Invasive mucormycosis in a tertiary care hospital in the western region of Saudi Arabia: 11-year retrospective chart review from 2009 to 2019.

Background: Mucormycosis is a life-threatening, invasive fungal disease that mostly affects immunocompromised hosts. In this study, we aimed to assess the clinical presentations and outcomes of patients with mucormycosis in a tertiary care hospital in the western region of Saudi Arabia.

Methods: A retrospective chart review of patients diagnosed with mucormycosis was conducted from January 2009 to December 2019 at King Abdulaziz Medical City, a tertiary care facility in Jeddah, Saudi Arabia.

Low-Grade Endometrial Stromal Sarcoma Extending to The Right Atrium.

Endometrial Stromal Sarcoma (ESS) are very uncommon malignant tumors that make around 0.2% of the entire uterine related malignancies. They represent the endometrial stromal cells in the proliferative stage.

Cyclophosphamide as a Treatment for Focal Segmental Glomerular Sclerosis Recurrence in a Kidney Transplant Patient.

BACKGROUND Primary focal segmental glomerular sclerosis (FSGS) frequently causes recurrence after kidney transplantation, leading to graft loss in half of the patients. Conservative treatment of FSGS is the main acceptable method due to the lack of randomized clinical trials. A few strategies are known to treat FSGS recurrence, such as plasmapheresis and intravenous immunoglobulin (IVIG), but failure to achieve remission may occur.

Implications of COVID-19 pandemic on lung cancer management: A multidisciplinary perspective.

Treatment of patients with lung cancer during the current COVID-19 pandemic is challenging. Lung cancer is a heterogenous disease with a wide variety of therapeutic options. Oncologists have to determine the risks and benefits of modifying the treatment plans of patients especially in situation where the disease biology and treatment are complex.

Expression of Immune Response Markers in Arab Patients With Lung Cancer.

Purpose: Programmed death-ligand 1 (PD-L1) is a marker for checkpoint inhibitor use in the management of solid tumors, especially in non-small-cell lung cancer (NSCLC). Our study was aimed at determining the patterns of PD-L1 expression and cluster of differentiation 8 (CD8) immunostains in patients with NSCLC in the Arab population.

Methods: Archival tumor tissue from patients with a confirmed diagnosis of NSCLC were obtained and stained for PD-L1 with antibody 22C3, using immunohistochemistry staining and giving the tumor proportion score (TPS) as a percentage from 0%-100% of stained tumor cells.

Subsequent Development of Desmoid Tumor after a Resected Gastrointestinal Stromal Tumor.

Desmoid tumors (deep fibromatosis) of the mesentery are rare mesenchymal tumors. They are often misdiagnosed, especially with a previous history of resection for gastrointestinal stromal tumor (GIST). Immunohistochemistry can help differentiate between these two tumors.

An Unusual Variant of Adenocarcinoma of the Left Colon Associated With Microsatellite Instability: A Case Report.

We report a case of colonic adenosquamous carcinoma with MSI-H (microsatellite instability-high) in a 43-year-old male who presented with bowel obstruction due to a circumferential mass involving the descending colon and splenic flexure. Microscopically, it showed poorly differentiated adenocarcinoma with squamous differentiation, tumor infiltrating lymphocytes >3/high-power field, and mild peritumoral lymphocytic response. Immunohistochemistry was equivocal for MLH-1, PMS-2, and MSH-2, with retention of MSH-6 expression.
