Peliosis hepatis disseminated rapidly throughout the liver in a patient with prostate cancer: a case report.

Introduction: In the World Health Organization histological classification of the liver tumor, peliosis hepatis is defined as a tumor-like lesion. The entity is characterized by the appearance of multiple cyst-like, blood-filled spaces within the liver parenchyma.

Case Presentation: A 77-year-old Japanese man with prostate cancer was referred to our department because he was diagnosed as having two hepatic tumors.

Clinical value of dividing false positive urine cytology findings into three categories: atypical, indeterminate, and suspicious of malignancy.

Background: The aim of this study was to evaluate 10 years of false positive urine cytology records, along with follow-up histologic and cytologic data, to determine the significance of suspicious urine cytology findings.

Materials And Methods: We retrospectively reviewed records of urine samples harvested between January 2002 and December 2012 from voided and catheterized urine from the bladder. Among the 21,283 urine samples obtained during this period, we located 1,090 eligible false positive findings for patients being evaluated for the purpose of confirming urothelial carcinoma (UC).

Co-registered positron emission tomography/computed tomography and gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid magnetic resonance imaging features of multiple angiosarcoma of the liver.

Hepatic angiosarcoma is a very rare disease, accounting for only 2% of primary liver malignancy. An 82-year-old man was admitted to our hospital because of jaundice and weight loss. Computed tomography (CT) and magnetic resonance imaging (MRI) showed diffuse and multiple space-occupying lesions.

Comparative image analysis of conventional and thin-layer preparations in endometrial cytology.

We evaluated the differences in cytologic findings between conventional and thin-layer preparations in endometrial cytology to introduce the thin-layer method into routine cytology. Eighty patients who had undergone endometrial cytology and biopsy on the same day were selected and we compared the cytological findings between conventional- and thin-layer preparations (TLP) in endometrial cytology. The numbers of neutrophils and cell clusters in the thin-layer method were lower than those in the conventional smear (CSS) method.

A case of cholestatic hepatitis associated with histologic features of acute cholangitis.

This report describes a case showing histologic features of acute cholangitis with an over-the-counter drug. A 48-year-old woman was diagnosed with general malaise and progressive jaundice.
