Salivary gland tumors accounts for less than 1% of all tumors. Minor salivary gland tumors (MSGTs) are uncommon and make up about 10% of all salivary gland neoplasms. The clinical and histopathological distribution of these tumors vary geographically. A case of a 38 yr old man with a minor salivary gland mass at chin region isreported here. The tumor invaded into the anterior ...
Liposarcoma is a common malignant soft tissue tumor, accounting for 10% to 16% of all sarcomas. Multicentric myxoid liposarcoma is an uncommon condition. Differentiation between several primary tumors and metastasis of a single liposarcoma represents the main difficulty in diagnosis. A 47-years old woman presented with right thigh myxoid liposarcoma and underwent wide margin tumor resection. ...
BACKGROUND O-(2-18 F-fluoroethyl)-L-tyrosine-(FET)-PET may be helpful to improve the definition of radiation target volumes in glioblastomas compared with MRI. We analyzed the relapse patterns in FET-PET after a FET- and MRI-based integrated-boost intensity-modulated radiotherapy (IMRT) of glioblastomas to perform an optimized target volume definition. METHODS A relapse pattern analysis was p...
Received January 13, 2007; accepted March 4, 2007. OBJECTIVE To investigate the factors that can accurately predict the prognosis for patients with FIGO stage-IB cervical squamous cell carcinoma treated with radical surgery. METHODS A retrospective analysis of clinical data from 174 cases of FIGO Stage-IB cervical squamous cell carcinoma treated in our institute was conducted. RESULTS The 5-yea...
Osteosarcoma around the knee treated with neoadjuvant chemotherapy and a custom-designed prosthesis.
This article describes a novel approach using high-dose neoadjuvant chemotherapy with wide tissue resection and a specially designed artificial joint in 104 patients with stage IIB osteosarcoma near the knee. Sixty-four lesions were located at the distal femur, 39 at the proximal tibia, and 1 invaded the proximal tibia from the distal femur. Pathological fracture was present in 9 patients. Thre...
Histopathologic margin distance in survival in resection of cutaneous melanoma of the head and neck.
OBJECTIVES/HYPOTHESIS Treatment of cutaneous melanoma involves surgical excision with wide clinical margins. No guidelines regarding safe histopathologic margin distance exist. This study examines the impact of histopathologic margin, measured from closest cut edge of the specimen, on overall survival in resection of cutaneous melanoma of the head and neck. We hypothesize that close histopathol...
We report a case of primary gastric carcinoma with a macroscopic appearance indistinguishable from that of a submucosal tumor. A 48-year-old man visited our hospital with a chief complaint of epigastric discomfort. Endoscopic examination revealed a protruding lesion with a well defined margin on the anterior wall of the gastric antrum. Most of the tumor surface was covered with apparently norma...
OBJECTIVE The purpose of this study was to determine the utility of preoperative CT in predicting early recurrence of hepatocellular carcinoma after partial hepatic resection. MATERIALS AND METHODS Preoperative three-phase helical CT scans in 53 patients with hepatocellular carcinoma were retrospectively reviewed by two radiologists. In 27 patients (group I), HCC had recurred within six month...
Pancreatic ductal adenocarcinoma (PDAC) is characterized by a strong fibrotic stromal reaction and diffuse growth pattern. Peritumoral fibrosis is often evident during surgery but only distinguishable from tumor by microscopic examination. The aim of this study was to investigate the role of clearance of fibrotic stromal reaction at the mesopancreatic resection margin as a criterion for radical...
Two consecutive surveys for breast surgeons in Korea were conducted to comprehend the practice patterns and perceptions on margin status after breast-conserving surgery. The surveys were conducted online in 2014 (initial) and 2016 (follow-up). A total of 126 and 88 responses were obtained in the initial and follow-up survey, respectively. More than 80% of the respondents replied to routinely ap...
