Introduction and importance: Hydatid cysts are often found in the liver or lungs. As for the parotid localization, it remains exceptional even in endemic areas and presents as a tumor of the parotid thus representing a challenge to the practitioner.
Case presentation: A 54-year-old male farmer presented with a swelling in the left parotid gland region evolving over the past 2 years. Physical examination revealed a non-tender and mobile swelling in the left parotid region, the overlying skin was normal. Magnetic resonance imaging showed a cystic lesion of the left parotid gland. Fine-needle aspiration cytology (FNAC) yielded a clear fluid with a few benign epithelial cell. A superficial parotidectomy was performed. Histopathological examination confirmed the presence of a hydatid cyst in the parotid gland.
Clinical discussion: Parotid hydatid cyst is exceptional. However, it can be suspected in the context of an isolated parotid cystic mass in an endemic area, even in the absence of any other associated location.
Conclusion: Hydatid cysts of the parotid gland have a polymorphic and a specific symptomatology and require surgical removal.
