136. Tinea Manuum


Tinea infections

"Tinea" refers to a skin infection with a dermatophyte (ringworm) fungus.

Depending on which part of the body is affected, it is given a specific name :

Sometimes, the name gives a different meaning :

  • Tinea versicolor is more accurately called pityriasis versicolor. This is a common yeast infection on the trunk.

  • Tinea incognita (often spelled incognito) refers to a tinea infection in which the clinical appearance has changed because of inappropriate treatment.

  • Tinea nigra is a mould infection (not a dermatophyte). It affects the palms or soles, which appear brown (on white skin) or black (on dark skin).

Clinical variants include :

  • Tinea imbricata

  • Majocchi granuloma

  • Kerion

  • Favus


What is tinea manuum ?

Tinea manuum is the name given to infection of one or both hands with a dermatophyte infection.


It is much less common than tinea pedis (tinea affecting the foot).

Tinea manuum is frequently misdiagnosed because it appears similar to:

  • Hand dermatitis - especially the type called pompholyx.

  • Psoriasis - especially palmoplantar pustulosis.

  • Keratolysis exfoliativa.

Clinical features of tinea manuum

Tinea manuum can occur as an acute inflammatory rash like tinea corporis.

There is usually a raised border and clearing in the middle (ringworm).

This is most likely when a zoophilic (animal) or geophilic (soil) fungus is responsible.


The likely fungi are:

  • Trichophyton erinacei - from a hedgehog

  • T. verrucosum - from cattle

  • Microsporum canis - from a cat or dog

  • M. gypseum - from soil


More frequently, tinea manuum causes a slowly extending area of peeling, dryness and mild itching on the palm of one hand (hyperkeratotic tinea).

Skin markings may be increased.

Generally both feet appear similar ("one hand, two foot syndrome").


The usual cause is an anthropophilic (human) fungus:

  • T. rubrum

  • T. mentagrophytes var. interdigitale

  • Epidermophyton floccosum


These fungi may also cause a blistering rash on the edges of the fingers or palm.

The blisters appear in crops and contain a sticky clear fluid. They may have a peeling edge.

This form of tinea manuum itches and burns.


Predisposing factors for tinea manuum


Tinea manuum results from:

  • Contact with another site of infection, particularly the feet (tinea pedis) or groin (tinea cruris)

  • Contact with another person with tinea

  • Direct contact with an infected animal or soil

  • Contact with a contaminated object such as a towel or gardening tool


It is more likely in those doing manual work, who sweat profusely (hyperhidrosis) or who already have hand dermatitis.


Distinguishing features of tinea manuum


Tinea manuum can be distinguished from hand dermatitis:

  • In most cases of tinea manuum, only a single hand is involved.

  • If both hands are affected, involvement is asymmetrical.

  • Increased skin markings can be seen in dermatitis but in chronic tinea manuum they are white because of surface scale.

  • Involvement of both palm and back of hand in contiguity.

  • The rash may have an elevated border.

  • Nearby nails may also be infected (tinea unguium). However, other skin conditions can also affect nails.


Diagnosis of tinea manuum


The diagnosis of tinea manuum is confirmed by microscopy and culture of skin scrapings.


Treatment of tinea manuum

Mild tinea manuum is treated with topical antifungal agents, but if the treatment is unsuccessful, oral antifungal medicines may be considered, including terbinafine and itraconazole.
