BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014204639 DESCRIPTION A full-term male baby with a birth weight of 4.2 kg, large for gestation age, was born to a primigravida mother through caesarean section. The baby was admitted to the neonatal intensive care unit in view of respiratory distress for which he was started on oxygen support. The mother’s antenatal history was significant for gestational diabetes mellitus (controlled through insulin). Maternal history was not suggestive of any fever in the last week of pregnancy or prolonged rupture of membrane or foul-smelling discharge. Antenatal scan was normal. The baby was diagnosed to have reddish desquamation around perioral area, which were painful (figures 1 and 2). He was evaluated with sepsis screening and blood culture in view of suspected sepsis, and was started on antibiotics. Swab culture was sent for bacterial and fungal growth. On day 3, the baby developed honey-coloured crusting around perioral area which confirmed the diagnosis of impetigo contagiosa (figures 3–5). Blood and swab cultures showed no growth. The baby was discharged in good condition and is now in follow-up. Impetigo is defined as an infection of the epidermis by the microorganism. It is mainly seen in infants after the age of 2 months. This is a very serious neonatal infection which needs to be treated aggressively with antibiotics without waiting for laboratory reports. It is classified into two forms: non-bullous/impetigo contagiosa and bullous impetigo. The most common causative organisms are Staphylococcus aureus and group A β haemolytic streptococci (Streptococcus pyogenes). It generally presents as small blisters which rupture and spread (impetigo contagiosa) or erythematous areas. The diagnosis is mainly based on clinical examination of symptoms such as honey-coloured crusting and history of the patient. Treatment is mainly antibiotics (local and systemic) and wound care. 4
