[Haemoptysis in children: diagnose and act]

Area of Science:

• Pediatric Pulmonology
• Rare Pediatric Symptoms

Background:

• Hemoptysis, or coughing up blood, is an uncommon yet anxiety-provoking symptom in children.
• Identifying the cause of pediatric hemoptysis can be challenging for clinicians.

Observation:

• Two adolescent cases presented with acute dyspnea and hemoptysis.
• Case A involved tuberculosis-induced hemoptysis, a rare cause in the Netherlands.
• Case B was diagnosed with pseudohaemoptysis, requiring differentiation from true hemoptysis.

Findings:

• While often self-limiting, pediatric hemoptysis necessitates a thorough diagnostic approach.
• Tuberculosis can manifest as hemoptysis in children, even in low-prevalence regions.
• Distinguishing pseudohaemoptysis from true hemoptysis is critical for accurate diagnosis.

Implications:

• Understanding diverse causes of pediatric hemoptysis is vital for timely diagnosis.
• Appropriate diagnostic workup ensures prompt initiation of treatment for severe cases.
• This knowledge aids physicians in managing hemoptysis and alleviating patient/parental anxiety.
