Difficult differential diagnosis of delayed mesh infection following inguinal hernia surgery involving appendiceal cancer: A case report

Abstract

IntroductionWe present a case of post-inguinal hernia repair delayed mesh infection that was initially misdiagnosed as appendiceal cancer. Presentation of caseThe patient was an 82-year-old man who underwent right inguinal hernia repair with a plug mesh 7 years before he presented with a lump in the right inguinal region. No skin infection signs were evident; blood tests revealed no inflammation or abnormal tumor markers. Abdominal contrast-enhanced computed tomography revealed a tumorous lesion in the right lower abdomen, raising the suspicion of appendiceal cancer with lymph node and lung metastases. Lower gastrointestinal endoscopy revealed extrinsic cecal wall compression. During laparoscopic ileocecal resection with lymph node dissection, a pus-filled abscess exposed the mesh in the inguinal region; hence, a diagnosis of a mesh infection was made. There were no macroscopic cancer signs in the appendix or cecum. Partial cecal resection involving the infected mesh was performed. Pathological tests did not reveal cancer, confirming the delayed mesh infection diagnosis. DiscussionThis case presents the diagnostic challenges posed by post-inguinal hernia repair delayed mesh infections, emphasizing the lack of typical clinical and imaging indications and the potential for misdiagnosis as appendiceal cancer. It also highlights the importance of early recognition and appropriate management of these infections. ConclusionThis case emphasizes the complexity of diagnosing post-inguinal hernia repair delayed mesh infections. These infections may mimic other conditions such as appendiceal cancer, stressing the need for vigilance and careful evaluation. Early recognition and proper management are essential to avoid unnecessary extensive surgeries.
