Long-standingneuropathy in the feet can lead to nonhealing ulcers, abscess formation, andosteomyelitis.
Most of cases showed erosion and ulcer in skin or mucosa, abundant neutrophil infiltrations with microabscess formation.
Extensive acute inflammation may lead to abscess formation, as seen here with rounded abscesses (the purulent material has drained out after sectioning to leave a cavity) in upper lobe and lower lobe.
