Nasal Sporotrichosis in Children

The document reports on three cases of nasal sporotrichosis, a chronic fungal infection caused by the Sporothrix schenckii species complex, in children. The first case involved a 12-month-old girl with papules and crust on her nose, the second case was a 5-year-old boy with scaly papules and an abscess, and the third case was a 3-year-old girl with papules and plaque. All three cases were diagnosed based on clinical findings, culture, and a positive intradermal sporotrichin test. The children were treated with a 10% solution of potassium iodide and, in one case, combined with itraconazole. The lesions resolved after three to four months of treatment. The patients lived in an endemic area for sporotrichosis, had no contact with cats, and other potential diagnoses such as atypical mycobacterial infections, cutaneous tuberculosis, and cutaneous leishmaniasis were ruled out. The cultures grew Sporothrix schenckii, and the intradermal sporotrichin test was considered positive with a 20 mm induration and erythema. All patients were successfully treated without side effects.
