the basic pathogenic step in the process of tumor growth, invasion and metastasis is tumor-induced angiogenesis. the aim of this study was to evaluate the angiogenesis in colorectal carcinoma by microvascular density (mvd) determination with ihc (immunohistochemistry) method and to determine if and how angiogenesis correlates with clinicopathologic parameters. sixty two archival, paraffin embed...
OBJECTIVE To define the clinicopathologic features of eyelid involvement in Melkersson-Rosenthal syndrome (MRS). METHODS Four patients with eyelid edema consistent with MRS were evaluated clinically, including diagnostic imaging in 2 patients. Eyelid tissue from these patients was examined by light microscopy and immunohistochemistry. Polymerase chain reaction for herpes simplex virus was per...
Gorlin-Goltz syndrome, also known as nevoid basal cell carcicoma syndrome, comes into being due to a genetic alteration produced by a mutation in the "Patched" tumour suppressor gene, and it is inherited in a dominant autosomal way, though sporadic cases have been found. This syndrome shows a high penetrance and variable expressiveness. It is about a multisystemic process that is characterised ...
● Context.—Birt-Hogg-Dubé (BHD) syndrome is a rare clinicopathologic condition transmitted in an autosomal dominant fashion. This complex entity is characterized by cutaneous fibrofolliculomas, kidney tumors, pulmonary cysts, and spontaneous pneumothorax. Recently, the gene possibly responsible for the clinical manifestations of BHD syndrome has been cloned and characterized. The few reviews of...
Scintigraphic, clinical and pathological findings were correlated in 52 patients studied by technetium-99m stannous pyrophosphate ("mTc-PYP) myocardial scintigraphy before death or surgical resection of myocardium. Fifty-nine clinical events were studied with scintigraphy in the 52 patients; 41 of the 59 were associated with one or more abnormal "mTc-PYP studies and 18 with normal 9OmTc-PYP sci...
IMPORTANCE Mutations in the gene encoding parkin (PARK2) are the most common cause of autosomal recessive juvenile-onset and young-onset parkinsonism. The few available detailed neuropathologic reports suggest that homozygous and compound heterozygous parkin mutations are characterized by severe substantia nigra pars compacta neuronal loss. OBJECTIVE To investigate whether parkin-linked parki...
BACKGROUND Combined hepatocellular and cholangiocarcinoma (CHC) is a unique subtype of liver cancer comprising both hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC); however, its cellular origin remains unclear. The purpose of this study was to investigate the clinicopathologic features and the clonal relationship between HCC and ICC in 34 patients with CHC. METHODS Th...
هدف: این مطالعه به منظور بررسی فراوانی ناهنجاری های مغزی – نخاعی در بیماران دچار اسکولیوز ایدیوپاتیک اطفال و نوجوانان انجام شده است.روش مطالعه: این مطالعه به صورت یک بررسی توصیفی - تحلیلی مقطعی انجام شده است. حجم نمونه مورد بررسی در این مطالعه شامل 232 کودک مبتلا به اسکولیوز ایدیوپاتیک مراجعه کننده به بیمارستان طالقانی تهران طی سال های 86 تا 88 بود که به صورت سرشماری انتخاب گردیده بودند.یافته ه...
Abstract Objectives We compared the clinicopathologic features, clinical management, and outcomes of human epidermal growth factor receptor 2 (HER2)–expressing nonexpressing microinvasive breast carcinomas (MiBC) to explore significance HER2 in MiBC. Methods Clinicopathologic follow-up information cases with final diagnosis MiBC known status between 2007 2019 were analyzed. Results Nineteen (41...
