Fluke [F. Hepatica] In The Neck
I’ve come across publications citing unusual occurrences where parasites migrate into different parts of the body. Below is an abstract on a fluke found within a tumor, in the cervical region. Flukes are typically found in the liver or intestines.
Cervical tumor caused by the sexually mature stage of Fasciola hepatica

16 October 2008.
A 58-year-old man presented with an asymptomatic 5cm left anterior cervical tumor that had been present for over a year. Histological analysis revealed chronic inflammation and granuloma with giant cells surrounding Fasciola hepatica eggs. Fas2 antigen was detected in the tissue by immunohistochemistry. Serology for F. hepatica was positive, but stool examinations were negative and eosinophil count was normal. A month later, the tumor recurred, and an adult parasite was found during excision. The patient received triclabendazole, and after 6 months serology was negative. Erratic localization of F. hepatica reveals a pathology involving chronic inflammation caused by a sexually mature parasite, although according to theory only immature parasites are located in ectopic lesions.

You can see a picture of the type of fluke cited in the abstract above, here.
This is from Healthline on information about flukes.
Fluke infections are diseases of the digestive tract and other organ systems caused by several different
species of parasitic flatworms (Trematodes) that have complex life cycles involving hosts other than human beings. Trematode comes from a Greek word that means having holes and refers to the external suckers that adult flukes use to draw nourishment from their hosts. Fluke infections are contracted by eating uncooked fish, plants, or animals from fluke-infected waters. Symptoms vary according to the type of fluke infection.
In humans, fluke infections can be classified according to those diseases caused by liver flukes and those caused by lung flukes. Diseases caused by liver flukes include fascioliasis, opisthorchiasis, and clonorchiasis. Cases of liver fluke infection have been reported in Europe and the United States, as well as the Middle East, China, Japan, and Africa. Diseases caused by lung flukes include paragonimiasis. Paragonimiasis is a common infection in the Far East, Southeast Asia, Africa, Central and South America, Indonesia, and the Pacific Islands. It is estimated that between 40 million and 100 million people worldwide suffer from either liver or lung fluke infections.
In their adult stage, liver and lung flukes are symmetrical in shape, ranging between 1/4–1 in in length, and look somewhat like long, plump leaves or blades of grass. They enter through the mouth and can infect any person at any age.
Causes and symptoms
The symptoms of fluke infection differ somewhat according to the type of fluke involved. All forms of liver and lung fluke infection, however, have the following characteristics:
* most persons who get infected do not develop symptoms (asymptomatic)
* the early symptoms of an acute fluke infection are not unique to these diseases alone (nonspecific symptoms)
* infection does not confer immunity against re-infection by the same species or infection by other species of flukes
* infection is usually associated with eating uncooked fish, plants, or animals that live in fresh water.
