Lymphangitic sporotrichosis caused by cat scratch in an area of eastern Mexico

Abstract

Sporotrichosis is an endemic mycosis caused by the di-morphic fungus Sporothrix schenckii sensu lato. This phe-nomenon has gained prominence in recent years due to its global prevalence, the recognition of multiple cryptic spe-cies within the originally described species, and its distin-ctive ecology, distribution, and epidemiology worldwide. Sporotrichosis, a human and animal disease caused by the Sporothrix species, is the most prevalent implantation mycosis worldwide. The classification of Sporothrix has undergone signi-ficant refinement in recent years, resulting in substantial pro-gress in the fields of diagnosis, epidemiology, and treatment. Material and methods: we present the clinical case of a 15-ye-ar-old male, who was scratched by his cat on the back of the right hand, after 5 days developed erythematous-violaceous lesions. Sporothrix schenckii sensu stricto was diagnosed as the causal agent of both infections by using microbiological and proteomic tools (mycological culture and MALDI-TOF). Itraconazole 200mg twice daily for three months was prescribed with excellent clini-cal improvement.
