<unk> <unk><unk><unk>  are a diverse group of both benign and malignant neoplasms that develop from the dividing cell population which would normally give rise to cells that surrounds the oocytes, including the cells that produce<unk>  hormones (the nongerm cell and nonepithelial components of the gonads).The yearly adjusted incidence rate is approximately 2 per 1,000,000 women for<unk><unk><unk><unk> (SCSTs). The mortality rate has gradually been declining from1976 (10.0 per 100,000) and 2015 (6.7 per 100,000) by 33%. The age at presentation varies depending on the subtypes of<unk><unk><unk><unk> .<unk><unk><unk><unk> (SCSTs) have more predilection in women of Caucasian background. Rates are highest among Whites, intermediate for Hispanics, and lowest among Blacks, and Asian people.<unk>  may be classified according to WHO into 3 subtypes: Pure<unk><unk> , pure<unk><unk> , mixed<unk>  and<unk><unk> . Histological classification of<unk><unk><unk><unk>  includes granulosa<unk>  cell<unk> , sertoli leydig cell<unk> , gynandroblastoma, and unclassified. The exact pathogenesis of<unk>  is not fully understood. Mutations mainly involving FOXL2, DICER1, STK11 are involved. They are associated with ollier disease and maffucci syndrome.The microscopic pathology varies with the individual subtype of<unk> .Common risk factors in the development of<unk>  include preterm birth, high gonadotrophin levels, increasing age at first pregnancy, obese and non-white women.The symtoms of<unk>  include Adnexal mass, Abdominal & pelvic symptoms, Bloating, Urinary urgency or frequency, Dysphagia(difficulty)eating) or feeling full quickly, Pelvic or abdominal pain. Common complications of<unk>  include malignant pleural effusion,bowel obstruction,ascites. The prognosis varies with the subtypes of<unk>  Most<unk><unk><unk><unk>  present at a low<unk> stage and also prognosis in these patients is excellent. CT and MRI are very helpful in the diagnosis of these<unk> . Surgery and chemotherapy are the mainstay of treatment for these<unk> .
