Delayed-onset heparin-induced thrombocytopenia complicated with saddle embolus.

Delayed-onset heparin-induced thrombocytopenia is a rare complication of heparin in which thrombocytopenia and thrombosis occur several days after heparin cessation. We describe a 47-year-old female patient with a history of melanoma and multiple surgeries presented to the emergency department with acute dyspnea and chest pain on the eighth day after discharge.

Erdheim-Chester disease with long-standing diabetes insipidus and generalized edema.

Erdheim-Chester disease (ECD) is a rare non-Langerhans histiocytosis. ECD is detected more frequently due to increased awareness of healthcare providers and improved diagnostic tools. This report describes a 51-year-old woman with a history of weakness, bone pain, xanthelasma palpebrarum, and diabetes insipidus. ECD is a multisystemic condition with a poor prognosis. This disease should be considered in patients with diabetes insipidus, bone pain, and multiorgan involvements.
