Assessment of whole-body MRI including diffusion-weighted sequences in the initial staging of breast cancer patients at high risk of metastases in comparison with PET-CT: a prospective cohort study.

Objective: The aim of this study was to assess the diffusion-weighted whole-body-MRI (WBMRI) in the initial staging of breast cancer at high risk of metastases in comparison with positron emission tomography (PET)-CT.

Methods: Forty-five women were prospectively enrolled. The inclusion criteria were female gender, age >18, invasive breast cancer, an initial PET-CT, and a performance status of 0-2.

Interpretive Errors in Fine-Needle Aspiration of Thyroid: A 13-Year Institutional Experience in Lebanon.

Introduction: Fine-needle aspiration (FNA) is a worldwide established diagnostic tool for the assessment of patients with thyroid nodules. All thyroid FNA interpretive errors (IEs) were reviewed at the American University of Beirut Medical Center over a 13-year period, in order to identify and analyze them.

Materials And Methods: All FNAs and their corresponding pathology results are correlated yearly for quality assurance.

Primary vulvar Ewing sarcoma/peripheral primitive neuroectodermal tumor with pelvic lymph nodes metastasis: A case report and review of literature.

Ewing sarcoma (ES) and peripheral primitive neuroectodermal tumors (pPNET) are soft tissue tumors that generally affect the bones. Extraosseous ES/pPNET has been rarely reported. Our patient presented with a 6 × 4 cm right subcutaneous solid vulvar lesion causing pain and discomfort.

Malignant melanoma with metaplastic cartilaginous transdifferentiation: A case report.

Malignant melanoma is notorious for its remarkable morphological variation and aberrant histopathological patterns. However, melanoma with prominent cartilaginous transdifferentiation simulating chondrosarcoma is extremely rare. A 75-year-old male developed a swelling in his left inguinal region and was diagnosed with a metastatic melanoma, which was found to harbor a BRAF V600E mutation.
