Hormonally Functional Ovarian Neoplasms

Hormonally functional ovarian neoplasms are those tumors that secrete one or more hormones that are clinically manifested in the patient. The hormone production may have implications for the diagnosis, management, or treatment of the patient. Hormonally functional ovarian neoplasms include tumors that belong to various histologic categories and produce a variety of hormonal effects. Functional ovarian tumors most commonly produce steroid hormones, and such tumors frequently belong in the sec cordstromal and steroid cell categories. In addition, a wide variety of peptide hormones may be produced by ovarian tumors. Although in most instances the neoplastic cells themselves produce the hormones, a wide variety of tumors may induce their stroma to produce steroid hormones. The stroma of ovarian tumors is derived from the ovarian stroma and may, on occasion, resemble specialized ovarian stroma and its derivatives. Cells resembling luteinized stromal cells or luteinized theca cells may be present and appear to be responsible for the resultant hormone secretion.
