Hydatid cyst of the buccal mucosa: An unusual presentation

Abstract

Hydatid cyst is a parasitic cyst caused by the tapeworm Echinococcus that occurs primarily in sheep grazing areas worldwide. It is a chronic disease, and the cysts can be localized in unusual anatomical and geographic locations. It is known to affect the head and neck region. Patients must undergo a thorough systemic investigation as 20–30% show multiorgan involvement. We report a case of hydatid cyst occurring in the buccal mucosa of a 45- year -old male presenting as a small asymptomatic lump and emphasize on its rarity and diagnostic issues.

Hydatid cyst involving the mandible ramus

“…It is known to commonly affect the cattle-raising population. 8 On inquiry, the patient reported a history of raising goats at home. The larval form of the parasite is mostly transmitted through ingesting contaminated food.…”

“…The liver (50-70%) is the most commonly affected organ, followed by the lungs (20-30%), spleen (0.7- 8%), kidney (7%), muscles (4%), central nervous system (0.2-3%), and heart (0.2-2%). 8 Intraosseous involvement is seen in <3% of cases. Furthermore, 2-6% of the total intraosseous cases affect the maxillofacial region.…”

Hydatid cyst of parotid: Report of unusual cytological findings extending the cytomorphological spectrum

“…The common localization of hydatid cysts is in liver and lungs (80%). It is estimated that 1–2% manifest in the head and neck region and may be subjected to FNA. The identification of acellular laminated membranes, protoscolices, and scattered small hooklets establishes the cytological diagnosis of hydatid cyst .…”
