A carbuncle is a skin infection presenting with multiple boils on the skin. It can occur anywhere in the body caused due to bacteria called Staphylococcus aureus. Carbuncles are commonly seen around the nape of the neck and the back.
It presents with painful boils discharging pus and necrotic (dead cells) material involving the skin and deeper tissue.
There is no exact cause as to why does one get bacterial infection leading to Carbuncle. However persons with diabetes and weakened immunity are more prone to develop a carbuncle.
Carbuncle can increase due to shaving and poor hygienic conditions.
