A Case of Cytomegalovirus Colitis in an Immunocompetent COVID-19 Patient.

Cytomegalovirus (CMV) is a double-stranded DNA virus that belongs to the herpesvirus family. In the immunocompetent host, CMV infection is usually mild and goes unnoticed. Patients become prone to CMV infection as a result of immunosuppressive drugs or disorders that weaken cellular immunity.

Disseminated angioinvasive basidiobolomycosis with a favourable outcome.

Basidiobolomycosis, a rare fungal infection, is of worldwide distribution but areas commonly involved include the tropical areas of Africa, USA and South East Asia. 88% of the cases are reported among patients younger than 20 years. Many of the case reports in Saudi Arabia are from Tohama area where our patient lives.

A Large Isolated Hydatid Cyst of the Adrenal Gland: A Case Report and Review of the Literature.

A 44-year-old patient presented with two-year history of (R) lumbar pain. There was a strong history of childhood animals' contact, including dogs. A brother had multiple hydatid cysts requiring surgery.

Clinicopathologic features of plasmablastic lymphoma: Single-center series of 8 cases from Saudi Arabia.

Background: Plasmablastic lymphoma (PBL) is a rare subtype of non-Hodgkin's lymphoma. Characterized by its aggressive nature and plasmacytic differentiation, PBL remains a therapeutic and diagnostic challenge; it generally has a poor prognosis with very few long-term survivors and most patients dying within 2 years from initial presentation. PBL has been reported in several other countries; however, there have been no reported cases from Saudi Arabia.

Expression analysis of the mouse S100A7/psoriasin gene in skin inflammation and mammary tumorigenesis.

Background: The human psoriasin (S100A7) gene has been implicated in inflammation and tumor progression. Implementation of a mouse model would facilitate further investigation of its function, however little is known of the murine psoriasin gene. In this study we have cloned the cDNA and characterized the expression of the potential murine ortholog of human S100A7/psoriasin in skin inflammation and mammary tumorigenesis.
