<jats:p>Bleomycin has progressively been used to treat low-flow vascular malformations in children. No significant systemic side effects have been reported in large series after low doses, but some authors are still concerned about its use. We report a case of a severe acute lung toxicity after a low dose of a second bleomycin intralesional injection in a 5-year-old girl. She had no risk factors and presented a cervical low-flow venous malformation. Twenty-four hours after this second administration, she presented with fever and respiratory distress. A chest radiograph showed bilateral opacities and computerized tomography revealed extensive and diffuse lung ground-glass opacities. The patient started to receive intravenous methylprednisolone, but she experienced progressively increased dyspnea, and montelukast was added. She improved and was discharged from the hospital without oxygen support, with montelukast and prednisolone for tapering doses during months. Five months after onset, the patient is developing well, is active, and walks and talks without dyspnea. A new low-dose computed tomography shows improvement in radiologic findings. This is the second case of pulmonary toxicity observed in a child after bleomycin intralesional administration, and the first reported after the lowest dose of this drug to date (7 mg: 0.28 mg/kg; 10 U: 0.4 U/kg). A delay in the diagnosis and treatment of this complication can be fatal. Any physician who treats these patients must be alert and consider this complication in children with respiratory symptoms after bleomycin sclerotherapy. Early detection of pulmonary toxicity would allow prompt therapy and could avoid pulmonary damage.</jats:p>
