We present the case of a 55-year-old white male with biopsy-proven left inguinal lymph node metastasis from differentiated papillary thyroid cancer. Inguinal node metastasis from papillary thyroid cancer is an extremely rare finding. The case demonstrates that papillary thyroid cancer is capable of metastasis presumably through the lymphatic system to unexpected locations.

Background The mitral apparatus contains two myocardial components papillary muscles and the adjacent left ventricular (LV) wall. Delayed enhancement CMR (DE-CMR) enables in-vivo study of potential contributions of LV wall and papillary muscle infarction (PMI) to MR. This study examined the relative impact of papillary muscle and LV wall infarction on mitral regurgitation (MR) following ST elev...

Ectopic thyroid papillary carcinoma presenting as bilateral neck lymph nodes metastasis is very rare. We report a 42-year-old male with midline submental ectopic thyroid papillary carcinoma presenting as bilateral progressively growing neck masses for 3 months. A right neck mass excisional biopsy was carried out and the pathology revealed metastatic papillary carcinoma. Total thyroidectomy, sub...

We report a case of papillary carcinoma in a mediastinal ectopic thyroid diagnosed by endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). In this case, the tumor was adjacent to the central airway; therefore, we attempted to perform EBUS-TBNA to obtain specimens for a diagnosis of papillary thyroid carcinoma. Surgical resection was conducted, and histological evaluatio...

UNLABELLED Papillary muscle rupture is a life-threatening complication of myocardial infarction which is usually refractory to medical treatment. We present a very rare case of a 65-year-old woman who had a myocardial infarction and posteromedial papillary muscle rupture which was only treated with medical therapy, including her corresponding 14-year follow-up. However, surgical intervention is...

BACKGROUND The objective of this study is to determine in a case series (four patients) how calcified deposits in renal papillae are associated with the development of calcium oxalate monohydrate (COM) papillary calculi. METHODS From the recently collected papillary calculi, we evaluated retrospectively patients, subjected to retrograde ureteroscopy, with COM papillary lithiasis. RESULTS Th...

Ependymomas are relatively rare neoplasms of the central nervous system that typically develop along cerebral ventricles and central canal of spinal cord. Occasionally, the tumours of ependymal origin arise supratentorially in brain parenchyma as ectopic cortical mass without any connection to the ventricular system. Ependymomas are heterogeneous group of tumours including cellular, papillary, ...

Glucagon has a positive inotropic effect in normal hearts but is ineffective in animals with chronic cardiac failure. To assess directly the influence of glucagon on the human myocardium, we measured contractility and activation of adenyl cyclase, the enzyme thought to mediate the inotropic action of glucagon, in left ventricular papillary muscles obtained from 12 patients at mitral valve repla...

BACKGROUND In recent years, some reports have suggested that papillary thyroid cancers are more frequently associated with lymphocytic thyroiditis or Hashimoto's thyroiditis. This study investigated a potential increase in the prevalence of chronic lymphocytic thyroiditis among papillary thyroid cancer patients. MATERIALS AND METHODS We used national epidemiological survey data on thyroid can...

Papillary and rhabdoid meningiomas are pathologically World Health Organization (WHO) grade III. Any correlation between clinical prognosis and pathologic component is not clear. We analyzed the prognoses of patients with meningiomas with a rhabdoid or papillary component compared to those of patients with anaplastic meningiomas. From 1994 to June 2013, 14 anaplastic meningiomas, 6 meningiomas ...
