Isolated Renal and Ureter Metastasis as the First Manifestation of Rectal Adenocarcinoma.

Colorectal carcinoma (CRC) rarely metastasizes to the urinary system in isolated form. It usually spreads through direct invasion with intra-ureteric growth or local ureter mucosal metastasis without involving the muscular layer. We present a case of a 63-year-old man who came with uraemic symptoms and a ballotable right kidney.

SARS-CoV-2 Infection in Pregnancy: Placental Histomorphological Patterns, Disease Severity and Perinatal Outcomes.

The association between maternal COVID-19 infection, placental histomorphology and perinatal outcomes is uncertain. The published studies on how placental structure is affected after SARS-CoV-2 virus in COVID-19-infected pregnant women are lacking. We investigated the effects of maternal SARS-CoV-2 infection on placental histomorphology and pregnancy outcomes.

A synchronous incidence of eccrine porocarcinoma of the forearm and facial squamous cell carcinoma: A case report.

Introduction: Cutaneous appendageal tumor can differentiate towards or arise from either pilosebaceous apparatus or the eccrine sweat glands. Appendageal tumors are relatively rare, their clinical appearance is non-specific, and the vast majority are not diagnosed until after excision. Eccrine porocarcinoma (EP), also known as malignant eccrine poroma is a rare adnexal tumor arising from the intraepithelial ductal parts of the sweat gland.
