Prolactin is frequently increased in sarcoidosis, between 3% and 32% of cases have hyperprolactinemia. this frequently leads to amenorrhea, galactorrhea, or nonpuerperal mastitis in women. It also frequently causes an increase in 1,25-dihydroxy vitamin D, the active metabolite of vitamin D, which is usually hydroxylated within the kidney, but in sarcoidosis patients hydroxylation of vitamin D can occur outside the kidneys, namely inside the immune cells found in the granulomas the condition produces. 1,25-dihydroxy vitamin D is the main cause for hypercalcemia in sarcoidosis and overproduced by sarcoid granulomata.
