This case describes a young male patient, who presented to the surgical emergency department with clinical and computed tomography signs of acute appendicitis. Laparoscopic appendectomy was performed. The final histopathological examination revealed a bone metaplasia of the distal appendix, without any other associated appendiceal pathology.
