​Dermatology - Tinea Manuum

​Dermatology - Tinea Manuum 
A particular class of fungus known as dermatiophytes is responsible for the infection of keratinized cutaneous tissues that causes tinea; arthrospores from these species can live for up to a year in skin scales.
The most prevalent ways for transmission are from person to person, from animals, and, less frequently, via soil. sometimes unilateral, tinea manuum occurs on the dominant hand and is sometimes confused with tinea pedis.

Tinea manuum often causes pruritus. It is possible for secondary infection to happen.
Lesions On the palmar hand, there are well-defined scaling patches, fissures, and hyperkeratosis; central clearing may also transpire. With dermatophytic folliculitis, the lesion may spread to the dorsum of the hand and manifest as pustules, nodules, and follicular papules. There is a dyshidrotic variety that has bullae, vesicles, and papules.

Fungal hyphae can be seen by direct microscopy of skin scrapings that have been taken using a no. 15 scalpel blade, the edge of a glass microscope slide, or a toothbrush (cervical or tooth brush) and covered with a drop of potassium hydroxide (KOH). Atopic dermatitis, lichen simplex chronicus, allergic contact dermatitis, irritant contact dermatitis, and psoriasis vulgaris are among the conditions on the differential.


Use imidazole powder, benzoyl peroxide wash, and dry skin to stop recurrences. If dermatophytic nail infection is present, make careful to treat it.

​Use allylamine lotion (naftifin, terbinafine), naphthionate ointment (tolnaftate), imidazole creams (clotrimazole, miconazole, ketoconazole, econazole, oxiconizole, sudonizole, sertaconazole), or substituted pyridine (ciclopirox olamine).
The most potent oral antidermophytic medication is Terbinafine, an allylamine, which is administered systemically as a 250 mg tablet for a period of 14 days. Fluconazole 150–200 mg tablets daily for two to four weeks or itraconazole 200 mg daily for seven days are two substitutes.
