“…Tinea incognito, which is an exacerbated manifestation of dermatophytosis, may present differently from regular tinea. Its pathogenesis is explained by the altered-by-steroids response of the host to cutaneous fungal infection [ 10 ]. Based on a literature review, the most common causative factor of tinea incognito seems to be Trichophyton rubrum , followed by Trichophyton mentagrophytes and Epidermophyton floccosum [ 11 , 12 , 13 ], whereas the most common location seems to be the limbs [ 11 ] or trunk [ 13 ].…”

Tinea incognito is a dermatophyte infection exacerbated after inadequate administration of topical or systemic glucocorticoids. A 57-year-old man presented to the Department of Dermatology due to skin lesions persisting for one month. He reported having recently worked under hot conditions, in tight clothing, which caused sweating. Later, he noticed erythematous–exfoliative lesions in his groins and on the buttocks. He presented to the general practitioner who diagnosed him with eczema and prescribed clobetasole ointment. Since the skin lesions became more severe, he presented to the Department of Dermatology. On the physical examination, extensive erythematous–infiltrative lesions were observed in the area of medial, lateral, and posterior surface of both thighs and buttocks. Pustules were also present. Suspicion of tinea incognito was raised, and direct mycological examination and culture confirmed the presence of dermatophytes. The patient was prescribed topical terbinafine and oral itraconazole. Tinea incognito may be challenging to diagnose because the clinical presentation is relatively nonspecific and definitive culture or histopathological diagnosis such as by microscopic sample examination to identify fungal elements is not universally available. Every doctor has to keep in mind the fact that tinea may be a great mimicker of other dermatoses and to not prescribe medications without microscopic confirmation of tinea, and refer patients for dermatological consultation in case of doubt.

ANTECEDENTES: La tiña incógnita es una infección dermatofítica, con una morfología modificada debido al uso inapropiado de esteroides tópicos, sistémicos o inhibidores de la calcineurina. Este problema es más frecuente en casos de tiñas faciales y constituye un reto diagnóstico que requiere historia clínica minuciosa, examen físico y estudios complementarios. En países tropicales, en vías de desarrollo, las dermatofitosis son un problema de gran prevalencia debido a múltiples factores: clima cálido, hacinamiento, contacto con animales y malos hábitos de higiene. Honduras no es la excepción y, además de los factores mencionados, la venta de medicamentos sin prescripción favorece la automedicación. Otro factor contribuyente es la no disponibilidad de exámenes de laboratorio en la mayor parte de los centros asistenciales estatales, lo que dificulta la confirmación diagnóstica de una dermatosis.CASOS CLÍNICOS: Se comunican dos casos de tiña facial incógnita en dos pacientes del sexo femenino en edad pediátrica ocasionadas por Trichophyton verrucosum y tratadas con la combinación de antimicóticos tópicos y sistémicos con excelentes resultados.CONCLUSIÓN: Es imporante concientizar a los profesionales de la salud acerca del riesgo del uso inapropiado de esteroides y de inhibidores de la calcineurina en dermatosis eritematoescamosas, sobre todo las faciales.

“…The pathogenesis of TI is distinct from traditional tinea infections because it is altered by the use of topical steroid creams, systemic corticosteroids, or other immunosuppressive medications. [48]. These medications, particularly when used frequently or in high doses, can weaken the normal immune responses of the skin and reduce the inflammation that fights against fungal infections.…”

Tinea incognito is a kind of skin infection that is caused by a fungus which has been changed by the use of topical or systemic steroids or other immunosuppressive medications. This alteration in the typical clinical presentation of the infection makes it difficult to diagnose for general practitioners and dermatologists. Delayed diagnosis, spread of the infection to critical body surfaces, resistance to antifungal drugs, and increased costs due to prolonged hospitalization and multiple treatment regimens often complicate tinea incognito. This condition can affect individuals of all ages and genders, but it is more common in children. Tinea incognito is a type of fungal skin infection that can present with various and non-specific clinical features, such as sudden onset of itching in an area that was previously unaffected, making it challenging to differentiate from other diseases such as eczema, seborrheic dermatitis, lupus erythematosus, psoriasis, or other non-fungal skin conditions. The treatment of tinea incognito usually involves stopping the use of topical steroids or other immunosuppressive medications. Preventive measures and management of the underlying fungal infection are necessary and can be achieved with antifungal drugs. Patients should wear loose cotton clothes, use boiling water for laundry, and iron their clothing before wearing them. Additionally, they should avoid sharing bed linens, towels, clothes, and shoes. This review aims to raise awareness of tinea incognito among health practitioners, provide tips for suspecting the disorder, include it in the differentials, and evaluate the available diagnostic procedures. The therapy utilized in published studies is also reviewed.
