We report a term baby who presented soon after delivery with bilateral tender scrotal swelling with skin discolouration, which was subsequently diagnosed as rapidly progressive cellulitis. The scrotal swelling was treated as cellulitis with a broad spectrum of antibiotics, covering anaerobes, considering the absence of signs and ultrasonographic features of testicular torsion. He also had meconium aspiration pneumonia, complicated by pulmonary hypertension, and required non-invasive oxygen supplementation and intravenous antibiotics. The swelling slowly improved over 2 weeks without complications. In conclusion, early diagnosis and proper antibiotic treatment are essential to prevent the spread of infection and serious complications. .
