Abstract
Sarcoidosis is a chronic granulomatous disease characterized by non-caseating granuloma formation. It usually involves the lung, but may also affects many organs and systems such as the musculoskeletal system, eye, skin, and heart. The data on the course of sarcoidosis during pregnancy are controversial. Generally, sarcoidosis patients do not have a decrease in fertility, and there is no increase in the incidence of congenital abnormalities or premature birth. On the other hand, sarcoidosis may progress during pregnancy. In this report, we discussed the effects of pregnancy on the disease activity in a patient with sarcoidosis.
