This is a woman with sarcoidosis, as suggested by her hypercalcemia and noncaseating granulomas. The normal demographic for this is an older African-American woman.
In sarcoidosis, there is increased 1,25-(OH)2-vitamin D (active form), leading to increased calcium resorption in the intestine (leading to hypercalcemia). This increased calcium has negative feedback on PTH hormone release, leading to decreased PTH levels as well.
