Summary

Pulmonary endometriosis causing catamenial haemoptysis is often assumed without proof. This case highlights a pulmonary arteriovenous malformation mimicking endometriosis, emphasizing the need for histological confirmation.

Area of Science:

  • Pulmonology
  • Gynecology
  • Pathology

Background:

  • Catamenial haemoptysis is cyclically recurrent coughing up blood, often attributed to thoracic endometriosis.
  • Previous cases of presumed pulmonary endometriosis lacked definitive histopathological evidence.

Observation:

  • A patient presented with catamenial haemoptysis, a symptom typically associated with pulmonary endometriosis.
  • Histological examination of the affected lung tissue was performed.

Findings:

  • The histological findings revealed a pulmonary arteriovenous malformation, not endometriosis.
  • This challenges the long-held assumption that all such cases are solely due to endometriosis.

Implications:

  • Accurate histopathological diagnosis is crucial for understanding the etiology of catamenial haemoptysis.
  • Pulmonary arteriovenous malformations should be considered in the differential diagnosis of cyclical pulmonary bleeding.
  • This finding may necessitate a re-evaluation of previously diagnosed cases of presumed pulmonary endometriosis.
