PURPOSE The aim of this study was to evaluate the tissue stiffness of solid pancreatic lesions by using acoustic radiation force impulse (ARFI) elastography to differentiate benign from malignant pancreatic lesions. METHODS ARFI elastography was performed in 26 patients who had 27 focal solid pancreatic lesions, including 8 benign lesions (mass-forming pancreatitis, 5; autoimmune pancreatitis...

PURPOSE To evaluate fast 3D near-infrared breast imaging using the optical contrast agent indocyanine green (ICG) for the detection and characterization of breast lesions. MATERIALS AND METHODS 30 patients with suspicious breast lesions on mammography and/or ultrasound underwent fast 2 Hz 3D optical mammography before, during, and after administration of a 25 mg ICG bolus prior to needle biop...

BACKGROUND AND AIMS To assess the expression levels of cathepsins in malignant and premalignant lesions. METHODS We retrospectively included patients who underwent pancreatic surgery on pancreatic solid or cystic masses. The expression of cathepsin H, L, B and S was determined in both types of samples. Lesions were divided into three categories: malignant (pancreatic adenocarcinoma and malign...

Zosteriform metastasis is a rare clinical distribution from spreading neoplasms of every organ to the skin. Tumors most often arise from a n internal o r hematologic malignancy. W e report a 69-year-old man, a known case of malignant melanoma of the left heel. In this case, multiple red-brown metastatic nodules appeared four months after diagnosis.

Abstract Skin cancer arises from the skin and is capable of invading other parts body. The earlier detection malignant lesions effectively helps cure disease prevents fatal cancer. As part AI, machine learning deep can learn characteristics input datasets perform classifications with high accuracy. In this paper, CNN, KNN, SVM models are implemented tested based on collected ISIC. idea implemen...

PURPOSE To investigate the utility of opposed-phase magnetic resonance imaging (OP MRI) in differentiating malignant from benign bone lesions. MATERIALS AND METHODS MRI scans of musculoskeletal lesions including opposed-phase imaging sequences were reviewed by both an experienced musculoskeletal attending radiologist, and a second year radiology resident. The change in signal from IP to OP im...

Although gastrointestinal involvement by metastatic malignant melanoma is common but primary gastrointestinal (GI) melanoma has been reported in rare cases. In this study we report two cases of primary gastrointestinal malignant melanoma that one of them is a known case of neurofibromatosis type 1(NF1). Both cases showed no evidence of any lesions in skin and eye. Malignant melanoma of GI tract...

Association of lichen planus and cutaneous malignancies is rare. Reports of neoplastic changes are mostly related to buccal chronic erosive lichen planus. We report herein a 29-year-old man who developed squamous cell carcinoma on previous lesions of chronic hypertrophic lichen planus of lower legs. Careful follow up of patients with chronic lichen planus and biopsy sampling of uncommon lesions...
