PURPOSE To identify the CT and MR characteristics of craniopharyngiomas, to evaluate the histologic types of craniopharyngioma, and to compare the radiologic/histologic appearance and type of therapy with tumor recurrence. METHODS We reviewed the records of 45 patients with craniopharyngiomas for which surgical specimens (n = 45), preoperative MR or CT studies (n = 27), or other MR or CT stud...

BACKGROUND The most frequent form of inflammatory bowel disease (IBD) in dogs is represented histologically, by lymphoplasmacytic enteritis (LPE), a histological category, often associated with other morphologic alterations including lymphangiectasia (LE). However, literature data on this latter topic are quite scarce and have mostly been obtained in single reports or in small series. AIM We ...

INTRODUCTION Pulmonary arteriovenous malformations are a common cause of progressive cyanosis in children after cavopulmonary anastomoses. We analyzed the pulmonary histologic characteristics from children in whom pulmonary arteriovenous malformations developed after procedures that resulted in pulmonary arterial blood flow devoid of hepatic venous effluent. METHODS We performed routine histo...

BACKGROUND Helicobacter pylori (H. pylori) has been considered a definitive carcinogen in gastric cancer. Telomerase is activated in gastric cancer and some premalignant gastric lesions, including intestinal metaplasia (IM). In this study, we evaluated the relationships of both H. pylori infection and telomerase activity with endoscopic and histologic features in IM. The effects of H. pylori er...

PURPOSE Mucinous adenocarcinomas account for about 10% of all colorectal cancers. This study aimed to investigate the prognostic impact of mucinous histologic subtype on oncologic outcomes in patients with colorectal cancer. METHODS This retrospective study was performed at two large tertiary university hospitals. We analyzed the characteristics, prognostic factors, and survival of patients w...

Multiple or second primary lung cancers can develop at any sites in the lung with same or different histologic types, synchronously and/or metachronously. In case of metachronous occurrence of the second primary lung cancer, it is easy to confuse with the primary lung cancer as a recurrence of precedent lung malignancy treated successfully or metastasis. Previous reports have demonstrated that ...

OBJECTIVE To determine the utility of confocal scanning laser microscopy (CSLM) in the in vivo evaluation of congenital melanocytic nevi (CMNs) that are suggestive of having developed melanoma. DESIGN The CMNs suggestive of melanoma by clinical and dermoscopic examination were imaged by CSLM, and the findings correlated with the features seen on dermoscopic and histologic examination. SETTI...

To determine the changes in histologic features during the course of prostate cancer under long-term endocrine therapy, histologic grade and argyrophilic nucleolar organizer regions (AgNORs) were examined in specimens before treatment, at relapse, and at cancer death. A total of 29 patients who had received therapy and died of prostate cancer were evaluated. Among the 29 cases, biopsy tissues b...
