Irregular medullary cavity Normal Renal Papillary Necrosis – Medullary Form FIGURE 6-36 Schematic of the progressive stages of the papillary form of renal papillary necrosis and their associated radiologic changes seen on intravenous pyelography. Papillary necrosis occurs in one of two forms. In the medullary form, also termed partial papillary necrosis, the inner medulla is affected; however, ...

hashimoto’s thyroiditis is associated with an increased risk of developing papillary carcinoma of thyroid. we hereby report a case of hashimoto’s thyroiditis with papillary carcinoma in a 45-year-old ear old female diagnosed on fine needle aspiration cytology (fnac) which was later confirmed on histopathological examination .such an occurrence, when both lesions are picked up on fnac in a patie...

INTRODUCTION Galectin family members have been demonstrated to be abnormally expressed in cancer at the protein and mRNA level. This study investigated the levels of galectin proteins and mRNA expression in a large cohort of patients with papillary thyroid carcinoma and matched lymph node metastases with particular emphasis on galectin-1 and galectin-3. METHODS mRNA expression of galectin fam...

Mutation of the BRAF gene is common in thyroid cancer. Follicular variant of papillary thyroid carcinoma is a variant of papillary thyroid carcinoma that has created continuous diagnostic controversies among pathologists. The aims of this study are to (1) investigate whether follicular variant of papillary thyroid carcinoma has a different pattern of BRAF mutation than conventional papillary th...

During ischemia, lidocaine or quinidine may prevent arrhythmias by blocking conduction without suppressing abnormal automaticity. The purpose of this study was to determine whether lidocaine or quinidine (5 micrograms/ml) produced Purkinje fiber-papillary muscle block during superfusion in vitro with an altered Tyrode's solution containing some components of ischemia: 6 mM potassium, PO2 less t...

BACKGROUND/AIMS CD44s, the standard form of CD44, has been shown to be downregulated during malignant transformation of breast cancers. It has also been reported recently to be a useful marker in differentiating between benign and malignant papillary lesions of the breast, with high expression in the former. CD44s expression in benign and malignant papillary lesions was evaluated. METHODS CD4...

BACKGROUND The aim of this study was to observe the rotation patterns at the papillary muscle plane in the Left Ventricle(LV) with normal subjects using two-dimensional speckle tracking imaging(2D-STI). METHODS We acquired standard of the basal, the papillary muscle and the apical short-axis images of the LV in 64 subjects to estimate the LV rotation motion by 2D-STI. The rotational degrees a...

thyroglossal duct cysts are the most common congenital anomalies in thyroid development, which in less than 1% of cases are malignant. in most cases the diagnosis is made postoperatively. up to now, a few cases have been reported which had been papillary carcinoma. controversies exist concerning its nature and treatment. we present a 30 years old woman with papillary carcinoma of thyroglossal d...

malignant papillary neoplasms of the breast comprise a number of microscopically distinct lesions, where apocrine metaplasia is commonly found in papillomas compared to other papillary lesions including papillary carcinomas. however, association of apocrine metaplasia in papilloma with ductal carcinoma in situ (dcis) is not very well defined. the lesions with apocrine metaplasia are not only di...
