Papillary meningiomas are rare meningeal tumors which are associated with a grim prognosis. These tumors usually recur locally and in some cases they metastasize. The clinical, radiological and histopathological features of a case of a papillary meningioma with a pleural metastasis in a 13-year-old boy are presented. The literature on metastasizing papillary meningiomas is reviewed. Up to now, ...

This is a case report on papillary thyroglossal duct cyst (TGDC) carcinoma along with synchronous occult papillary thyroid microcarcinoma. A 46-year-old woman visited our hospital because she had an anterior midline neck mass below her hyoid bone. Preoperative ultrasound-guided fine-needle aspiration cytology revealed signs of papillary TGDC carcinoma. We performed a Sistrunk operation and a to...

Rabbits, ages 4-24 weeks, were injected with saline or thyroxine (150 micrograms/kg) for 7 days, and force-velocity curves were generated using papillary muscles from these hearts by a method described previously. In addition, the structure and relative amounts of myosin isozymes from papillary muscles and from 3- to 5-mg segments of the left and right ventricular free wall were analyzed by pol...

abstract background: thyroglossal duct cysts (tdc) are the most common congenital neck masses arising from the expansion of the epithelial tract remnants occurring during embryogenic thyroid migration. about 7% of the population have thyroglossal duct remnants. clinical presentation is frequent in children, but adults can also present with thyroglossal duct cysts. thyroglossal duct cysts may ra...

thyroglossal duct cysts are the most common form of congenital cysts on the neck. the incidence of thyroid papillary carcinoma in thyroglossal duct cyst is less than 1%. in most cases the diagnosis is made postoperatively. we present a 22-year-old female with thyroid papillary carcinoma arising from thyroglossal duct cyst,identified in pathologic study after sistrunk operation.in our case there...

background: carcinomas of the thyroid follicular epithelium are the most common cancers of the endocrine system. in the diagnosis of thyroid nodules and tumors, the gold standard is histological evaluation. in cases which have morphological overlap,immunohistochemistry is needed for differential diagnosis. the purpose of this study is to investigate the expressions of cd56,hbme?1, cytokeratin 1...

background and objective: thyroid cancer is the most frequent endocrine malignancy in the world and papillary carcinoma is the most frequent thyroid carcinoma. different markers used for determination of prognosis and vegfr is one of them. the aim of present study was to determine the expression of vascular endothelial growth factor receptor (vegfr) as a prognostic marker in papillary carcinoma...

Although branchial cleft cysts are common, papillary carcinomas arising from them are rare. Here we report a 41-year-old woman with papillary carcinoma originating from a right lateral branchial cleft cyst without any evidence of a papillary carcinoma in the thyroid gland. The patient underwent right lateral neck dissection followed by total thyroidectomy. We then confirmed papillary carcinoma ...

PURPOSE Edwin Beer introduced the first endoscopic treatment of papillary bladder tumors in 1910. This historical review describes how his landmark discovery paved the way for office cystodiathermy to treat recurrent papillary tumors. MATERIALS AND METHODS The medical writings of Edwin Beer and all studies pertaining to the treatment of papillary bladder tumors from 1879 to the present were r...
