A case of paraneoplastic myositis induced rhabdomyolysis due to pancreatic adenocarcinoma.

Rhabdomyolysis is a clinical syndrome characterized by the breakdown of skeletal muscle tissue, leading to the release of myoglobin and creatine kinase (CK) into the bloodstream. The condition clinically presents with myalgia, weakness, and dark urine. It can lead to kidney failure and can be life threatening.

Small-Cell Lung Cancer Presenting as Hypercalcemia.

Hypercalcemia of malignancy is a common and life-threatening complication in cancer patients, typically seen in advanced breast cancer, multiple myeloma, and non-small-cell lung cancer. In contrast, it is rare in small-cell lung carcinoma (SCLC), where parathyroid hormone levels remain mostly within the normal range despite elevated calcium. We present a case of hypercalcemia in a patient with SCLC and discuss its clinical implications.

Active and Mild Chronic Necrotizing Crescentic Glomerulonephritis With Severe Medullary Angiitis in an Elderly Male Patient: A Case Report.

Pauci-immune crescentic glomerulonephritis (GN) is a rapidly progressive form of GN typically associated with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) and may present with rare but severe histologic findings such as medullary angiitis. We describe a 69-year-old male patient with no prior medical history who presented with worsening renal function following a recent hospitalization for what is thought to be pneumonia and presumed prerenal azotemia. On readmission, he was found to have an elevated serum creatinine of 5.

A Rare Case of Scleroderma Renal Crisis.

Scleroderma renal crisis is a rare, life-threatening complication of systemic sclerosis. It is characterized by pronounced hypertension, acute kidney injury, and thrombotic microangiopathy. Although its prevalence has decreased over the last decade, and death rates have declined since the introduction of treatment with Angiotensin converting enzyme (ACE)-inhibitors, it remains a challenge due to lack of prevention and rapid progression despite intervention in those who develop renal crisis.
