Pyriform sinus fistula (PSF) is an anomaly that can arise due to failure of involution of the third or fourth branchial cleft during embryogenesis. It can manifest clinically as sinuses, cysts, or abscesses in the neck and is common in childhood. Herein, we describe a neonate who presented with neck swelling and respiratory distress, which was secondary to a fourth branchial pouch sinus. Physical examination revealed swollen areas in the posterolateral pharyngeal wall and on the external left side of the neck. Computed tomography imaging showed a left-sided mass that was filled with air and fluid. Eventually, the pyriform sinus cyst and the entire fistulous tract were excised. The postoperative course was uneventful. Follow-up after 18 months showed no recurrence.

Metastasis of thyroid cancer to the sternum is rare. Ablation is the therapy of choice for patients with metastasizing differentiated thyroid cancer, while surgical resection is an option for those with resectable bony metastasis. This report describes a case of a 65-year-old woman with a sternal tumor. The patient was treated by partial sternal resection and sternal reconstruction with new material polypropylene/expanded polytetrafluoroethylene (ePTFE) composite. The postoperative course was uneventful, and she was free of recurrence after 1 year of follow-up. We conclude that surgery should be used to manage solid bony metastasis from thyroid papillary carcinoma. Further more, a polypropylene/ePTFE composite may be useful for sternal reconstruction after thoracotomy. [ABSTRACT FROM AUTHOR]

Giant cell reparative granuloma (GCRG) is an uncommon and nonneoplastic reactive tumor that involves themaxilla and mandible in the region of the head and neck. It is rare in the nasal cavity, and it might be misdiagnosed. We reported a very aggressive GCRG with intracranial invasion, which was treated surgically via a combined approach of a lateral rhinotomy with a craniotomy by bilateral coronal incision. The pathology was consistent with GCRG. A short literature review about diagnosis, clinical behavior, and treatment of this tumor entity is given. [ABSTRACT FROM AUTHOR]
