OVARIAN-TUMORS WITH FUNCTIONING MANIFESTATIONS

Various categories of ovarian tumors, particularly those of gonadal stromal origin, are capable of producing a variety of hormones that occasionally induce interesting clinical manifestations. The endocrine manifestations associated with gonadal stromal tumors are often due to hormone production by the tumor cells. Sometimes the tumor cells produce only one hormone, while more frequently the hormonal manifestations result from a summation of various hormones including transformation of a variety of prehormones produced by different components of the tumor including its supportive or reactive stroma. The mechanisms involved in the production and transformation of various hormones and prehormones are complex and not thoroughly established at this time. This review will focus on gonadal stromal tumors and discuss evidence available for linkage of the clinical manifestations to hormones produced by the various neoplasms.
