Confirmación de Streptococcus suis en Chile

Sporotrichosis is a subcutaneous mycosis caused by Sporothrix complex, endemic in Abancay, Peru. Is acquired by traumatic inoculation with plant material. Common clinical presentations are lymphatic cutaneous and fixed cutaneous disease. We report 2 cases of fixed cutaneous sporotrichosis with granulomatous appearance. The first case was a patient of 65 years old with no risk factors and the second case was a 67 year old diabetic patient. Subjects underwent mycological culture with Sabouraud agar, with isolation of Sporothrix schenckii and clinical dignosis of fixed cutaneous sporotrichosis with granulomatous appearance. One patient received oral treatment with saturated solution of potassium iodide (SSKI) with a initial dose of 3 drops tid up to a maximum dose of 40 drops tid. Mycological and clinical cure was achieved after 2 months of treatment. We should consider the unusual clinical presentations of fixed cutaneous sporotrichosis with granulomatous appearance that present morphological and clinical features in diabetic and nondiabetic patients older than 60 years from endemic areas and communicate adequate response to treatment with SSKI in one case. La esporotricosis es una micosis subcutanea ocasionada por el complejo Sporothrix, endemica en Abancay, Peru. Se adquiere por inoculacion traumatica con material vegetal. Las formas clinicas comunmente descritas son la cutanea linfatica y cutanea fija. Presentamos dos casos de pacientes adultos con una esporotricosis cutanea fija granulomatosa. El primer caso era una paciente de 65 anos de edad, sin antecedentes de riesgo y el segundo era una paciente de 67 anos, diabetica. El diagnostico se realizo por cultivo micologico aislandose Sporothrix schenckii. Un caso se trato con solucion saturada de yoduro de potasio (SSKI), via oral, alcanzando la cura micologica y clinica tras dos meses de tratamiento. La otra paciente no acudio a tratamiento. Se revisan las presentaciones clinicas inusuales de la esporotricosis cutanea fija y la forma granulomatosa que presenta caracteristicas morfologicas y clinicas poco habituales en pacientes diabeticos y no diabeticos mayores de 60 anos provenientes de zonas endemicas.
