Sporotrichosis is a subacute-chronic fungal infection caused by dimorphic fungi of the Sporothrix schenckii Complex. It is more common in tropical areas. The prevalence in Argentina is estimated between 0.01 and 0.02%. In half of the patients it manifests as lymphocutaneous sporotrichosis, which occurs after inoculation of the fungus into the skin after minor trauma. The initial lesion is a papule or nodule that occurs with the appearance of an ascending chain of mobile, painless and erythematous subcutaneous nodules. The diagnosis is made from mycological culture. The antifungal of choice is itraconazole and the prognosis is usually favorable. We present the case of a healthy 4-year-old girl who consulted for subacute axillary lymphadenopathy without response to multiple antimicrobial regimens, arriving at the diagnosis of lymphocutaneous sporotrichosis from the culture of a lymph node biopsy sample.

Resumen La esporotricosis es una infección fúngica de evolución subagudacrónica causada por hongos dimórficos del Complejo Sporothrix schenckii. Es más frecuente en zonas tropicales. La prevalencia en Argentina se estima entre 0,01 y 0,02%. En la mitad de los pacientes se manifiesta como una esporotricosis linfocutánea, la cual se produce tras la inoculación del hongo en la piel luego de un trauma menor. La lesión inicial es una pápula o nódulo que se sucede con la aparición de una cadena ascendente de nódulos subcutáneos móviles, indoloros y eritematosos. El diagnóstico se realiza a partir del cultivo micológico. El antifúngico de elección es itraconazol y el pronóstico es usualmente favorable. Se presenta el caso de una niña de 4 años, previamente sana, que consultó por adenopatías axilares de evolución subaguda sin respuesta a múltiples esquemas antimicrobianos, confirmándose el diagnóstico de una esporotricosis linfocutánea por el cultivo de una biopsia ganglionar.
