This patient presented to the emergency room with a 2-week history of a cutaneous abscess in the left posterior triangle of the neck with surrounding cellulitis. The patient was haemodynamically stable and systemically well. On examination, there was a warm, tender, fluctuant mass measuring 5 cm x 4 cm with a 4 cm rim of surrounding cellulitis.
An x-ray was performed to rule out any involvement of the underlying clavicle. The abscess was incised and drained in the emergency department and the patient was commenced on intravenous antibiotics. Swabs collected cultured methicillin-resistant Staphylococcus aureus (MRSA). The most common causative organism of cutaneous abscesses is Staphylococcus aureus1.
