The aim of the present study was to investigate chromosomal aberrations in sporadic Japanese papillary thyroid carcinomas (PTCs), concomitant with the analysis of oncogene mutational status. Twenty-five PTCs (11 with BRAF(V600E), 4 with RET/PTC1, and 10 without mutation in HRAS, KRAS, NRAS, BRAF, RET/PTC1, or RET/PTC3) were analyzed using Genome-Wide Human(More)
Splenic cyst is a relatively rare disease; however, the occurrence of complications associated with its rupture is even more rare. A 20-year-old female patient who had severe abdominal and left shoulder pain was admitted to our hospital. The patient's abdomen was hard and tender to the touch and she presented with a high fever. The patient's serum levels of(More)
INTRODUCTION Recurrent rectal prolapse is an unresolved problem and the optimal treatment is debated. This study was designed to review patterns of care and outcomes in a large cohort of patients after surgery for recurrent prolapse. METHODS From 685 patients who underwent operative repair for full-thickness external rectal prolapse, we identified 78(More)
We evaluated the associations between tumor-infiltrating lymphocytes (TIL) including CD8-positive [+] lymphocytes in ductal carcinoma in situ (DCIS) and histopathologic factors, particularly spontaneous "healing" and immunohistochemical (IHC)-based subtypes, to clarify the effects of host immune response to cancer cells proliferation during early(More)
An 85-year-old male with advanced squamous cell carcinoma of the lung, who was diagnosed about 10 years prior to his current presentation, suddenly complained of abdominal pain and underwent an abdominal computed tomography scan, which revealed free air and massive ascites. He was admitted to our hospital for acute peritonitis and emergency surgery was(More)
Plasmablastic lymphoma (PBL) is a rare form of non-Hodgkin's lymphoma that is associated with human immunodeficiency virus (HIV) infection. Although PBL is most commonly observed in the oral cavity of HIV-positive patients, it can also be observed at extra-oral sites in HIV-negative patients. This report represents an unusual case of HIV-negative PBL that(More)
The aim of this study was to evaluate the chronological changes in the amount of drainage fluid after thyroidectomy, and to establish standard indications for the drain to be removed. We examined a cohort of 249 patients undergoing thyroid surgery. The patients were divided into four groups: a Graves’ group, a non-dissection group, a central-dissection(More)
Parenchymal leiomyomas of the breast are extremely rare, with only 25 cases reported in the literature. We report the 26th case of parenchymal leiomyoma of the breast in a 63-year-old woman who presented to us with a right breast tumor detected on her screening mammography. This tumor was evaluated by mammography, ultrasonography, and MR imaging. To the(More)
BACKGROUND Several single nucleotide polymorphisms (SNP) have been identified to be associated with the risk for differentiated thyroid cancer in populations of distinct ethnic background. The relationship of these genetic markers to a benign tumor of the thyroid, follicular adenoma (FA), is not well established. METHODS In a multicenter retrospective(More)
BACKGROUND/AIMS We investigated whether the serum Thymidine phosphorylase (TP) levels in venous blood drainage specimens were associated with the prognosis and risk of liver metastasis in patients with resectable colorectal cancer. METHODOLOGY From 88 patients with colorectal cancer, specimens of venous blood drainage were obtained during operation. The(More)
