Surgical management of pulmonary metastases in pseudomyxoma peritonei: a case series highlighting the challenges of non-palpable lesions and surgical margin management.

ABSTRACT:

Background

Pseudomyxoma peritonei (PMP) is a rare neoplastic disease that can occasionally present with pulmonary metastases as an even rarer manifestation. Although cytoreductive surgery represents the primary treatment option for PMP, surgical management of pulmonary metastases presents unique challenges owing to their mucinous nature. The aim of this case series was to present key considerations for the surgical management of PMP lung metastases, particularly regarding solid-appearing nodules that are impalpable during surgical resection, requiring more extensive resection owing to the risk of recurrence.

Case presentation

Between November 2013 and May 2023, we performed a total of 13 surgical procedures for pulmonary metastases in seven patients with PMP at our instituti
