Summary
Peritoneal pseudo-myxoma, likely from an appendiceal mucocele, can spread to the pleura. Histology confirmed these pleural metastases were identical to the primary peritoneal disease.
Area of Science:
- Gastroenterology
- Oncology
- Thoracic Surgery
Background:
- Peritoneal pseudo-myxoma is a rare condition characterized by mucinous ascites.
- Appendiceal mucocele is a common precursor, though other origins exist.
- Metastatic spread to distant sites like the pleura is uncommon.
Observation:
- A 69-year-old man presented with recurrent peritoneal pseudo-myxoma.
- Computerised tomography revealed nodular, unilateral, and asymptomatic pleural metastases.
- The patient underwent thoracotomy for pleural mass biopsy.
Findings:
- Histological examination of pleural fragments demonstrated lesions identical to peritoneal masses.
- This confirmed the pleural lesions as metastases from the primary peritoneal disease.
- The appendiceal origin was strongly suspected based on the clinical presentation.
Implications:
- This case highlights the potential for peritoneal pseudo-myxoma to metastasize to the pleura.
- Asymptomatic pleural metastases can be detected via advanced imaging during disease surveillance.
- Histopathological correlation is crucial for confirming metastatic disease and guiding treatment.
