Sporotrichosis is caused by the thermodimorphic fungi of the genus Sporothrix. It is the most common cutaneous mycosis in Latin America, but it is considered uncommon in pregnancy. We report a pregnant woman with with an exuberant ulcerated plaque that proved to be localized sporotrichosis. Therapy choice is a difficult decision in this group of patients. In this case, there was complete resolution of the infection after delivery, without any therapeutic intervention.
