A histopathological surprise of retroperitoneal tumor

Abstract

Metastatic papillary carcinoma of thyroid in euthyroid patient surprisingly presented as retroperitoneal mass. The rarity of the lesion, non specific symptoms ad signs made the pre operative diagnosis very difficult, but the histological report made the case very interesting. However because of the rarity of the presentation the diagnosis and management is not clearly defined and hence the associated patient outcome also. Till our knowledge through this paper we are presenting the first case of metastatic papillary carcinoma of thyroid which presented as retroperitoneal tumor.
