Tungiasis presenting as a soft tissue oral leison.
Abstract
Background: The sand flea Tunga penetrans usually infects the feet and affects primary school-age children and
elderly persons in rural Uganda. Tungiasis occurs nationwide but disease outbreaks have been reported in the
Busoga sub-Region of eastern Uganda, associated with poor sanitation and proximity between humans and
domestic animals. Ectopic tungiasis, usually seen with extensive infection and at weight-bearing body surfaces often
follows exposure in highly infested environments. For patients who present abroad treatment may be surgical
excision or amputation.
Case presentation: An adult female Musoga by tribe, resident in a Kampala City suburb presented at Mulago
National Referral and Teaching Hospital’s Oral Surgery and Jaw Injuries Unit with a discoloured swollen tongue,
facial cellulitis and submandibular lymphadenopathy. A swelling palpable in the body of her tongue was excised
and sent for histology. Tungiasis of the tongue was diagnosed after microscopic examination of formalin-fixed
paraffin-embedded Haematoxylin and Eosin-stained tissue sections.
Conclusion: Lingual tungiasis is a rare diagnosis that was made on histological examination. Atypical presentation
outside an endemic area predisposed the patient to partial glossectomy instead of the less invasive flea
enucleation. Ectopic disease in a city-resident highlights the plight not only of visitors to infested areas but also of
the communities and their domestic animals.
