ABSTRACT
Background: The thorax is the most frequent extrapelvic location of endometriosis,
although its incidence has not been sufficiently studied. Its pathophysiology has
not been fully established, but several theories have been put forward. Catamenial
pneumothorax is one of the possible manifestations that make it difficult to establish
the diagnosis and indicate treatment.
Clinical case: A 31-year-old female patient, with a history of repeated spontaneous
pneumothorax, presented for consultation due to dyspnea and chest pain of one month
of evolution. Chest X-ray showed a 50% pneumothorax on the right side and the need
for thoracostomy. Since the episodes of pneumothorax occurred in catamenial phase,
but without being able to establish a clear cause of the clinical picture, diagnostic
thoracoscopy with sampling for histopathological study was performed. During the
procedure multiple pseudonodular lesions of chronic inflammatory aspect were detected
at pleural and lung parenchyma level. The histopathological report was compatible
with pleuropulmonary endometriosis; hormonal therapy was indicated. Given the
satisfactory clinical evolution and postoperative course without complications, the
patient was discharged from the hospital.
Conclusion: Catamenial pneumothorax, as a consequence of pleuropulmonary
endometriosis, is a truly exceptional diagnosis and its suspicion should be linked
to the menstrual cycle. The medical care of patients with this diagnosis should be
interdisciplinary, not only because of the diagnostic strategies but also because of the
complexity of the treatment and its follow-up. The treatment of choice usually requires
surgical interventions, added to the indication of hormonal medication to prevent recurrences,
with favorable success rates. Studies establishing the response of thoracic
ectopic endometrial tissue to medical treatment are pending.
