Food material including seeds can be a very common presentation in the appendicectomy specimens. On histological examination they can sometimes be mistaken as worms or their ova. Here we discuss the differentials and differentiating features of common parasites, ova and plant material/seeds found in appendix specimens. A female presented in the emergency unit with abdominal pain, whose diagnostic laproscopy with appendicectomy was done and histology of the appendix showed food material with plant cell matrix along with moderate acute inflammation in the mucosa. Therefore these should be clearly identified in histology by looking at their morphology which can help us in diagnosing and managing the patient appropriately.
