Lobular carcinoma in situ (LCIS) clinically constitutes a risk factor for the subsequent development of either invasive lobular carcinoma (ILC) or invasive ductal carcinoma (IDC). In order to approach the possibility of this common precursor of both ILC and IDC, we investigated combined lobular and ductal carcinomas. Thirty-two cases of lobular carcinoma were picked up out of 773 cases of opera...
OBJECTIVES Earlier studies indicated that hamster pancreatic ductal adenocarcinoma not only derives from ductal/ductular structures but also from cells within the islet. So far unidentified cells within the islet are responsive to the carcinogenic effect of N-nitrosobis (2-oxopropyl) amine (BOP) forming poorly differentiated ductal adenocarcinoma. However, studies indicated a major role of β-ce...
CONTEXT There are few studies regarding the surveillance period and interval of resected or observed branch duct intraductal papillary mucinous neoplasms (IPMNs) of the pancreas in terms of early detection of concomitant pancreatic ductal adenocarcinoma. Despite a strict surveillance protocol, some patients are diagnosed with metastatic distinct ductal adenocarcinoma after resection of IPMN. ...
BACKGROUND To determine in a large series of surgical biopsies, the frequency of various histologic types of primary solid malignant neoplasms in males and females in different age groups. METHODS A retrospective study of 20,000 consecutive surgical biopsies reposted in the section of histopathology, AKU in 2004. RESULTS Malignant neoplasms are commonest in the fifth and sixth decades of li...
OBJECTIVE The main function of the breast is to produce milk for offspring. As such, the ductal system, which carries milk from the milk-secreting glands (alveoli) to the nipple, is central to the natural function of the breast. The ductal system is also the region in which many malignancies originate and spread. In this study, we aimed to assess the feasibility of manual mapping of ductal syst...
OBJECTIVE Foetal ductal problems may have various cardiopulmonary consequences. This study aimed to identify the spectrum of ductus arteriosus (DA) dysfunction (closure, constriction, kinking, aneurysm and thrombosis) and the resultant clinical and echocardiographic presentation in foetuses and neonates. METHODS AND RESULTS This is a retrospective analysis of serial pre- and post-natal data o...
Encapsulated papillary ductal carcinoma (EPC) of the breast is a rare form of cancer with defining histopathology of encapsulation. These lesions are typically indolent but may rarely have concomitant, synchronous invasive lesions.This report details a 56-year-old black female who presented with a palpable left breast mass. Adenosis with focal fibrous and ductal hyperplasia characteristics were...
