A 22-year-old woman was admitted to this hospital because of hypercalcemia and a pelvic mass. One month before admission, abdominal pain developed, followed by abdominal fullness, anorexia, nausea, vomiting, polydipsia, and nocturia. A computed tomographic scan of the pelvis showed a complex right adnexal mass. The serum calcium level was 17.2 mg per deciliter. A diagnostic procedure was performed.

A 57-year-old man was transferred to this hospital because of progressive cognitive decline. Before admission, he had a generalized seizure, after which he was confused, incoherent, and intermittently agitated; he was admitted to another hospital and transferred 5 days later. His wife reported that he had had episodes of confusion for the past 5 years and worsening memory loss and performance problems for the preceding 2 months. He had a history of cutaneous melanoma, alcohol and drug abuse, and occupational exposure to organic solvents. Magnetic resonance imaging of the brain revealed diffuse signal abnormalities in the white matter. A diagnostic procedure was performed.
