1. C ysticercosis It is an infestation caused by cysticercus which is a larval form of certain taenia species. A mong various species the larval form of tape worm, the Taenia solium i.e. cysticercus cellulosae infest human beings either as a definitive or intermediate host. Consumption of inadequately cooked pork- primary cause. Fecally contaminated food or water as well as self contamination by reflux- other causes I ntraorally, cysticercosis commonly involves lips, cheeks, and tongue . Cysticercosis involving the masseter muscle has also been reported Most cases present as solitary or multiple, painless, well circumscribed, fluctuant swellings, and often mimic mucoceles. Microscopically it appears as a fibrous capsule surrounding a cysticercus. The bladder wall appears as lightly eosinophilic wavy membrane with multiple tiny ovoid nuclei in the fibrillary stroma beneath

2. When a cyst dies spontaneously or following chemotherapy, there is usually more inflammation. Local eosinophilia, granulation tissue, and a granulomatous reaction follow.

3. Oral myiasis Oral myiasis is defined as a condition in which the soft tissues of different parts of the oral cavity are invaded by the parasitic larvae of flies. These larvae commonly known as maggots are of Diptera. Myiasis is associated with poor oral hygiene. Usually the female fly infests ova in open wounds, dead tissue or normal body cavities. These eggs hatch and the larvae get their nourishment from the soft tissue. It is relatively a rare condition but cases have been reported in gingiva, palate and extracted wounds. The usual presenting symptoms are painful growth with ulceration and itching due to crawling movement of the larvae . T he treatment is aimed at the removal of the larvae from the affected area and flushing the area with normal saline or antiseptics.
