We report the case of an 80-year-old man who presented with pathologically diagnosed chromophobe renal cell carcinoma composed of eosinophilic cells with partial papillary growth. The patient had a 2.5 cm diameter renal mass incidentally detected by abdominal ultrasound examination. Laparoscopic left partial nephrectomy was performed under a diagnosis of left renal tumor. Histopathology demonst...

OBJECTIVE To compare the cytophotometric quantitative expression of Ki-67 cellular proliferation factor in the colloid goiter with papillary carcinoma of the thyroid. METHODS The protein Ki-67 was studied with immunohistochemistry in 20 cases of papillary carcinoma of the thyroid and 12 cases of colloid goiter. The immunomarked cell nuclei were quantified through the software SAMBA 4000 and a...

 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 r...

This is the first report of papillary thyroid carcinoma combined with multiple endocrine neoplasia type 1 (MEN1) in Korea. MEN1 is a hereditary disease comprising neoplastic disorders such as pituitary, parathyroid and pancreatic neuroendocrine tumor, such as gastrinoma. But papillary thyroid cancer was never regarded as its component before in Korea. Herein we present a 39-year-old woman who m...

INTRODUCTION Papillary thyroid carcinoma and medullary thyroid carcinoma are two different thyroid neoplasia. The simultaneous occurrence of medullary thyroid carcinoma and papillary thyroid carcinoma as a collison tumor with metastases from both lesions in the regional lymph nodes is a rare phenomenon. CASE PRESENTATION A 32-year-old Iranian man presented with a fixed anterior neck mass. Ult...

Due to exponential growth and high diversity of DICOM images in healthcare industry, medical image mining has gained prominent attention because extraction of useful and effective patterns is one of the major problems in DICOM images. For instance, differentiating between the mimic, mix and complex patterns of thyroid papillary carcinoma (PTC) and other cancers in FNAC images is really challeng...

BACKGROUND The optimal course of clinical follow-up after a diagnosis of breast papillary lesion on a core needle biopsy (CNB) remains elusive. In particular, no reports in literature have addressed this question in African-American population. We describe our experience with breast papillary lesions in a primarily African-American population. METHODS A search of our database for breast papil...

Biliary (hepatic and extrahepatic) intraductal papillary mucinous neoplasms and intraductal oncocytic papillary neoplasms/carcinoma are rare neoplasms. Classification of biliary intraductal papillary tumors can be confusing and reports in radiology literature are extremely limited. We describe the first reported case of biliary intraductal oncocytic papillary neoplasms/carcinoma in the liver in...

A case of an isolated submandibular gland metastasis from a clinically occult papillary thyroid carcinoma is described in a 46-year old lady. Initial surgery was done based on the fine needle aspiration cytology (FNAC) report of adenocarcinoma of the submandibular gland. Histopathologic examination of the specimen suggested a metastatic papillary carcinoma. Occult papillary carcinoma in the thy...

UNLABELLED The aim of the present study was to present data on frequency of thyroid cancer in Mures County (Romania) and border counties, a goiter endemic area, and to analyze its histopathological characteristics, over a 20 years period (1990-2009). MATERIALS AND METHODS Demographic, clinical and pathological data were obtained from database registries. Histological subtypes of thyroid cance...
