Splenectomy for Solitary Splenic Metastasis in Recurrent Papillary Thyroid Cancer. A Case Report and Literature Review

الملخص EN

Thyroid cancer is the most common endocrine malignancy, presenting with 23 500 new cases per year in the United States.

About 7-23% of the patients will present recurrent metastases disease during follow-up.

The classic variant of papillary carcinoma is less aggressive compared to its other variants like diffuse sclerosing, tall cell or columnar cell, and insular variants, and the sites to which this metastasizes is already well identified.

Metastasis to the spleen is an extremely rare manifestation of papillary thyroid cancer.

To date, only 3 cases have been reported in the literature.

Herein, we present a 52-year-old male, who developed spleen metastases, 2.4 years after total thyroidectomy and central neck dissection followed by radioactive iodine ablation and seven months after treatment with sorafenib for lung metastases.

The splenic lesion was detected in surveillance studies.

This case highlights that splenic metastasis, although rare, may occur even in a patient with a locoregional and systemic controlled thyroid cancer and that it can be treated safely with surgical resection.
