Two Cases of Penile Cancer: Magnetic Resonance Imaging in the Evaluation of Tumor Extension

Two patients with penile cancer were evaluated with magnetic resonance imaging (MRI) to determine tumor extent. Corporeal involvement was revealed in only 1 of the 2 cases, which was delineated on MRI and confirmed histologically. We conclude that MRI, especially the T1-weighted image, is helpful in determining treatment in cases of penile cancer.

Leuprorelin acetate blood levels and dialysance after the administration of sustained-release leuprorelin acetate in a dialysis case complicated by prostate cancer

The objective of this study is to determine whether in a dialysis patient with prostate cancer leuprorelin acetate blood levels were abnormally high or low due to kidney failure or because of dialysis.

Malignant fibrous histiocytoma of the right spermatic cord: a case report.

Abstract The patient was a 47‐year‐old male, who visited Hidaka Hospital with a chief complaint of swelling in the right inguinal region and the scrotum. With a diagnosis of a right spermatic cord tumor, right high orchiectomy was performed. Since an inflammatory type of malignant fibrous histiocytoma (MFH) was diagnosed from histopathological findings, chemotherapy and radiation therapy were performed as postoperative treatment. Malignant fibrous histiocytoma with the primary focus of the spermatic cords is a rare disease. To our knowledge, this is the 20th case of MFH of the spermatic cord in Japan (the 42nd in the world) and it is the second case of inflammatory type of MFH in Japan.

Biochemical and Immunohistochemical Demonstration of Metallothionein in the Rat Prostate

Metallothionein in the rat prostate was demonstrated by using an indirect immunoperoxidase technique. Strong staining was found mainly in the supranuclear area of the cytoplasm of the glandular epithelium in the dorsal and the lateral glands. Diffuse cytoplasmic staining and nuclear staining were found with less frequency. Secretory granules were found in the lumen with various intensities of staining. Most of the epithelial cells in the ventral lobes and the coagulating glands were negatively stained. Immunoreactive cells were found sporadically. Two types of immunoreactive cells, round cells and spindle-shaped cells, were scattered in the stroma. Vascular endothelial cells, red blood cells, and smooth muscle cells were negatively stained. These results suggest the synthesis and secretion of metallothionein in the rat prostate.
