is the rarest tumor to affect the ovaries
This type of ovarian tumor produces progesterone. The excess of this hormone produces the symptoms that accompany this disease.
Progesterone determines the modifications in the endometrium that block menstruation. The symptoms of this tumor simulate pregnancy.
This type of tumor derives from a previous folliculoma or thecoma that luteinization has endured, acquiring the ability to produce and to accumulate the hormone.
The most common cause of significant hirsutism during pregnancy is due to a luteoma.
