Prognostic factors of recurrence in encapsulated Hurthle cell carcinoma of the thyroid gland

Follicular carcinomas of the thyroid gland, including its oncocytic variant (so‐called Hurthle cell carcinoma), are subdivided into the indolent encapsulated (“minimally invasive”) and the clinically aggressive widely invasive tumors. There are, however, cases of encapsulated follicular carcinoma that recur and metastasize. Identifying these cases at the time of diagnosis is crucial for prognostic and therapeutic considerations. Because to the authors' knowledge most studies do not focus exclusively on the encapsulated Hurthle cell carcinoma (EHC), the current study attempted to identify predictors of recurrence in EHC.
