Guess what! Pseudomonas aeruginosa sepsis

A 62-year-old woman affected by end-stage renal disease secondary to Waldenstrom's disease was admitted to place a central venous catheter for hemodialysis purposes. During the admission, she gradually developed a number of necrotic ulcerative and fluctuant nodular skin lesions on the submammary flexures, groins and limbs accompanied by high fever and chills. Yellow-green purulent material could be drained from the site of introduction of the jugular catheter. Skin biopsies were taken from the edge of an inguinal necrotic-ulcerative lesion and from a fluctuant nodular lesion of the thigh, where pus was drained and cultured.
