Thyroid Gland Metastasis From Endometrial Carcinoma Causing Acute Severe Dyspnea

Thyroid metastasis from cervical carcinomas is an extremely rare disease; therefore, only a few cases have so far been reported in the literature. Due to the lack of data and the heterogeneity of clinical cases, the percentage of patients affected by thyroid metastases eligible to undergo surgery is not easily predictable. This report describes a rare case of endometrioid adenocarcinoma metastasized to the thyroid gland. A 72-year-old woman was referred to the ENT department of our hospital (Ospedale Degli Infermi di Biella, Italy) presenting with dyspnea and rapidly worsening condition, in need of emergency surgery. The peculiarity of this case lies in the metastasis isotype rarity, in its voluminous dimension, and in its mediastinal localization, which required the intervention of a multidisciplinary team to establish successful treatment planning.
