The condition is generally caused by the bacteria Group A (beta-hemolytic) Streptococcus (GAS), Staph. aureus, and sometimes both. It is associated with poor hygiene and poor nutrition. Ecthyma gangrenosum is a more severe type caused by Pseudomonas septicaemia. The very young, elderly and those with weakened immune systems are more susceptible to ecthyma.
Treatment requires antibiotics, applying antiseptics and improving hygiene and nutrition. Fusidic acid or mupirocin ointments can be applied three times daily to the ulcers, after removing the crusts. Crusts can be removed by applying gentle pressure for 10-minutes at a time, several times a day, with a cloth soaked in a mixture of half a cup of white vinegar in a litre of water. Other options include applying antiseptics such as povidone iodine, superoxidised solution, antibacterial Manuka honey or hydrogen peroxide cream. Flucloxacillin or dicloxacillin can be given by mouth.
The condition occurs in all ages, and in both males and females.
