Occurrence of a desmoid tumour in a status post appendicectomy: A case report

Introduction and importance: Tumours arising from previous sites of appendicectomy are a rare phenomenon. There have been few documented cases in literature but for the most part, it is a rare occurrence that needs further investigation.

Case presentation: A 20-year-old male presented to our outpatient with a large mass in his right upper abdomen for 2 months and a history of an appendicectomy done in an outside hospital 4 years prior.

Clinical discussion: After regular investigations, the tumour was resected with adequate margins. On immunohistochemistry, the specimen was said to be of a desmoid fibromatosis. The exact aetiology of the disease cannot be determined unless we get a thorough analysis of the appendix specimen.

Conclusion: This paves the way to the learning curve, which is that we must ensure proper patient follow-ups with relevant histopathological reports to ensure complete and comprehensive care to the patient.
