Papillary thyroid carcinoma is a common thyroid malignancy reported world wide. It affects females more commonly in the 4th to 6th decades of life. The patients usually present with a painless anterior neck mass and occasionally with lymph node involvement. We report a case of an elderly male who presented with hoarseness and hemoptysis, which warranted bronchoscopy. Biopsy of the intraluminal ...

The tracheal epithelium of the Fischer 344 rat is histologically very similar to that of the human bronchus. Also, carcinomas of tracheal origin in F-344 rats are similar in morphology to human bronchogenic carcinomas. Tumor promotion in rat tracheal epithelium was studied by using two model systems. The first is a heterotopic transplant system in which rat tracheas are implanted subcutaneously...

A 37-year-old male athlete was diagnosed with primary tracheal adenoid cystic carcinoma following investigation for dyspnea, wheeze, and eventual stridor. Preoperative bronchoscopy revealed a highly vascular tumor 4 cm distal to the cricoid with no gross disease extending to the carina. Imaging revealed circumferential tracheal irregularity immediately inferior to the cricoid, with no definite ...

  Introduction: Tracheal stenosis is normally caused by trauma, infection, benign and malignant tumors, prolonged intubation or tracheostomy. The best treatment for tracheal stenosis is resection and anastomosis of trachea. Yet the major surgical complication of tracheal surgery is postoperative stenosis. The goal of this paper is to study the result of tracheal stenting as a replacement therap...

The thyroid gland is an uncommon site for distant metastases from extra-cervical tumors. Malignant melanoma and kidney, lung, breast, and gastrointestinal carcinomas are the most common origins of these rare metastases. We report the case of a patient with rapidly progressive thyroid metastasis from a lobular breast carcinoma operated on three years previously. An 83-year-old female patient und...
