Tinea manuum

Tinea manuum is a superficial dermatophyte infection of the integumentary system that involves the palmar surfaces, interdigital folds, or dorsal aspects of one or both hands Clinically, it typically presents with asymmetric, chronic hyperkeratosis, fine scaling accentuated in the palmar creases, and variable pruritus, or as annular erythematous plaques with elevated active borders on the dorsum of the hand

Tinea manuum is a superficial dermatophyte infection of the integumentary system that involves the palmar surfaces, interdigital folds, or dorsal aspects of one or both hands Most frequently caused by anthropophilic species such as *Trichophyton rubrum*, the fungal pathogen invades the keratinized stratum corneum, often following direct contact, animal exposure, or autoinoculation from preexisting tinea pedis or onychomycosis Clinically, it typically presents with asymmetric, chronic hyperkerato...

Clinically, it typically presents with asymmetric, chronic hyperkeratosis, fine scaling accentuated in the palmar creases, and variable pruritus, or as annular erythematous plaques with elevated active borders on the dorsum of the hand It frequently manifests as part of the classic "two feet, one hand" syndrome, where bilateral pedal dermatophytosis coexists with unilateral hand involvement
