Coexistence of Pancreatic Neuroendocrine Tumor and Pseudotumor: Two Rare Lesions.

Neuroendocrine tumors and pseudotumors of the pancreas are 2 separate rare lesions. Neuroendocrine tumors originate from neuroendocrine cells, but many different factors have been suggested for the origin of pseudotumors. As the first reports of these 2 distinct entities found in a single patient have been published, our aim is to present the imaging and pathological characteristics of these entities.

Pseudoangiomatous stromal hyperplasia (PASH) of the breast: intraductal appearance.

Pseudoangiomatous stromal hyperplasia (PASH) is a benign proliferative lesion of breast stroma. The diagnosis of PASH can be made using imaging techniques such as ultrasound, magnetic resonance or mammography. Ductoscopy is a relatively new technique which is used for imaging the intraductal surface.

Independent Predictors of Treatment Modality for Penetrating Colon Injury.

Background And Aims: We aimed to evaluate the independent factors of the treatment of penetrating colon injuries in a teaching and research hospital in light of some of the most commonly cited considerations affecting the decision as to whether to perform primary repair or divert.

Methods: Hospital records of patients between January 2004 and January 2007 were reviewed retrospectively. Fifty-seven patients were included and divided into two groups.

Can nomograms predict non-sentinel lymph node metastasis after neoadjuvant chemotherapy in sentinel lymph node-positive breast cancer patients?

Background: The predictive probability of breast cancer nomograms for non-sentinel node metastases (NSLNM) after neoadjuvant chemotherapy (NCT) in patients with a positive sentinel lymph node (SLN) biopsy is unknown. The aim of this study was to evaluate the accuracy of 3 different nomograms in patients receiving NCT.

Patients And Methods: Between 1999 and 2007, 54 patients presented with clinically N0 disease received NCT.

Predicting likelihood of having four or more positive nodes in patient with sentinel lymph node-positive breast cancer: a nomogram validation study.

Purpose: Katz suggested a nomogram for predicting having four or more positive nodes in sentinel lymph node (SLN)-positive breast cancer patients. The findings from this formula might influence adjuvant radiotherapy decisions. Our goal was to validate the accuracy of the Katz nomogram.

Predictive probability of four different breast cancer nomograms for nonsentinel axillary lymph node metastasis in positive sentinel node biopsy.

Background: Although completion axillary lymph node dissection (CALND) is the gold standard for evaluating axillary status after identification of a positive sentinel lymph node (SLN) in breast cancer, almost 40% to 70% of SLN-positive patients will have negative non-SLNs. To predict non-SLN metastases (NSLNM) in patients with a positive SLN biopsy, four different nomograms have been created. The aim of this study was to evaluate the accuracy of four different nomograms in our SLN-positive breast cancer patients.
