Pediatric Prostatic Alveolar Rhabdomyosarcoma Presenting with Metastatic Spinal Cord Compression in the Thoracic Spine: A Case Report and Review of the Literature.

Rhabdomyosarcoma (RMS) is a pediatric malignancy with a variable prognosis depending on tumor stage and genotype. There has been a significant improvement in survival rates over the past decades. However, aggressive variants can metastasize to locations that are difficult to treat.

Posttransplant lymphoproliferative disorder in a kidney transplant recipient: a case of Epstein-Barr virus-positive primary central nervous system lymphoma.

Posttransplant lymphoproliferative disorders (PTLDs) are potentially life-threatening complications of chronic immunosuppression in patients who receive solid organ transplants or allogeneic hematopoietic cell transplantation. Most PTLD cases are associated with Epstein-Barr virus (EBV) serology, and their incidence is typically higher in the first year of transplantation. Isolated EBV-positive diffuse large-cell B-cell lymphoma in the renal transplant setting has rarely been reported.

A Quantitative and Qualitative Assessment of Frozen Section Diagnosis Accuracy and Deferral Rate Across Organ Systems.

Objectives: Monitoring of frozen section diagnostic performance provides an important quality improvement measure.

Methods: Surgical specimens involving a frozen section diagnosis over a 3-year period were retrospectively reviewed. Glass slides were reviewed on cases with discordance.
