Thyroid gland is an uncommon site of metastasis, and metastasis to the gland secondary to nasopharyngeal carcinoma is seldom seen. We were only able to identify eight reported cases in the literature. A 61-year-old man, diagnosed case of nasopharyngeal cancer-second primary ( first primary-oropharynx), was found to have a thyroid nodule on routine follow-up positron emission tomography-computed tomography (PET-CT) scan. There was no evidence of metastases at any other sites. The thyroid nodule was confirmed as metastatic carcinoma by fine needle aspiration cytology...

REVIEW
Audrey Tetreault-Laflamme, Juanita Crook
Biochemical failure after primary external beam radiotherapy for prostate cancer is common, and a significant proportion of these failures are due to local residual or recurrent disease. Early or delayed palliation using androgen deprivation therapy is the most common approach. Although a conservative approach is appropriate for many individuals, selected patients would benefit from retreatment with curative intent. We review the pertinent literature on salvage of locally recurrent prostate cancer after primary radiotherapy, including the modalities of surgery, cryotherapy, high-intensity focused ultrasound, or reirradiation with brachytherapy or stereotactic body radiotherapy...
