CONTEXT An intraductal oncocytic papillary neoplasm is a rare pancreatic tumor with the potential of developing invasive carcinoma. Its differentiation from other cystic-like neoplasms of the pancreas, such as intraductal papillary mucinous neoplasms, is a challenge for pancreatic imaging. CASE REPORT We present the case of a 76-year-old male with painless jaundice caused by an intraductal on...

Papillary breast lesions encompass a wide spectrum of pathologies ranging from benign lesions, such as solitary intraductal papilloma, to the uncommon papillary carcinoma. These lesions have various clinical presentations and diverse radiological features. Differentiating benign and malignant papillary lesions based on imaging features may often be difficult. Other benign and malignant patholog...

The aim of the present study was to investigate the association of extracellular matrix metalloproteinase inducer (EMMPRIN) and human epidermal growth factor receptor (HER)-2 protein expression in papillary thyroid carcinoma with lymph node metastasis (LNM), as well as the correlation between the two types of protein expression. A quantum dot-based immunofluorescence technique was used to detec...

Well-differentiated papillary and follicular thyroid carcinomas are the two most common types of thyroid cancer. Although cancerous cells in both types phenotypically resemble the epithelial follicular cell, the tumors display different histological characteristics and clinical outcomes. Molecular defects contributing to the separate development pathways remain largely unclear. We evaluated gen...

Immunohistochemical Comparison of p53 Expression, Intensity and Distribution in Different Papillary Urothelial Cancers

PURPOSE We aimed to estimate the upgrading rate of core-needle biopsy (CNB)-diagnosed papillary breast lesions to atypical or malignant papillary lesions on subsequent surgery. MATERIALS AND METHODS We performed a retrospective review of medical records and imaging findings of patients diagnosed by CNB as having papillary lesions from January 1, 2005 to May 31, 2011. Outcomes were determined ...

A technique is described to localize the anterolateral papillary muscle and to assess its performance in vivo. Using this technique, we measured sequentially the pressure generated within the anterolateral papillary muscle and its changes in length during the cardiac cycle in eight open-chest anesthetized dogs. Pressure within the anterolateral papillary muscle was measured with a 1.6 mm diamet...

Papillary fibroelastomas are cardiac benign tumours. Among the benign cardiac tumor, papillary fibroelastomas are reported second after myxomas. Most often diagnosed incidentally, papillary fibroelastomas may embolize to cerebral circulation. Valvular locations are predominant; location in left atrium is rare. In this paper, we present a case of papillary fibroelastoma located in left atrium wi...

Backround. Thyroglossal duct cyst (TDC) is a developmental abnormality of the thyroid gland. Due to embryological remnants of thyroid tissue located in the TDC, the same malignant tumors that develop in the thyroid gland can also develop in the TDC. Methods. We present the unique case of a 39-year-old female with simultaneous de novo papillary carcinoma in a TDC and the thyroid gland. Results. ...

Background: Thyroid papillary carcinoma is the most common clinical thyroid malignancy. Autophagy is related to the occurrence and development of tumors. However, there is no report about the correlation between autophagy protein expression and biological characteristics of thyroid papillary carcinoma and lymph node metastasis. Therefore, the authors studied the relationship between autophagy p...
