Psoriatic Arthritis
Psoriatic arthritis is a form of arthritis associated with psoriasis. Psoriasis is a chronic skin and nail disease. It causes red, scaly rashes and thick, pitted fingernails. Psoriatic arthritis is similar to rheumatoid arthritis (RA) in symptoms and joint inflammation.
Polycythemia Vera
Polycythemia vera is a rare blood disorder in which there is an increase in all blood cells, particularly red blood cells. The increase in blood cells makes your blood thicker. This can lead to strokes or tissue and organ damage.
Primary Hyperparathyroidism
Primary hyperparathyroidism is a metabolic disorder in which one or more of the parathyroid glands produces too much parathyroid hormone. This can result in a loss of bone tissue. A job of the parathyroid hormone is to keep blood calcium levels from going too low. This is done by releasing calcium from bones. The hormone also conserves calcium that would be excreted by the kidneys, and increases how much calcium is absorbed from food. When the hormone overacts, the result is a rise in the blood calcium level. Too much parathyroid hormone causes too much calcium to be released from bone.
Paget Disease of the Bone
Paget disease of the bone is a chronic bone disorder. It causes bones to become enlarged and deformed. Bone may become dense, but fragile, because of excessive breakdown and deformation of bone. The disease is the most common bone disorder after osteoporosis in people over age 50.

Pheochromocytoma: An Adrenal Gland Tumor
A pheochromocytoma is a rare type of tumor. It grows in the middle of an adrenal gland. A pheochromocytoma causes the adrenal glands to make too much of the hormones epinephrine and norepinephrine. These hormones help keep your heart rate and blood pressure normal.
