Hydatid cyst in submandibular salivary gland

This case of 52-year male with swelling in the left submandibular area for 1 year came to ENT OPD of Patna medical college, Patna. Clinical examination showed swelling to be multiple nontender cysts with enlarged submandibular salivary gland. CT-scan revealed large well-defined encapsulated multicystic lesions in the left submandibular gland. FNAC was suggestive of aspirate to be ectopic to that area. Excision biopsy was done. HPE showed features suggestive of parasitic infestation along with chronic sialadenitis. Gross picture and investigations were highly suggestive of parasitic infestation to be primary hydatid cyst of the gland. Scanning for other areas like liver and lungs done, no lesion was found.
