Hemophagocytic Lymphohistiocytosis Associated With Human Herpesvirus-6 (HHV-6) Infection in an Immunocompetent Adult: A Case Report.

Hemophagocytic lymphohistiocytosis (HLH) is a rare disorder characterized by extreme immune activation and excessive inflammation. It has been reported in patients with familial cases, immunodeficiencies, malignancies, stem cell transplants, and viral etiologies.

A Case of Metastatic Ampulla of Vater Carcinoma Masked Under Recurrent Acute Pancreatitis: A Diagnostic Challenge.

The ampulla of Vater is a small opening located at the point where bile and pancreatic ducts join and empty their secretions into the small intestine. Ampullary cancers are rare but aggressive malignancies that can present with symptoms similar to those of acute pancreatitis, including abdominal pain, nausea, vomiting, and obstructive jaundice. Clinicians must rely on a combination of blood tests, imaging, and biopsies to diagnose ampullary cancer, which may be a hidden cause of acute pancreatitis.

Peripheral T-cell lymphomas are an offshoot of non-Hodgkin's lymphomas and usually carry a poor prognosis. Their clinical manifestations could be very variable and can mimic an infectious or autoimmune etiology. Here, we present a case of a 58-year-old healthy female who presented with fever, cough, and shortness of breath for several days.
