          La esporotricosis es una micosis subcutánea de evolución crónica que puede afectar a humanos y animales, causada por el complejo Sporothrix schenckii, se considera un padecimiento ocupacional y su vía de entrada es a través de traumatismos, es frecuente en niños y adolescentes. Se comunica el caso de una adolescente de 12 años, con historia clínica de un año de evolución de causas no bien identificadas de dermatosis facial localizada en región pre-auricular izquierda, constituida por una placa eritematosa, escamosa, indurada, de bordes definidos. Se confirmó el diagnóstico de esporotricosis cutánea fija por el aislamiento en el cultivo y biopsia de lesión. La paciente fue dada de alta con tratamiento de yoduro de potasio durante dos meses.

          Translated abstract

          Sporotrichosis is a chronic subcutaneous mycosis that can affect humans and animals caused by Sporothrix schenckii complex, it is considered an occupational disease and its route of entry is through injuries, it is common in children and adolescents. A 12-year-old female patient with a lesion of one year of evolution, not well identified causes of facial dermatosis localized in left preauricular region, consisting of an erythematous, scaly, indurated and defined edges. The diagnosis of fixed cutaneous sporotrichosis by isolation in culture and wound biopsy was confirmed. The patient was discharged with potassium iodide treatment for two months.

          Global epidemiology of sporotrichosis.

          Sporotrichosis is an endemic mycosis caused by the dimorphic fungus Sporothrix schenckii sensu lato. It has gained importance in recent years due to its worldwide prevalence, recognition of multiple cryptic species within the originally described species, and its distinctive ecology, distribution, and epidemiology across the globe. In this review, we describe the current knowledge of the taxonomy, ecology, prevalence, molecular epidemiology, and outbreaks due to S. schenckii sensu lato. Despite its omnipresence in the environment, this fungus has remarkably diverse modes of infection and distribution patterns across the world. We have delved into the nuances of how sporotrichosis is intimately linked to different forms of human activities, habitats, lifestyles, and environmental and zoonotic interactions. The purpose of this review is to stimulate discussion about the peculiarities of this unique fungal pathogen and increase the awareness of clinicians and microbiologists, especially in regions of high endemicity, to its emergence and evolving presentations and to kindle further research into understanding the unorthodox mechanisms by which this fungus afflicts different human populations.

            Clinical practice guidelines for the management of sporotrichosis: 2007 update by the Infectious Diseases Society of America.

            Guidelines for the management of patients with sporotrichosis were prepared by an Expert Panel of the Infectious Diseases Society of America and replace the guidelines published in 2000. The guidelines are intended for use by internists, pediatricians, family practitioners, and dermatologists. They include evidence-based recommendations for the management of patients with lymphocutaneous, cutaneous, pulmonary, osteoarticular, meningeal, and disseminated sporotrichosis. Recommendations are also provided for the treatment of sporotrichosis in pregnant women and in children.

              Sporotrichosis: An Overview and Therapeutic Options

              Sporotrichosis is a chronic granulomatous mycotic infection caused by Sporothrix schenckii, a common saprophyte of soil, decaying wood, hay, and sphagnum moss, that is endemic in tropical/subtropical areas. The recent phylogenetic studies have delineated the geographic distribution of multiple distinct Sporothrix species causing sporotrichosis. It characteristically involves the skin and subcutaneous tissue following traumatic inoculation of the pathogen. After a variable incubation period, progressively enlarging papulo-nodule at the inoculation site develops that may ulcerate (fixed cutaneous sporotrichosis) or multiple nodules appear proximally along lymphatics (lymphocutaneous sporotrichosis). Osteoarticular sporotrichosis or primary pulmonary sporotrichosis are rare and occur from direct inoculation or inhalation of conidia, respectively. Disseminated cutaneous sporotrichosis or involvement of multiple visceral organs, particularly the central nervous system, occurs most commonly in persons with immunosuppression. Saturated solution of potassium iodide remains a first line treatment choice for uncomplicated cutaneous sporotrichosis in resource poor countries but itraconazole is currently used/recommended for the treatment of all forms of sporotrichosis. Terbinafine has been observed to be effective in the treatment of cutaneous sporotrichosis. Amphotericin B is used initially for the treatment of severe, systemic disease, during pregnancy and in immunosuppressed patients until recovery, then followed by itraconazole for the rest of the therapy.
