BACKGROUND AND OBJECTIVES Phyllodes tumors (PTs) are uncommon biphasic breast tumors that usually occur in adult females. They are composed of a benign epithelial component and a cellular, spindle cell stroma forming a leaf-like structure. No one morphologic finding is reliable in predicting the clinical behavior of the tumor. The purpose of this study was(More)
AIM To compare the efficacy and toxicity of a three-step combination therapy with post-operative radiation alone for locally advanced esophageal cancer. METHODS Patients with T3-4 and N0-1 esophageal carcinoma from a number of institutions were non-randomly, prospectively enrolled in the study. All patients underwent single-stage curative en bloc(More)
The aim of this study is to estimate the incidence of the gastrointestinal stromal tumor after the previous diagnoses were confirmed and/or revised by both immunohistochemical and mutational analyses. We reviewed 17,858 surgically excised gastrointestinal lesions in our hospital from 1998 to 2004. All mesenchymal tumors were examined for CD117 expression by(More)
We report 2 cases of Aspergillus pseudomembranous tracheobronchitis in patients with diabetes. The first patient succumbed to progressive obstructive respiratory failure despite mechanical ventilation and antifungal therapy. However, the second patient survived. Aspergillus tracheobronchitis should be considered in immuno-compromised patients presenting(More)
Renal angiomyolipoma (AML) is a benign tumor composed of fat cells, smooth muscle cells, and thick-wall blood vessels. Epithelioid angiomyolipoma (EAML) is a variant of AML and is composed of purely epithelioid cell with melanogenesis markers. Neither adipocytes nor abnormal blood vessels are noted. Pathologically, tumor cells have nuclear atypia and(More)
Growth differentiation factor-10 (GDF10), commonly referred as BMP3b, is a member of the transforming growth factor-β (TGF-β) superfamily. GDF10/BMP3b has been considered as a tumor suppressor, however, little is known about the molecular mechanism of its roles in tumor suppression in oral cancer. Clinical significance of GDF10 downregulation in oral(More)
The purpose of this study was to evaluate the presence of the hyperdense appendix in acute appendicitis. The CT scans of 183 patients with pathologically proven acute appendicitis were reviewed to determine the prevalence of a hyperdense appendix, defined as a high-attenuated appendix when compared with the adjacent cecal wall on precontrast CT. A control(More)
The likelihood of thyroid cancer is similar in patients with one or more nodules, but tumor characteristics of thyroid cancer in glands with multinodular goiter are unclear. This study consisted of 100 consecutive patients (ages 15–81 years; 84 women), who underwent thyroidectomy for papillary or follicular thyroid carcinoma between 2005 and 2006. Patient(More)
