ABSTRACT VIEWER

A case of thyroid swelling occurring in a 30 years old male, diagnosed as primary hydatid cyst of thyroid gland by fine needle aspiration cytology (FNAC) is being reported for its extreme rarity. The FNAC diagnosis of hydatid cyst of thyroid gland was made with certainty by the presence of fragments of hyaline laminated cell wall membrane, scolices, hooklets and few brood capsules in a background of cellular debris in the smears. The possibility of hydatid cyst should be kept in mind during the FNAC of a cystic lesion, even in an unusual location for it. Preoperative FNAC diagnosis of hydatid cyst will be helpful to take appropriate anti-anaphylactic measures and necessary care to avoid the spread of protoscolices during surgical extirpation of the cyst.
