The aim of this study was to compare the rate of incomplete resection and treatment outcome of the second-pass technique with those of single-pass technique in loop electrosurgical excisional procedure (LEEP). From 1997 to 2002, 683 women were diagnosed as squamous dysplasia via LEEP in our institution. Age, parity, LEEP technique, grade of lesion, glandular extension, margin status, residual t...

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 surf...

Dermatofibrosarcoma protuberans (DFSP) is an unusual spindle cell tumor with a high rate of local recurrence with traditional excision. Fortunately, Mohs micrographic surgery yields excellent cure rates for this neoplasm due to contiguous tumor spread and meticulous tumor mapping and margin analysis. We present the unique case of a patient treated with a modified Mohs technique with an analysis...

Laparoscopic wedge resection of gastric submucosal tumors is an established method, but the tumor is usually resected to an excessive extent [1,2]. Hiki et al. first reported laparoscopic-endoscopic cooperative surgery (LECS) for gastric tumors [3]. Under the LECS approach, the tumor can be resected with minimal but adequate surgical margin. We reported LECS for duodenal lesions in 2010 [4], bu...

Two adult patients with brainstem glioma were successfully treated surgically. A 37-year-old male had a dorsally exophytic pontine glioma developing from the fourth ventricular fundus, and another 27year-old male an intrinsic nodular mesencephalic glioma. Preoperative magnetic resonance imaging clearly visualized the tumor margin in both cases, and showed the relationship between the tumor and ...

Report of Cases. Case 1. A 9-yearold white girl underwent excision of a small, rapidly growing, black pigmented lesion of the inferior palpebral conjunctiva and the adjacent margin of the right lower eyelid. The original histopathologic diagnosis was an active junctional nevus of the conjunctiva and eyelid margin. The lesion recurred 3 years later and was excised by a dermatologist who did not ...

OBJECTIVES To identify risk factors for metastatic disease on histopathologic specimens of enucleated eyes from patients with unilateral retinoblastoma, and to evaluate the value of chemoprophylaxis in preventing disease dissemination. METHODS Medical records from patients with unilateral retinoblastoma who underwent primary enucleation were reviewed at the University of California, San Franc...

BACKGROUND To evaluate pancreatic tumor motion and its dynamics during respiration. METHODS AND MATERIALS This retrospective study includes 20 patients with unresectable pancreatic cancer who were treated with stereotactic ablative radiotherapy. An online respiratory tumor tracking system was used. Periodical maximum and minimum tumor positions with respiration in superior-inferior (SI), late...

OBJECTIVES The surgical margin status after radical prostatectomy for prostate cancer has long been considered a powerful prognostic factor, as well as an important risk factor for local recurrent disease after radical prostatectomy. In this study, a critical analysis of the predictive value of the surgical margin status was performed. METHODS A well-described cohort of 281 participants of a ...

OBJECTIVE To test the hypothesis that a safety margin may affect local tumor recurrence (LTR) in subsegmental chemoembolization. MATERIALS AND METHODS In 101 patients with 128 hepatocellular carcinoma (HCC) nodules (1-3 cm in size and ≤ 3 in number), cone-beam CT-assisted subsegmental lipiodol chemoembolization was performed. Immediately thereafter, a non-contrast thin-section CT image was ob...
