ABSTRACT
BACKGROUND: Secondary involvement of the thyroid gland by malignant metastases is uncommon. Acute respiratory crisis due to infiltration of the upper airways is a recognised complication of anaplastic thyroid carcinoma or thyroid lymphoma. Renal cell carcinoma is a tumour that metastasizes diffusely and in an unpredictable manner. CASE PRESENTATION: We report a case of a 73-year-old man with a painful neck mass, dyspnoea, stridor and dysphonia that was evaluated in emergency. A right radical nephrectomy for renal cell carcinoma was performed 8 years previously. An emergency endotracheal intubation was followed by total thyroidectomy. Histological examination confirmed the diagnosis of thyroid metastasis from renal cell carcinoma. CONCLUSION: A literature review regarding emergency treatment for acute respiratory compromise resulting from secondary thyroid tumours was undertaken. Only two cases of metastatic colon cancer and one case of metastatic meningioma requiring emergency thyroidectomy for acute respiratory failure are reported in the literature. This appears to be the first case of emergency surgery performed for acute respiratory compromise due to thyroid metastasis from renal cell carcinoma.

The aim of this study was to retrospectively analyze 5 years' experience of cervico-mediastinal goiters (CMG) management. Twenty-five patients with cervico-mediastinal goiters underwent surgery between January 1998 and December 2002. The group consisted of 16 females and 9 males (mean age, 48.2 years; range, 42-74 years). A total thyroidectomy under general anesthesia was always performed. A no. 7 Fogarty catheter with a 5-ml balloon was employed in the seven last cases to lift the retrosternal portion of the goiter into the neck. The mean postoperative stay was 3 days (range, 1-7 days), and the mean follow-up time was 29 months (range, 1-58 months). There were no postoperative deaths; overall morbidity rate was 28.0%. One patient with a severe life-threatening hematoma required surgical re-exploration. Surgery for CMGs shows a low morbidity rate; total thyroidectomy is the treatment of choice to prevent recurrences or re-surgery for malignancy.
