Mycosis of large folds

Mycosis of large folds - lesions of the skin of the folds and adjacent areas caused by Trichophyton rubrum, Epidermophyton floccosum (seu inguinale), and Trichophyton mentagrophytes.

Pathogenesis of mycosis of large folds

Mycosis of large (pahovobedrennye and interannual folds and skin under the mammary glands, folds of the abdomen, etc.) folds most often develops as a result of predisposing exogenous factors that favor the introduction and spread of the fungus. The main exogenous factors are maceration and friction that occur in fat people and when wearing a tight, synthetic, not seasonally warm clothing, predisposes to excessive sweating. Endogenous factors for the development of lesion lesions are the same as for common mycosis of smooth skin. Mycosis of the folds often develops when there is focal fungal infection on the feet. With mycosis, the pathogenic fungus can enter the skin of the inguinal folds exogenously, less often lymphogenically or hematogenously. The disease usually recurs in the spring or autumn, it is widespread in countries with a humid, hot climate.

Symptoms of mycosis of large folds

Mycosis of the inguinal folds, caused by the red trichophyton, is characterized by polymorphous rashes on the skin, itching of varying intensity and chronic course. The disease manifests itself in red, scaly, round or oval foci, with a penchant for peripheral growth, fusion, polycyclic outlines and edematous, cherry red color, a discontinuous roller consisting of follicular papules, individual pustules and vesicles. The skin within the inguinal fold is weakly infiltrated, in its depth maceration and surface cracks are possible. Over time, the focus in the middle part acquires a 6-color shade and gradually extends beyond the fold. Manifestations of the disease are also bilateral, but they are located in the folds and on the 6dpax usually asymmetric.

Similar clinical manifestations occur in the inguinal and femoral folds of inguinal epidermophyte. This mycosis mainly affects the skin of the inguinal folds, rarely - the nail plates, and is characterized by a chronically recurrent course. Infection occurs when you are in contact with a sick person, as well as through the toilet articles used by the patient (scouring pads, ships, linens).

Differential diagnosis of mycosis of large folds

Defeat of large folds by dermatophytes must be differentiated from erythrasma, psoriasis of folds, seborrheic dermatitis, streptococcal and candidal intertrigo.

Treatment of mycosis of large folds

External therapy with preparations with antifungal activity and a wide spectrum of action, such as azoles, allylamines, cyclopyrox and amorolfine derivatives is recommended. An adequate effect on the pathogenetic background of the disease is important.
