Mucinous tubular and spindle cell carcinoma (MTSCC) is a relatively rare renal epithelial neoplasm. Although MTSCC is considered to be a low-grade and indolent neoplasm, aggressive cases have been recently reported. The present study discussed two additional cases of high-grade MTSCC causing multiple distant metastases with a fatal course.

Prediction of subsequent risks of breast carcinoma (BC) development in intraductal papilloma (IDP) has remained controversial with the exception of atypical papilloma (AP). The potential value of immunohistochemistry (IHC) of cytokeratin 5/6 [CK5/6] and p63 have been proposed but its standardization has also remained controversial. We studied 17 patients initially diagnosed as IDP or AP who subsequently developed BC with 34 age-matched controls.

Atypical ductal proliferation or ADP has been used in histopathological diagnosis of core needle biopsy (CNB) but its details have not been well studied. Therefore, we examined the clinicopathological characteristics of the initial CNB cases diagnosed as 'ADP ' who subsequently turned out to be malignant, and compared the findings to those that did not. Among 101 cases initially diagnosed as ADP in CNB, the second biopsy revealed no carcinoma (38), ductal carcinoma in situ (DCIS) (45) and invasive carcinoma (18).

Objective: Anatomic properties of myocardial bridge (MB) are sometimes responsible for myocardial infarction (MI) through the changes in the atherosclerosis distribution in the left ascending coronary artery (LAD). The purpose of this study was to investigate histopathologic profiles of atherosclerotic lesions resulting from the MB presence in the LAD in the MI cases.

Methods: In 150 consecutive autopsied MI hearts either with MBs [MI(+)MB(+); n = 67] or without MBs [MI(+)MB(-); n = 83] and 100 normal hearts with MBs [MI(-)MB(+)], LADs were consecutively cross-sectioned at 5-mm intervals.
