Resumen
Se presenta un caso clínico de pitiriasis versicolor por M. pachydermatis en una paciente de 11 años de edad, diagnosticado mediante clínica, morfofisiología y biología molecular. Malassezia pachydermatis es parte de la microbiota común de diversos mamíferos domésticos y animales salvajes. En éstos se reconoce como agente causal de dermatitis y otitis externa. En humanos se han descrito escasas infecciones ya sea superficiales como invasoras, lo que puede atribuirse a la difícil transmisión y adaptación a partir de los animales domésticos. Se comentan los aspectos biológicos y epidemiológicos de esta infección zoonótica.
A clinical case of pityriasis versicolor caused by M. pachydermatis in an 11 year old patient which was diagnosed by means of clinic, morphophysiology and molecular biology is presented. Malassezia pachy dermatis is part of regular microbiota in several domestic mammals as well as wild animals. It is recognized as the causing agent of dermatitis and external otitis in the latter. As to human beings, superficial infections have rarely been given an invasive character what can be explained by the difficult transmission and adaptation coming from domestic animals. Biological and epidemiological aspects of this zoonotic infection are described.
