Abstract:

Introduction: Pseudomyxoma peritonei (PMP) is a rare mucinous neoplastic condition, typically confined to the peritoneal cavity. Extrapertioneal spread is exceptionally uncommon. Case Presentation: A 76-year-old woman with a history of umbilical hernia repair presented with abdominal pain. Imaging suggested an appendiceal mucocele. During surgery, mucin was unexpectedly found in the extraperitoneal space, in direct contact with a preaponeurotic mesh. Histology confirmed a low-grade appendiceal mucinous neoplasm. Discussion: This case reveals an atypical extraperitoneal extension of PMP, likely facilitated by prior mesh placement. Such rare presentations complicate diagnosis and limit conventional treatment ap-proaches like HIPEC. Conclusion: PMP can exceptionally extend beyond the peritoneum. Surgical history, especially involving im-plants, must be considered in atypical presentations.
