Due to the anatomical peculiarity of the appendix, diagnosis of @entity5 arising from this area can be challenging by clinicoradiologic means. We report a case of a rare primary @entity2580 with an uncommon presentation. An 86-year-old @entity1 was admitted to our hospital with subacute @entity158 . Computed tomography demonstrated bowel wall thickening with fat stranding in the ileocecal region. The leading diagnostic consideration was @entity29 . Upon colonoscopy, a swollen, distorted ileocecal valve was identified. The remaining colon was otherwise unremarkable. Extensive biopsy sampling of the ileocecal region and colon was performed. A @entity2580 within the ileocecal region was diagnosed on biopsy; there was no @entity1141 or @entity189 of the remaining biopsies. By cytomorphology and immunoprofile, a @entity2580 of appendiceal origin was the primary consideration, further confirmed upon subsequent laparotomy. This case represents an unusual pattern of appendiceal @entity5 spread with localized, @entity14361 , creating a milieu which closely simulates @entity30 on imaging modalities.
