A Case of Appendicular Adenocarcinoma Presenting as Acute Appendicitis

Primary adenocarcinoma of the appendix is a rare malignancy, accounting for less than 1% of gastrointestinal neoplasms. The clinical presentation of appendiceal tumours is variable and non specific. Acute appendicitis from luminal obstruction is the most common presentation. Hereby, the authors present a case of 60-year-old female presented with chief complaint (c/o) of abdominal pain for duration of two months, exhibiting clinical findings of tenderness in right iliac fossa. She was diagnosed with acute appendicitis based on clinical and radiological evidence. A laparoscopic appendicectomy was done and specimen sent for Histopathological Examination (HPE), which showed features of adenocarcinoma. As part of evaluation, Contrast-enhanced Computed Tomography (CECT) was taken and tumour markers were sent, showed no abnormal findings. Patient subsequently underwent right hemicolectomy, which is the standard protocol for adenocarcinoma of the appendix. Very minimal cases are reported till now. The present case report will discuss the management and presentation of appendicular adenocarcinoma.
