[Lymphocutaneous sporotrichosis in a pediatric patient, a case report].

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.
