Neoplasia Mucosa Apéndice de Bajo Grado como Hallazgo Incidental Durante la Cesárea: Reporte de un Caso

Área de la Ciencia:

• Gastroenterology; Gynecology; Oncology

Sus antecedentes:

• Appendiceal mucinous neoplasm (AMN) is a rare appendiceal tumor (0.2-0.7%).
• Low-grade AMN (LAMN) often affects women, mimicking appendicitis due to vague symptoms.
• LAMN involves mucin accumulation, appendiceal dilation, and risk of pseudomyxoma peritonei (PMP).

Objetivo del estudio:

• To report a rare case of LAMN incidentally discovered during cesarean section.
• To emphasize the diagnostic challenges of LAMN during pregnancy.
• To highlight the importance of intraoperative vigilance and multidisciplinary management.

Principales métodos:

• Case report of a 45-year-old pregnant woman.
• Incidental intraoperative finding during elective cesarean section.
• Appendectomy, biopsy, CA125 assessment, followed by right hemicolectomy and omentectomy.

Principales resultados:

• LAMN discovered incidentally during cesarean section in a 40-week gestation patient.
• Intraoperative findings included 400 ml of mucin (PMP) and an appendiceal mass.
• Post-operative pathology confirmed LAMN with mucin dissemination.

Conclusiones:

• Incidental LAMN discovery during cesarean section is exceptionally rare.
• Intraoperative vigilance and thorough abdominal assessment are crucial.
• Multidisciplinary management is essential for optimal maternal and neonatal outcomes.
