Majocchi’s granuloma is a folliculitis caused by dermatophytes, which is most commonly located on the skin of the lower limbs in women. A favorable factor for the infection is an injury caused by epilation, which, together with an existing fungal infection, can lead to the spread of folliculitis to other parts of the body. The disease is extremely rare (Burgdorf et al., 2010). The aim of this article is to describe the case of a patient who developed severe edematous lesions of the lower extremities from a mycosis infection with Trichophyton mentagrophytes varietas granulosum, the carrier of which was a domestic guinea pig.
