Cysticercosis is an infestation caused by the larval form of the Taenia solium tapeworm, known as cysticercus cellulosae. Humans can act as either the definitive or intermediate host for this parasite. Consumption of undercooked pork is the primary cause, while other causes include ingestion of food or water contaminated with feces or self-contamination. Intraorally, cysticercosis commonly presents as painless, fluid-filled swellings involving the lips, cheeks, tongue, or masseter muscle that mimic mucoceles. Microscopically, the cysts appear as fibrous capsules surrounding the larval cysticerci. When cyst

1. Cysticercosis
• It is an infestation caused by cysticercus which is a larval form of certain taenia
species. Among 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
Intraorally, 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 .
• The treatment is aimed at the removal of the larvae from the affected area
and flushing the area with normal saline or antiseptics.
