Mycosis of the hands

Mycosis of the hands (mycosis manus) is a skin lesion of the hands caused by some dermatophyte fungi, which has a common localization and similar clinical manifestations.

Cause and pathogenesis of mycosis of the hands

The most common pathogens of hand mycosis are red trichophyton (Trichophyton rubmm), interdigital trichophyton (Trichophyton mentcigrophytes, var. interdigitale), and less commonly, other dermatophytes.

A significant role is played by finger trauma and disruption of the microcirculation in the distal parts of the upper extremities (atherosclerosis, Raynaud's syndrome), as well as endocrine disorders and immunosuppressive conditions.

Symptoms and diagnosis of mycosis of the hands

Clinically, the palmar lesions are similar to the manifestations of the squamous-hyperkeratotic form of mycosis of the feet. The lesion may be symmetrical. Dry skin of the palms, thickening of the stratum corneum (keratosis), mucous peeling in exaggerated skin grooves and ring-shaped peeling are characteristic. Lesions may also be observed on the hands in the form of areas of cyanotic erythema with scalloped or oval outlines. The edges of the lesions are discontinuous and consist of nodules, vesicles and crusts. Lesions of the palms may be combined with onychomycosis of the hands.

Diagnosis of mycosis of the hands is similar to diagnosis of mycosis of the feet.

Differential diagnostics

Mycosis of the palms and soles caused by Trichophyton rubra must be differentiated from psoriasis, chronic eczema and keratoderma of this localization.

Treatment and prevention of mycosis of the hands

Treatment is similar to that of mycosis of the feet.
