FILARIASIS ??▪ Wuchereria bancrofti, Brugia malayi and Brugia timori – nematodes - lymphatic
filariasis▪ It can affect individuals of all age groups and both sexes▪ Predominantly affects people of low socioeconomic strata▪ Dwell in the subcutaneous tissues and lymphatics of human hosts▪ Transmitted through the bite of blood sucking infected female anopheles mosquito.▪ Lymphangitis, leading to elephantiasis of the legs, arms, scrotum and breast.▪ Oral and perioral soft tissue is uncommon▪ Central giant cell granuloma secondary to filariasis ▪ Biopsy - innocuous radiolucent bony lesions of the maxilla and mandible.

INTRODUCTION
▪ Infectious parasitic disease – tropical and subtropical region of Africa, Asia, Western Pacific, and Central and South America
▪ Categorized into three basic types depending upon tissue of involvment i.e. lymphatic filariasis, subcutaneous filariasis and serous cavity filariasis
▪ Blood-feeding arthropods, black flies and female anopheles mosquitoes act as intermediate hosts .

DISEASE MANIFESTATION
▪ Acute filarial fever▪ Chronic lymphangitis, lymphadenitis,▪ Elephantisis of genitals/legs/arms, ▪ Tropical pulmonary eosinophilia, ▪ Filarial arthritis,▪ Epididimoorchitis▪ Chyluria.▪ EOSINOPHILIA

DRUG OF CHOICE
▪ DEC (diethylcarbamazine) - micro- and macro-filariacidal.▪ Albendazole has also been used in combination with DEC and ivermectin -
anti-helminthic▪ Only two cases have been reported involving oral soft tissue.▪ Filarial worm in bony lesion is not yet reported.

CASE REPORT
▪ 44 year old male – pain since 6 months. ▪ Local physician – antibiotics and
analgesics▪ Intra oral – no swelling.▪ Palpation - tenderness in left maxilla
and body of the mandible▪ 3D computed tomography of the
maxilla and mandible - central giant cell granuloma
▪ General physical examination and hematology - normal

DIAGNOSIS
▪ EXCISIONLA BIOPSY – INTRA ORAL APPROACH▪ MICROSCOPIC EXAMINATION –
▪ Fibrous connective tissue with several epitheloid cell granulomas in the
middle of moderate infiltrates of lymphocytes, plasma cells,
histiocytes, few neutrophils, eosinophils and multinucleated giant cells

DIAGNOSTIC FEATURE WAS THE PRESENCE OF DISINTEGRATING ADULT FILARIAL WORM SURROUNDED BY A MILD INFLAMMATION

FINAL DIAGNOSIS - CENTRAL GIANT CELL GRANULOMA 2° TO FILARIASIS.

TREATEMENT
▪ The patient was started on the antifilarial drug
diethylcarbamazine citrate, 6 mg/kg orally daily for 2 weeks
and the site of the biopsy healed uneventfully, confirming the
filarial involvement of oral tissue in this patient.

DISCUSSION
▪ In world - more than 120 million people infected and one billion people are at risk for infection.
▪ An estimation in 2001 revealed that about 51.7 million people were exposed to the risk of W. bancrofti infection just in India, thus making India the largest filariasis endemic country in world

OTHER CASES
▪ Oral and perioral manifestations of lymphatic filariasis are rare. Rajendran in 2001 and Baliga in 2010 reported cases of filariasis in right and left buccal mucosa of two middleaged
▪ Indian female patients, manifesting as submucosal nodules.

DETECTION MEASURES
▪ Serological antibody tests such as bentonite flocculation, indirect
haemagglutination, ELISA, and indirect fluorescent antibody tests can help in
diagnosis, but they do not differentiate among the various forms of filariasis, or
between past and current infection.

CONCLUSION
▪ More than 150 million people, mainly in developing countries, are affected
by filarial nematode infections that cause debilitating and disfiguring
diseases.
▪ However, the incidence of filariasis in the oral and maxillofacial region is
rare.
▪ Until this report only two cases of filariasis of oral mucosa have been
reported, but central giant cell granuloma secondary to filariasis causing
bone loss in maxilla and mandible is unique and yet to be reported in
English literature.
