4. 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.

6. 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 .

7. DISEASE MANIFESTATION
▪ Acute filarial fever
▪ Chronic lymphangitis, lymphadenitis,
▪ Elephantisis of genitals/legs/arms,
▪ Tropical pulmonary eosinophilia,

8. 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.

9. 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

11. 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

14. 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.

15. 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

16. 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.

17. 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.

18. 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. 11/21/2016
