Tinea manuum (or tinea manus [3]) is a fungal infection of the hand. [2] It is typically more aggressive than tinea pedis but similar in look. Itching, burning, cracking, and scaling are observable and may be transmitted sexually or otherwise, whether or not symptoms are present.
Onychomycosis, also known as tinea unguium, [4] is a fungal infection of the nail. [2] Symptoms may include white or yellow nail discoloration, thickening of the nail, and separation of the nail from the nail bed. [2] Fingernails may be affected, but it is more common for toenails. [3] Complications may include cellulitis of the lower leg. [3]
Tinea unguium: fungal infection of the fingernails and toenails, and the nail bed; Tinea corporis: fungal infection of the arms, legs, and trunk; Tinea cruris : fungal infection of the groin area; Tinea manuum: fungal infection of the hands and palm area; Tinea capitis: fungal infection of the scalp and hair
Onychomycosis, also known as tinea unguium, is a contagious infection of the nail caused by the same fungal organisms which cause ringworm of the skin (Trichophyton rubrum or T. mentagrophytes, rarely other trichophyton species or Epidermophyton floccosum [1]).
Tinea manuum is a fungal infection of the hand, mostly a type of dermatophytosis, often part of two feet-one hand syndrome. [ 2 ] [ 4 ] There is diffuse scaling on the palms or back of usually one hand and the palmer creases appear more prominent. [ 2 ]
Approximately 80–93% of chronic dermatophyte infections in many parts of the developed world are thought to be caused by T. rubrum, including cases of tinea pedis (foot), tinea unguium (nail), tinea manuum (hand), tinea cruris (groin), and tinea corporis (arms and leg), as well as some cases of tinea barbae (beard).

Children from ages 3–7 are most commonly infected with tinea capitis. [3] Trichophyton tonsurans is the most common cause of out breaks of tinea capitis in children, and is the main cause of endothrix (inside hair) infections. Trichophyton rubrum is also a very common cause of favus, a form of tinea capitis in which crusts are seen on the scalp.
[3] [6] Superficial fungal infections include common tinea of the skin, such as tinea of the body, groin, hands, feet and beard, and yeast infections such as pityriasis versicolor. [7] Subcutaneous types include eumycetoma and chromoblastomycosis, which generally affect tissues in and beneath the skin.
