Laparoscopic cholecystectomy for acalculous, gangrenous cholecystitis on an outpatient COVID-19 adult: a case report.

We report the rare case of an acalculous, gangrenous cholecystitis on a, previously healthy, outpatient COVID-19 adult. The 53-year-old patient presented to the emergency department due to epigastric pain and fever and was admitted to the COVID-19 department. Due to clinical and laboratory deterioration, a computed tomography scan was performed that confirmed the diagnosis of acalculous cholecystitis.

Fine needle aspiration cytology of a primary malignant peripheral nerve sheath tumor arising in the parotid gland: a case report.

Background: Malignant peripheral nerve sheath tumor (MPNST) is an uncommon mesenchymal neoplasm showing nerve sheath differentiation, usually arising in large nerves of the trunk and extremities. Primary location in the parotid gland is rare. We describe fine needle aspiration (FNA) findings in a case of MPNST in the parotid gland.
