail plates when appendages are involved
