ABSTRACT Primary non-carcinoid
adenocarcinoma of the appendix is rare. Likewise, distant
metastatisis of another organ or system cancer is even more rare.
Generally, gastric adenocarcinoma may clinically be detected while it
is spreaded. A 31-year-old man who had no specific medical history
was admitted to the clinic with complaint of right lower abdominal
quadrant pain and rebound tenderness over McBurney’s point.
Laparotomy was performed for a diagnosis of acute appendicitis.
Histopathological examination revealed an obstruction of the
appendicular lumen due to adenocarcinoma metastasis. Correspondingly,
the patient was re-evaluated to detect the primary malignancy focus
and underwent inoperable gastric adenocarcinoma diagnosis. As our
knowledge, there is only one other example in the literature; a
patient with undiagnosed gastric cancer who had an acute appendicitis
as the first clinical manifestation of an upper gastrointestinal
malignancy. Thus we want to share this unusual, interesting and
complicated case.
Key words: Acute appendicitis, Gastric
adenocarcinoma, Distant metastasis, Diagnostic laparoscopy
