Facial gangrenous ecthyma: case report

Ecthyma gangrenosum is a necrotizing skin infection caused by gram-negative bacteria, mainly Pseudomonas aeruginosa (PA). It is associated with the presence of bacteremia due to PA, in immunocompromised patients.1 It is characterized by producing ulcers surrounded by an erythematous halo, and as it progresses, a black eschar is also added.2 A differential diagnosis should be made with acute invasive fungal rhinosinusitis, which also occurs in immunocompromised patients. The initial symptoms are usually not very specific, including fever, nasal obstruction and rhinorrhea. The aim of this report is to present the case of a male patient diagnosed with multiple myeloma who presented a facial Gangrenous Ecthyma due to Pseudomonas aeruginosa, with rhinosinusal onset.
