Congenital and acquired abnormalities of the reproductive tract of female sheep resulting in subfertility,infertility or sterility cannot easily be detected by routine clinical examination. Morphopathologicalabnormalities of the reproductive tract of ewes were studied by examining a total of 739 genital tracts inabattoirs of Fars province, Iran. From these, the 648 non-pregnant genitalia were e...

BACKGROUND Intravascular papillary endothelial hyperplasia (IPEH) is a benign intravascular process with features mimicking other benign and malignant vascular proliferations. IPEH lesions predominate in the head-neck region and the extremities. The characteristic histomorphological feature of IPEH is a papillary structure covered with hyperplastic endothelial cells within the vascular lumen. I...

To examine the pathogenesis of intravascular papillary endothelial hyperplasia (IPEH), a relatively uncommon benign, non-neoplastic vascular lesion, clinicopathological and immunohistochemical studies were performed. Paraffin-embedded tissue specimens of 78 vascular lesions were examined histologically, and 9 cases of IPEH were investigated immunohistochemically using antibodies against CD34, v...

Oral Verrucous Lesions (OVL) comprise of Hyperplasia (VH), Keratosis, Proliferative Leukoplakia (PVL) and Carcinoma Cavity (VC) known as Ackermann’s Tumour. These predominantly emerge slow proliferating, gray or white, warty, exophytic lesion with micro-nodular surface & commonly seen on the buccal, labial mucosa, gingiva, tongue palate. are associated consumption tobacco in smoke smokeless...

K-ra.v oncogene mutation has been shown to be a frequent event in pancreatic ductal adenocarcinomas induced by the carcinogen V-nitroso-bis(2-oxopropyl)amine in the hamster. The present study exam ines the mutational status of the K-r«.v oncogene in lesions that precede the appearance of invasive ductal adenocarcinomas. Syrian golden ham sters (80-100 g) received 12 weekly doses of 15 mg/kg A'...

OBJECTIVE: To demonstrate the most frequent features of cystic breast lesions at ultrasound elastography, discussing the applicability of this method. MATERIALS AND METHODS: The present casuistic included 150 patients referred for percutaneous breast biopsy of 175 lesions. Histologically diagnosed solid lesions (153 lesions) were excluded; lesions histologically diagnosed as cystic (22 lesions)...
