SummaryTwo cases of meningococcemia aro reported. The first one was complicated with meningitis and large areas of ischaemic necrosis of the skin of both shoulders, upper parts of the arms and back. These cutaneous lesions were livid in their central parts and hemorrhagie at their periphery. Later on, they underwent a dry necrosis, forming hard, black eschars which ulcerated in the following days. Pneumonia also occured in the course of the disease. The patient recovered but epidermic grafts were required to heal up the wounds. She was treated with sulfathiazol and later on with penicillin when pneumonia occured.The second was a typical case of very acute meningococcemia with circulatory collaps, suggesting Waterhouse-Friderichsen syndrom. The patient was quite well 18 hours later. Large doses of sulfathiazol, penicillin and desoxy-corticosterone acetate were administered.
